Food packaging serves to protect products throughout their journey from production to consumption. However, packaging is often exposed to a variety of hazards during transportation and storage that can compromise its effectiveness and, ultimately, the quality and safety of the food inside. Understanding these hazards is essential for designing packaging solutions that can withstand the physical, environmental, and atmospheric challenges encountered along the supply chain. This chapter examines the types of hazards that affect food packaging during transportation and storage, focusing on the ways in which these factors impact packaging integrity, food quality, and consumer safety. By exploring mechanical hazards, environmental influences, and atmospheric interactions, this chapter provides insights into the crucial role that resilient packaging plays in safeguarding food from production to point-of-sale.

Introduction

Food Safety is the assurance that food is acceptable for human consumption according to its intended use. The slogan of the World Food Safety Day 2019 “If it’s not safe - it’s not food!” portray, unsafe food is a threat to mankind. Ensuring food safety to protect public health and promote economic development is of utmost importance and it remains a significant challenge in both developing and developed countries. Food borne diseases remain a real and formidable problem, causing great human sufferings and significant economic losses. According to WHO 2019-20 World Water Day report, one third of the population of developed countries may be affected by food-borne diseases each year and the problem is likely to be even more wide spread in developing countries, where food and water borne diarrhoeal diseases kill an estimated 2.2 million people each year, mostly children. While unacceptable rates of food borne illness still remain, new hazards continue to enter the food supply.

A food safety hazard refers to any agent with the potential to cause adverse health consequences for consumers. It occurs when food is exposed to hazardous agents which result in contamination of food. In other terms it can be defined as anything that could contaminate food or could otherwise violate established food safety program criteria, if left uncontrolled. The National Advisory Committee on Microbiological Criteria for Foods (NACMCF, 1997) defined a hazard as a “biological, chemical, or physical agent that is reasonably likely to cause illness or injury in the absence of its control”.

A hazard may be introduced into the food supply any time during harvesting, formulation and processing, packaging and labelling, transportation, storage, preparation and serving. Food safety hazards are generally categorized into four classes: Physical, chemical, biological and allergens. Food manufacturers can adopt Food Safety Management Systems (FSMS), which include Good Manufacturing Practices (GMP), Good Hygiene Practices (GHP), Hazard Analysis and Critical Control Point (HACCP) and other practices to strictly check the hazards and make the food safe.

Understanding the hazards that contribute to food borne illness and injury is important to determine the necessary steps to prevent or reduce it to an acceptable level or eliminate hazards altogether before food reaches the consumer.

Abstract

Health-conscious consumers are increasingly seeking functional foods in an effort to control their own health and well-being. The field of functional foods, however, is in its infancy. Claims about health benefits of functional foods must be based on sound scientific criteria. A number of factors complicate the establishment of a strong scientific foundation. These factors include the complexity of the food substance, effects on the food, compensatory metabolic changes that may occur with dietary changes, and, lack of surrogate markers of disease development. Additional research is necessary to substantiate the potential health benefits of those foods for which the diet-health relationships are not sufficiently scientifically validated. Research into functional foods will not advance public health unless the benefits of the foods are effectively communicated to the consumer. Finally, those foods whose health benefits are supported by sufficient scientific substantiation have the potential to be an increasingly important component of a healthy lifestyle and to be beneficial to the public and the food industry. Mounting evidence supports the observation that functional foods containing physiologically-active components, either from plant or animal sources, may enhance health. It should be stressed, however, that functional foods are not a magic bullet or universal panacea for poor health habits. There are no “good” or “bad” foods, but there are good or bad diets. Emphasis must be placed on over-all dietary pattern, which follows the current Dietary Guidelines, and is plant-based, high in fiber, low in animal fat, and contains 5-9 servings of fruits and vegetables per day.

Abstract

The objective of this chapter is to provide an overview of heat pump dryer (HPD) and recent developments in its applications for drying of agricultural and food products. The basics of heat pump dryer, classification, operating principle, configuration and control system have been presented for better understanding. Many researchers have concluded that HPDs use energy more efficiently than electrical dryers. The heat pump dryer is best suited for drying high value commodities such as fruits, vegetables, spices, condiments, herbs, medicinal and aromatic plants at near ambient temperature for producing better quality dehydrated product.

3.1 Introduction

The subject of heat transfer is firmly grounded in the sciences of thermodynamics and fluid mechanics. It has become exceedingly important for engineers to possess a clear understanding of the principles of heat transfer and its application to a large number of problems. In view of process engineering, the knowledge of heat transfer and its application is most important, because heat transfer is one of the basic unit operations in the agricultural processing activities. The design of process equipments, refrigerators, boilers or type of heat exchangers, thermal treatment of food grains, cooling of perishables, pasteurizations, sterilizations, freezing of milk and fruit juices and a large number of similar applications involve consideration of heat transfer rates. There may be other situations where heat is being generated during a certain operation, and may be detrimental to the equipment and the food product. In such cases we are often faced with the task of removing the undesirable amount of heat as far as possible.

1. Herbs and Spices
       
    1.    International Standards Organization (ISO) defines spices and condiments as: Vegetable products or mixtures thereof, free from extraneous matter, used for flavouring, seasoning and imparting aroma in foods.

    2.    Rosengarten describes a spice as a product which enriches or alters the quality of a thing, for example altering the taste of a food to give it zest or pungency; a piquant or lasting flavouring; or a relish. The term ‘spice’ is thus used to cover the use of spices, herbs and certain aromatic vegetables to impart odour and flavour to foods.

    3.    Herbs may be defined as the dried leaves of aromatic plants used to impart flavour and odour to foods with, sometimes, the addition of colour. The leaves are commonly traded separately from the plant stems and leaf stalks.

1. Introduction

Fruit products have their unique identities having large content of micronutrients, polyphenols, vitamins, flavonoids and other nutritional compounds. Characteristic appearance and flavors distinguish among various fruit based products like juice, puree, jam, jelly, squash and other several varieties. Main concern of this fruit processing industry is the stability of the products throughout the post processing storage. Thermal treatment as mean of preservation of these products is the common process implemented so far. It ensures the safety of the product but lacks in retaining the nutritional intact that like of fresh fruit. Today’s consumer demand for minimally processed fruit products and “natural” fruit products tend to think of alternative thermal processing.

High pressure processing (HPP), a relatively new concept compared to conventional thermal processing, also sometimes known as high hydrostatic pressure (HHP), or ultra high pressure (UHP) processing, is a non-thermal food processing method that subjects liquid or solid foods, with or without packaging, to pressures ranging between 50 and 1000 MPa. HPP has already been established itself as an alternative to thermal processing. In food processing it is of great interest due to its ability to inactivate food borne microorganisms and enzymes, at low temperature, without the need for chemical preservatives and it is less detrimental than thermal processes to low molecular weight food compounds such as flavoring agents, pigments, vitamins, etc., as covalent bonds are not affected by pressure. Pressure-treated foods have sensory properties similar to fresh products, which is a major advantage in fruit processing as it matches consumer demand for healthy, nutritious and ‘‘natural’’ products. HPP of fruit products offers the chance of producing food of high quality, greater safety and increased shelf life (Hayashi 1989; Gould 1996; Butz and Tauscher 1998).

4.1 Introduction

The purpose of processing the food is to make it safe and healthy for human consumption. The term food processing refers technologically anything, which transforms raw ingredients into consumer ready products, with the aim of stabilizing food products by preventing or reducing deteriorative changes in quality. The objective of food manufacturers is to develop, modify and employ those processing technologies that retain or create desirable sensory qualities in food and eliminate or reduce undesirable changes due to processing.

The purpose of food processing is to increase the shelf life of food before spoiling (preservation); to remove, destroy or inhibit pathogens and toxins (food safety); to change flavor, texture, aroma, color or form (variety); to reduce preparation times and make food more portable (convenience); to restore and/or raise nutrient levels in food (nutrition).The various food processing methods used extensively in food industry include physical (high temperature, freezing, chilling, dehydration, packaging), chemical (control of storage gases, reduction of water activity, pH, addition of chemical additives or spices) preservation methods.

Traditionally, food preservation has been associated with thermal treatments alone or in combination with biochemical or chemical methods. For example, the thermal processing of milk is done various thermal treatments viz. at 63^oC for 30 min for low temperature long time (LTLT), 72^oC for 15 seconds for high temperature short time (HTST) pasteurisations and up to 140^oC for a few seconds for ultra high temperature (UHT) treatment. However, such thermal treatments effectively reduce level of microorganisms but in long-term preservation, it may lead to losses of desired organoleptic attributes and destruction of temperature liable nutrients and vitamins. The limitations involved with thermal processing has been overcome by employing chemical preservation, cool chain management and process hygiene in the formulation and production of food products.

Food and nutrition are necessary for all living beings to maintain good health[1]. Thermal treatment is commonly used for preservation of food. Although application of thermal treatment can ensure food safety, it may cause undesirable changes in the nutritional, sensory and functional properties of food products[2]. Due to growing awareness of connection between the diet and the health, there is an increase in demands for fresh-like, palatable, additive-free and microbiologically safe food products with high nutritional value and quality[3].

Preserving flowers dates back to earliest recorded history. The first evidence of use of dry flowers was when the bones of a pre historic man discovered in the Middle East were found with a mantle of delicate wild flowers. The pollen grains that remain indicated specific flowers that were used. During ancient times people used to freshen or enliven their rooms with fresh sweet smelling flowers. In the sixteenth century, when the Elizabethan Age was coming to a close, it was considered fashionable to wear silk flowers as part of one’s attire. These days flowers are dried and are versatile in their use. They supply us with food, medicines, ornaments and adornment. Flowers became essential for a fashionable appearance. Each civilization developed its own interpretation of flowers. Pressed flower art became popular in Victorian times. The Japanese use pressed plants and colorful papers to create Oshibana Art.

Microorganisms (or microbes) are organisms too small to be seen with the naked eye. The science of microbiology is the study of microorganisms, their properties, classification, growth requirements, method of reproduction and distribution in nature. These organisms range in size from tiny viruses to larger bacteria, protozoa, algae, fungi and some of the microscopic worms (helminthes). They are present everywhere in our environment, in our homes, on our bodies, on the things we touch and on the food we eat. They are important for human survival on Earth, playing an essential role in many processes that maintain life. In nature, microorganisms carry out a number of important functions.

1.They are responsible for the decomposition of organic matter.

2.Recycling of nutrients that help to maintain the balance of chemicals in the soil.

3.Special nitrogen-fixing bacteria live symbiotically with certain plants, absorbing nitrogen from the air and converting it into compounds which can be used by the plant for growth.

4.Some algae are capable of photosynthesis, using energy from the sun to convert carbon dioxide in air into carbohydrate.

5.Marine microorganisms form the basis of the food chain in lakes, rivers and oceans.

6.Certain microorganisms are used in the manufacture of food.

7.Pharmaceuticals and drugs.

8.Industrial processes.

9.A valuable tool for scientific research.

10.Use in laboratory experiments to understanding metabolic pathways and in the discovery of the genetic code.

13.1 Introduction

Hospitality industry is the second largest industry in the world. It is well diversified and can be chosen as per the interest. Hospitality management involves planning, organizing, directing and controlling human and other resources within the different segments of hospitality industry i.e. lodging, restaurant, travel and tourism, institutional management, recreational management, meeting and convention planning industries. Although, these all are separate but related segments of the hospitality industry and are interrelated to provide good and efficient services to the guests and users. Hospitality industry provides services which are need oriented and differ in various parts of the world as per regions and the traditional styles.

The first building created specifically for hotel was ‘City Hotel’ with 73 rooms at 115 Broadway, New York in 1794. Pallonjee Pestonjee established the very first western-style hotel in India, “The Bristol Hotel” in Mumbai in 1840. According to the report of the department of Tourism, Government of India, at the end of the year 2004, there were 167 Five star hotels with approx. 28,900 rooms, whereas 126 Four star hotels, with 8,831 rooms [2]. To expedite the ongoing process of classification/re-classification of functioning hotels in one to three star categories, five Regional Committees have also been set up in Delhi, Mumbai, Kolkata, Guwahati and Chennai to conduct inspection [3].

According to Futter (2001) it is very important the way we cook our food. If the cooking is inadequate it causes food poisoning. While cooking there can be cross contamination starting from raw foods. It includes hands or utensils which can cause food poisoning. Most foods, especially meat, poultry, fish and eggs should be cooked thoroughly to kill most types of food poisoning bacteria. Generally the food should be cooked to a temperature of 75 °C or hotter. When food is cooked, it should be eaten promptly, kept hotter than 60 °C or cooled, covered and stored in the fridge or freezer. Some people are more at risk from food poisoning than others. In order to buy safe food in the market like buying pre-cut produce as a half a watermelon or cut veggies from a salad bar, it is important to choose items that are refrigerated or surrounded by ice. They must be kept in separate bags. FDA (2019) has studied the contamination in lettuce. Shopping at a farmer’s market is a great way to get locally-grown, fresh fruit, vegetables, and other foods. However, safety of these produce needs to be checked. Many markets have their own food safety rules and vendors must comply with them along with the government regulations. Fruits and vegetables must be washed thoroughly under running water just before eating, cutting or cooking. Fruits and vegetables must never be washed with soap or detergent or using commercial produce washes. Even if it has to be peeled before eating, it is still important to wash it first. Any bacteria present on the outside of items like melons can be transferred to the inside when it is cut or peeled. They should be refrigerated within two hours after preparation. The juice or cider must be treated (pasteurized) to kill harmful bacteria. Pregnant women, children, older adults and people with weak immune systems should drink only pasteurized or treated juice. Raw milk can harbor dangerous microorganisms like Salmonella, E. coli, and Listeria. World India (2017) has looked into the food regulations. These can pose serious health risks. Pregnant women, older adults and people with weakened immune systems are at higher risk for illness caused by Listeria. One source for these bacteria is soft cheese made from unpasteurized milk. It is vital to check the label to make sure that it is made from pasteurized or treated milk. Make sure that eggs are properly chilled at the market. FDA requires that untreated shell eggs must be stored and displayed at 45°F. While buying eggs it needs to be ensured that the eggs are clean and the shells are not cracked. Meat should be properly chilled even in the market and kept in closed coolers with adequate amounts of ice to maintain cool temperatures. If it is brought in an insulated bag or cooler during transit it is very beneficial to keep the quality. It should be always kept separately from your other purchases, so that the juices from raw meat (which may contain harmful bacteria) do not come in contact with produce and other foods. Essays (2018) have written a very comprehensive overview of food safety.

Today, organic and local foods are preferred as they use less pesticides or fertilizers. However, these foods, like others, can be exposed to harmful bacteria during the growing and harvesting process. The farmers and distributors must use good sanitary practices to minimize food contamination. Consumers should cook food properly. The street food vendors are a traditional and indigenous fast food approaching in most countries of the South-East Asia Region. As these are economical they cater to millions of consumers. Among safe street foods there are many contributing factors that are associated with the safety of street food. WHO had conducted a survey in 1993 covering 100 street foods in 100 countries around the world. It revealed that the major health threat comes from raw and undercooked food, infected food handlers and inadequate hygiene practices in processing and storing such food. If the street food is cooked well and is served hot, then the chances of food poisoning is less. The water quality, hygienic conditions and the level of cleanliness especially in the summer season are the major factors for food poisoning. However improvements in physical infrastructure and hygienic conditions are growing as consumers are also demanding quality food. Michael et al., (2017) have looked into organic versus conventional foods.

INTRODUCTION

The concept of hurdle technology has been developed as a new way to realize safe, stable, nutritious and economical foods. It employs combination of different preservation techniques to achieve a multi-target, mild but reliable preservation of foods. The application of hurdle technology in food preservation is increasing rapidly worldwide. Over the years, insight into the hurdle effect has been broadened and the application of hurdle technology has been extended. A better understanding of the occurrence and interaction of food preservative factors (hurdles) in foods is the basis for improvements in food preservation. If the hurdles for the microbes are known, the microbiological stability and safety of this food might be optimized by changing the intensity or quality of these hurdles. Using the proper combination of hurdles, it is possible to improve not only the microbial stability and safety but also the sensory and nutritive quality as well as the economical aspects of food. The hurdle concept is also referred to as food preservation by combined methods, combined process, combination preservation or combination processing techniques. The hurdle effect is of fundamental importance for the preservation of foods. The illustration of hurdle effect was first introduced by Leistner in 1978. Based on the understanding of hurdle effects, the concept of hurdle technology was derived (Leistner 1985).

Safe, wholesome and nutritious food is vital for sustenance, good health, food and nutritional security and augmentation of sustainable development of an individual. Also, safe food helps in the growth of the national economy and enhances the trade and tourism sector. Foods that are unsafe containing various kinds of microorganisms can cause chronic diseases or illnesses varying from diarrhea to cancer.

To ensure safe food and adequate sanitation programs, the equipment used for processing of food products must be designed, fabricated, constructed, and installed according to sound hygienic design principles. This ensures the equipment can be adequately cleaned and sanitized, and that surfaces are resistant to daily exposure to corrosive food products and cleaning/sanitizing chemicals. This chapter focuses primarily on fundamental principles of hygienic design, which protect the product from microbial, chemical, and foreign-body contamination. This is followed by a discussion of general aspects of hygienic construction and design of food equipments, the selection of materials of construction and specification of surface finishes, fabrication, installation and cleaning and sanitization. Quality of raw materials or foods ingredients, proper processing, packaging and storage of finished products decides the quality of the food products. Planning for plant and equipment layout, its design, services (water, air, refrigeration, steam), waste disposal etc. are some of the critical factors, which contributes to quality. In addition, the food processing equipment must comply with strict standards and regulations, which are necessary for securing the quality and safety of the food products to the consumers.

Ice bank cooling: Storing of fruit and vegetable in storage chamber with positive ventilation and system countries where ice formation is allowed during night time (as electricity cost of night is less as compared to the day time). Melting of ice occurs during day time and with proper air circulation by means of ventilation process, approximately 0.5 10C temperature with 90% RH in the chamber is maintained. Ice Bank Cooler / Air forced cooler leads to desiccation of the produce (Plate 359). So use forced air high humidity cooler and these are known as Ice Bank Cooler. Ice bank coolers are useful for strawberry.

Ice cream: Ice cream may be define as frozen dairy product made by suitable blending and processing of cream and other milk products together with sugar and flavour.

Ice cream cone: A thin crisp edible cone for holding ice cream and filled with ice cream.

Ice point: It is the temperature of equilibrium between ice and water under normal atmospheric pressure (Plate 360).

Ichthylogy: It is the branch of the zoology that deals with the study of fishes (Pisces).

Icicle: It is small tapering piece of the ice formed by freezing of dropping water (Plate 361).

Identification of paper and paperboard.

Introduction

Paper can be broadly classified into two categories: coarse papers, which are normally made of unbleached Kraft softwood pulp and used for packing, and f ine papers, which are usually composed of bleached pulp and used for writing paper, bond, ledger, book, and cover sheets.

The main types of packaging papers are:

Kraft paper

Usually produced on a Fourdrinier machine, kraft paper is gritty and incredibly strong. It is then either machine-glazed on a Yankee dryer or machine-finished on a calendar. Sometimes it isn't calendared so that the rough surface will keep the bags from slipping over one another when they're stacked on pallets.

Introduction

Seasonal or annual fluctuation in weather patterns is termed as climate variability. However, climate change is a change in the mean state of weather statistic over three decades of time period. Climate change is exacerbating the challenges faced by the agriculture as well as horticulture sector. For last 10 years, Asia is facing the serious threats from climate change and variability such as tsunami, f loods and droughts. Extreme events are expected to have large negative impacts on crop productivity. The rise in temperature and reduction in rainfall under semi-arid environments are likely to reduce production of fruits, vegetables and flowers in the coming 20 years. The production and quality of fresh fruit and vegetable crops can be directly and indirectly affected by exposure to high temperatures and elevated levels of carbon dioxide and ozone. The rise in atmospheric CO2 levels due to global climate change and horticultural practices has both direct and indirect effects on secondary metabolite synthesis in plants.

2.1 Introduction

Each step in the food industry system e.g. food production, processing, transportation, storage, distribution and marketing, has some impact on the environment and there is much concern about environmental pollution. Due to the highly diversified nature of the food industry, various food processing, handling and packaging operations create wastes of different quality and quantity, which, if not treated, could lead to increasing disposal problems and severe pollution problems [24]. The preservation of the natural environment from industrial pollution is currently receiving much attention. In food industry, the most important problem is treatment and disposal of large quantities of waste water, a by-product of various processing operations. It is one of the largest industry groups comprising the manufacturing sector of the U.S. economy [47]. Likewise, India is the world’s second largest producer of food next to China, and has the potential of being the largest food processor. The total food production in India is likely to double in the next ten years [22]. Flour and grain; soft drinks and carbonated water; breweries; starch and miscellaneous food products; meat, poultry and fish; tea, coffee and other beverages; fruit juices; animal feed; sugar; distilleries and blending of spirits; cocoa, chocolates and sugar confectioneries; agricultural and food chemicals and industrial packaging are important sub-sectors of the food processing industry. Food processing projects involve the processing and packaging of meat products, fish and shell fish, dairy products, fruit and vegetables, grains and beverages production. It includes refinement, preservation, improvement of product, storage, handling, packaging and canning (Fig. 1). The processing may involve receiving and storing raw or partially processed plant, animal or other food materials, processing the raw materials into finished products, packaging and storing the finished products.

Food provides a sense of wellbeing and comfort and makes people feel good. In this world of a growing population, the need for affordable, safe and good quality food is rising constantly. On the other hand, there is growing awareness of customers who demand that food be produced and supplied hygienically in socially responsible and eco-friendly ways.

Acinetobacter baumannii is an opportunistic pathogen giving rise to nosocomial infections causing threat to public health. Studies of biofilm-forming genes was done in A. baumannii isolates by PCR technique. To study the relationships of genes a technique based on PCR sequences along with multilocus sequence typing (MLST) were utilized (Saeed et al., 2020). Goudarzi, Mehdi et al. (2019) studied the genetic diversity and biofilm formation analysis of Staphylococcus aureus causing urinary tract infections in Tehran, Iran. The biofilm forming and adhesion encoding genes were studied along with distribution of different agr and spa types in S. aureus isolates by PCR screening and multiplex PCR. The workers found that the ability to produce biofilm was higher among MRSA strains as compared to MSSA strains. The most prevalent biofilm forming gene was icaD (77.3%), followed by icaA (76%), icaB (57.3%) and icaC (50.7%). Acinetobacter baumannii is a nosocomial pathogen which is commonly present in hospitals and is a causal organism of many diseases. A. baumannii isolates have been known as multidrug-resistant (MDR). For controlling such serious organism only molecular techniques have been found to be effective. 

Abstract
 
Drying is one of the most popular methods used for preserving products and extending their shelf lives by reducing moisture content to a low level to prevent microbial spoilage and moisture-mediated deteriorative reactions. As an efficient technology with high heat and mass transfer rates, impingement drying has been commonly used in various industrial drying such as tissue paper, textiles, photographic films, coated paper, nonwovens, carpets, lumber etc. In the past two decades, air impingement technology has got more and more attention in the field of food and agricultural products processing.

Introduction Rice cultivation is a means of livelihood for a large number of people from the state of Assam, India (Saikia, 2019). It is related to the cultural aspects in rural Assam where people indulge themselves in traditional as well as modern ways of farming. Like any other north-eastern states in India, rice majorly dominates the Assamese cuisine. It is the primary source of diet in Assam. There are more than 100 varieties that are genetically modified breeds in which indigenous varieties contribute to 20 germplasm (https://www.rkbassam.in/). The different rice varieties of Assam have different culinary applications in both savoury and sweet cuisines. The intermediate and high amylose rice, parboiled or nonparboiled are consumed as staple for major meals while the low amylose rice is mostly consumed as snacks, breakfast cereals and desserts. The major constituent of rice is starch consisting of about 90% of the mass. Thus, the major compositional changes occurring in rice is due to starch. Starch is a polymer of glucose linked by glycosidic bond. It consists of amylose (linked by alpha 1- 4 linear chains) and amylopectin (alpha 1-4 & alpha 1-6 branched chains). On the basis of composition, rice is classified as high amylose (>25%), intermediate amylose (20 -25%), low amylose (7-20%) and waxy or glutinous (1–2%) types (Juliano, 1979).

The food we eat contains nourishing substances called nutrients which are required by human body for proper functioning and maintenance of body health. They are classified into five groups such as:

Carbohydrates,

Protein,

Fats,

Minerals

Vitamins

India, one of the largest food producer countries (I in milk production, II in fruit and vegetable production and III in food grain production at world level), possesses the potential of being the biggest with the food and agricultural sector contributing around 26 percent of the Gross Domestic Product (GDP). It is a paradox that people of the country producing such huge quantities of food including fruits, vegetables, milk, cereals grains etc. are still suffering from many nutritional deficiencies in their diet, and even in some places, the stomachs of people remain unfilled for the want of food. The credit of this would predominantly go to the poor postharvest infrastructure as well as knowhow and accessibility to the facilities. All this makes us one among those countries having largest postharvest losses. The reduction of losses occuring during food handling, processing, storage, distribution and use would be an indirect way of increasing the food production and making the country self-sufficient in nutritional requirements.

Indian Spices: These are dried, fragrant, aromatic or pungent vegetables or plant substances. They can be whole, broken or in ground forms. Primary function in food is seasoning rather than nutrition and which contributes to the flavour and piquancy in foods and beverages. These have been used as food additives widely since ancient times [http://www.imedpub.com/articles/herbal-medicines-possible-risks-andbenefits.pdf,https://www.ncbinlm.nih.gov/pmc/articles/PMC3170500/pdf/nihms307509.pdf). They also exert digestive stimulant action of food enhancing the taste. A few medicinal properties of spices are as being a tonic, carminative, stomachic, diuretic and antispasmodic (Aboaba et al., 2011; Achi, 2006 and Adefegha et al., 2012). This has led for pharmacological applications in the indigenous systems of medicine as digestive stimulants and to relieve digestive disorders and makes the food more palatable. In many countries around the world these are grown and reared for the purpose of trade and distribution. In the ancient times the spice merchants have been the most popular traders. India is well known for spices with a wide variety of recipes that are laced with them.

1. INTRODUCTION

Admitably except for water and milk, no other beverage has earned such universal acceptance and esteem throughout the ages as wine. The aesthetic postures of wine can be gauged by the quotations like ‘wine is the most healthful and the most hygienic beverage (Louis Pasteur)’, ‘wine is a chemical symphony (Amerine). Man has been preparing and consuming since time immemorial a large variety of alcoholic beverages, ranging from mild stimulants to highly intoxicants liquors. Amongst the mild stimulants are the wines which have long association with human artistic, cultural and religious activities.

Grapes and wines are of immense importance to us and their sheer magnitude of production and associated investment, employment, enjoyment, tax revenue collected and the economic contribution is a justifiable. These play a major role in economics of major wine producing countries like Italy and France. Wine and brandy refer to the fermented by-products of grapes, member of genus Vitis notably the cultivars of V.vinifera L. as per the European definition. However, here these terms may also refer to the fermented by-products from any fleshy fruit or flower. Compared to the grapes, industry producing wine from other fruits is very small. Do these have any role to play especially in nutrition, health and economy of the horticulturally developed countries or are simply mild intoxicants consumed? Such queries at one or the other time may baffle the thinking of an inquisive reader. An attempt has been made here to discuss briefly the historical aspects, role of wine in the context of nutritive and therapeutic value, present status of Indian Wine Industry, research status and future strategies. Emphasis on its role in developing the horticultural industry would also be laid.

India is a second largest producer of fruits and vegetables after China. These share are 10% and 16% respectively in total world production. Horticulture crops occupy 23.548 million ha and production is estimated around 260.063 million tones. Total area of fruits, vegetable, plantation crops, spices, loose flower and aromatic plant are 7012, 9083, 3606, 3092, 218 and 537 thousand ha, respectively and production are 79400, 156445, 16388, 5786, 1421 and 622 thousand tones, respectively with productivity are11.32, 17.22, 4.54, 1.87, 6.59, 1.19 thousand tones per ha, respectively (2012-2013). The total productions of cut flowers are 74305 Lakh stem (2012-2013). The annual horticulture export volume is 2733145 metric tonnes (2010-2011) with total exported value of Rs 696461 lakh. In terms of volume, fresh fruits & vegetables comprised about 76 % of exported horticulture produce followed by processed fruits & vegetables (23 %) and floriculture & seeds (1%). After that losses found 20-30 % in fruit and 30-40 % in vegetable while harvesting to consumption in India. It’s due to the perishable nature of horticulture commodity, non availability of appropriate post harvest infrastructure transportation, inadequacy of the market or lack of processing.

India is a major horticulture producer, even though processing is less than 2 %. This is very low as compare to 80 % of Malaysia, 78 % of Philippine, 70 % of Brazil and 30 % of Thailand. The most of developed country 40-60 % fruits and vegetables utilize in processing.

Proper handling, packaging, transportation and storage reduce the post harvest losses of fruits and vegetables. For every one percent reduction in loss will save 5 million tons of fruit and vegetable per year. Processing and preservation technology helps to save excess fruit and vegetable during the glut season. The technology has become a necessity to improve the food safety and strengthen nations food security. The technology helps to boost export of agricultural commodities in the form of preserved and value added products.

    1.    Control points are the points in the food processing chain where it is possible to control or remove hazards.

    2.    Critical control points are the control points in the processing chain where it is essential to a hazard, usually because there is no later step at which to establish control.

    3.    Preventative measures are the actions and activities needed to remove hazards or control them by reducing them to acceptable levels.

    4.    Critical limits for critical control points are measurements such as temperature and time, that must be met, or characteristics such as appearance and texture. Critical limits need to be validated.

    5.    Monitoring is the regular measurement or observation of a critical control point to ensure it is not beyond its critical limits.

    6.    Take corrective action to bring the process back under control before the problem (‘deviation’) leads to a safety hazard. Consider proper management (disposition) of any adversely affected product.

    7.    Verification procedures are tests and programmes that make sure the HACCP system working properly

    8.    Record keeping and documentation systems must meet the needs of the business and be adequate to show that the food safety programme is working.

Abstract

Sunflower seeds of variety PSFH- 67 were obtained from the PAU seed farm. These seeds were cleaned with commonly used seed processing equipment. Samples were divided into 2 parts. One part was kept as such for taking the observations of feed (control) and the remaining part was passed through specific gravity separator for its refinement. The various fractions obtained were recovery (heavier, healthy seeds), middlings (intermediate, under size) and rejections (lightweight seeds, wevil eaten, foreign matter). The respective percentages of each fraction were computed. These graded fractions as well as the feed were packed in 2-kg cloth bags and stored under ambient conditions. Different quality parameters viz. moisture content, physical purity, percent germination, thousand grain weight and vigour index were recorded at 30 days interval from Jan, 2010 to Apr. 2010. The physical purity, moisture content, thousand grain weight, percent germination, root length, shoot length and vigour index were found to be higher in recovery and minimum for rejections while moisture content was highest for rejection compared to all other fractions. The physical purity remained more or less constant throughout the period of storage. The thousand-grain weight showed a rapid decrease during first month thereafter it remained constant. There was continuous decrease in percent germination with the period of storage irrespective of the treatment.

India is emerging as a major stakeholder in the global horticulture scenario accounting for 10.00 % of the world production of fruits. This has been made possible due to concerted efforts of scientists and progressive farming community. In recent years, there is considerable awareness about the nutritional security and food safety. Underutilized fruit trees not only provide nutrition and income security to the people but can also ameliorate the harsh environment of the semi-arid and arid region. Jamun has been named as diabetes fighter for its hypoglycemic (lowering blood sugar) properties.The minor fruits like bael, karonda, khirni, mahua, tamarind, mulberry, pilu, chironji, phalsa and wood apple have tremendous scope for their proper utilization. These fruits are nutritionally rich in bioactive compounds and some of these are of great medicinal value, processing quality and other uses. They have a growing demand in local as well as export market and for processing besides diversification in agriculture in the wake of global changes in weather conditions.

Introduction

The semiarid and arid ecosystem is not only neglected in India but also the whole world in respect of socio-economic and scientific development. Middlefon and Thomas, 1997) reported the arid and semi arid covers 47% of land surface of the plant and home town to 1/3 of human population. Conventional plant breeding so far only increased the yield of crops grown under arid tropics at about half the rate achieved for crops grown in temperate regions (Turner, 2004, b). The major crop of other ecosystem are considered as under exploited crop of arid ecosystem. Tomato (Lycopersicon esculentum Mill.), is one such crop, which was domesticated in ancient Peru, has become the most popular and widely consumed vegetable in the world today, for its rich flavor and high nutritional value (Vitamins A and C)

Abstract

India has got a pool of medicinal herbs which are proved to be beneficial in curing various diseases. Their regular consumption not only will improve the health status but also reduce risk of lifestyle diseases. Though simple solutions, associated colloids, suspensions and emulsions are some of the traditional techniques for encapsulating functional agents, micro-encapsulation techniques is the most successfully employed technique for the controlled release of sensitive bioactive compounds. Owing to the targeted delivery of functional components directly to the human gut system, emulsion based delivery system are getting more attention now-a-days. With advancement in science, more complex and novel structures can be created which can successfully deliver these nutraceutical and bioactive ingredients into existing food systems. The technological interventions in emulsion science have opened great opportunities to improve the delivery of bioactive herbal components into milk and milk products. Various milk and milk products functionality can be improved in this way which will improve the gut- microflora within short period of time after consumption.

Introduction

Plants contain a variety of substances of nutraceuticals importance which are useful medicines, food additives, cosmetics and health supplements etc. However, low availability under in vivo condition, decreased plant resources, increases in labour cost and other problems in obtaining these high-value added substances from natural plants have pointed toward the use of in vitro techniques for production of the products. Because in vitro cultures are not affected as the production affected under in vivo conditios.This has led scientists and biotechnologists to consider plant cell, tissue and organ cultures as an alternative way to produce the corresponding secondary metabolites.Therefore, studies on the production of useful metabolite by in vitro techniques have been carried out on an increasing scale since the end of the 1950’s. The large scale cultivation of tobacco and various vegetable cells was examined in the late 1950’s and early 1960’s in the U.S., Canada, and Europe. At present, several firms are manufacturing a plant pigment, shikonin, and ginseng cell biomass on a commercial scale and several other products including anti-oxidant products.

Research efforts on in vitro derived extracts is well documented on each of these major product categories: flavors (onion and garlic, peppermint and spearmint, fruit flavors, chocolate aroma, seaweed flavors, vanilla, celery, coffee, spice, sweeteners, and so on); edible colors for foods and medicines (mainly betalains and anthocyanins): non-food pigments for cosmetics and textiles (shikonin, berberine, and various other products); several examples of fragrances and essential oils; and bioactive natural insecticides and phytoalexins useful in current integrated pest management programs. Of course, intensive activity has centered on production of natural drugs of chemoprotective compounds from plant cell culture. Some of the most prominent pharmaceutical products in this latter category include ajmalicine (a drug for circulatory problems) from Catharanthus roseus and taxol (a phytochemical effective in treatment of ovarian cancer) from Taxus species.

Incentives are a powerful stimulus to transfer of technology. They can encourage researchers to get their results to market, a new career path for many of them. They can create a culture that attracts and retains entrepreneurial staff, scientists, students and technology transfer professionals (TTPs) that view the university as a career path and a vehicle for making a contribution to society. Working in a pro-entrepreneurship team of colleagues can also lead to getting people to think in terms of making a connection between their work and its application. Incentives can be short-term or long-term in nature, and can be tailored to individual or collective requirements. As it is likely to be challenging for universities to design incentives that cater to every researcher’s or TTP’s desire, they can design incentive programs to cater to various aspects of human. Nature.
12.1 Why incentives matter in this ecosystem
Incentives can be either financial and non-financial. These are needed to ensure that researchers and TTPs remain motivated, aligned with institutional goals, and committed to the long-term process of technology transfer and commercialization. Incentive programs serve several important purposes:
• Motivation: Incentives energize individuals to pursue innovation and commercialization, often over long- and uncertain-time horizons.
• Retention: By offering recognition, rewards, and career advancement opportunities, institutions can retain high-performing researchers and skilled TTPs.
• Alignment: Well-designed incentives ensure that the personal goals of stakeholders align with institutional and societal objectives.

Introduction

Soil is one of the elements required for farming and it provides nutrients to the plant. Healthy soil containing all the elements for growth and development of crop as well as heart of soil health is the integration of the soil physical, chemical, and biological process and its functions. But inorganic farming adopted over the recent years to maximize crop production has become Hazardous because in the long run deteriorating the soil health and the quality of the agricultural produces besides polluting the environment and natural resources of soil and water dangerously. Soil testing helps to recommend chemicals fertilizers more judiciously in combination with organic manures and bio fertilizers and hence balanced nutrition to crop. Soil health and fertility is the basis for sustainable profitability of the farmers. Soil testing is a science based and time-tested tool for assessment of soil fertility status and soil ailments and for nutrient amendment recommendations.

India has a population of one hundred twenty four crore plus and feeding this large a population calls for a strong FPI. The industry also assumes importance in the national economy due to the immense employment generation opportunities it offers and the export revenue it earns. Food Processing Industry (FPI) in India is a sunrise sector that has gained prominence in the recent years. Easy availability of raw materials, changing lifestyles and favourable fiscal policies has given a considerable push to the industry’s growth. FPI serves as a vital link between the agriculture and manufacturing sectors of the economy. Strengthening this link is critical to reduce wastage of agricultural raw materials, improve the value of agricultural produce by increasing shelf-life as well as by fortifying the nutritive value of the food products and ensure remunerative prices to farmers as well as affordable prices to consumers. The industry has very low processing level i.e., 2.2% for fruits and vegetables, around 35% in milk, 21% in meat and 6% in poultry products, which is significantly lower by international standards. For e.g., processing of agriculture produce is around 40% in China, 30% in Thailand, 70% in Brazil, 78% in the Philippines and 80% in Malaysia. Value addition to agriculture produce in India is just 20% with wastage estimated to be valued at around US $13 billion.

India has the second largest producer of food with arable land of 159.65 million hectares and has the highest acreage under irrigation. Next to China, India ranks second largest food producer in the world and has the potential to immerge the biggest with its food and agricultural sector. India accounts for less than 1.5% of international food trade despite being one of the world’s major food producers, which indicates huge potential for both investors and exporters. Food and food products are the biggest consumption category in India

Abstract

There is an urgent need to – create market driven linkages rather than do it alone by building new infrastructure. A lot needs to be done to improve infrastructure in terms of reducing the logistics cost, eliminating middlemen influence and eliminating the wastage of basic inputs. There is a need to blend technologies based on principle of dovetailing production for masses with the advantage of mass production, particularly in the area of grain processing, packaging and marketing which would help combine livelihood, security with agricultural competitiveness. Risk in crop production is not new to any age and the farmers have been bearing it since times immemorial. The farmers should be allowed to maximize their grain. High performance continuous and batch dryers remove moisture in a way that is predictable and reliable. The problems associated with moisture content may be harmful to international trade in grain and need to be addressed adequately by the standardization institutions.

About 60-70% of total food grain production is retained and stored by farmers for household consumption, use as seed, feed for cattle and payment of wages to labours etc. in our country. Yet the quality of grains stored is not so good, and hence, preserving the harvested crops without loss or damage has always been a problem of national importance. This study was conducted in Jabalpur district of Madhya Pradesh state. A tribal block namely Kundam was selected for study purpose. The responses of 120 women were recorded in pre-tested structural schedule through interview. Rural women are an important source of information on the use of indigenous practices for grain storage. The data reveals that the majority of respondents are using dry leaves of Neem, dry onion bulb, wheat straw, Nirgudi leaves, roots of bach etc. for storage of grain at household level. In our country, indigenous practices of grain storage have always been and are still followed, because it is supposed that these practices are useful in control of grain loss.

Jamun (Syzygium cuminii L. Skeels) is an evergreen tropical tree which belongs to family ‘Myrtaceae’. It is commonly known as java plum, jambul, jamun, black plum, faux pistachier, Indian blackberry, doowet and jambolan. Jamun is native to the subtropical Himalayas, India, Sri Lanka, Malaysia and Australia. Its fruits are delicious and have great importance in folk medicine (Ayyanar and Subash, 2012).

Introduction

Rice, being an important crop in India, there is a part to focus on improving rice production and productivity. A number of biotic and abiotic factors mostly referred as production constraints that affect the rice yield adversely and subsequently, needs an extraordinary consideration to the developing demand of continuously emerging population of India (Kumar and Jha, 2000). Abiotic stress has been estimated that more than half of the yield potential of major crops is mainly affected due to unfavourable growing environments such as drought (Cortina and Culianez-Macia, 2005). The current study was aimed to carry out to assess the impact of Pink pigmented facultative methylotrophs (PPFM) and plant growth promoters on mitigating drought stress effects in semi dry rice.

6.1. Introduction
The best way to combat malnutrition globally among women and children have changed over the last few years keeping pace with the advancement of technology. Information and communication technologies (ICT) have become very important for solving the contemporary nutrition related issues because they provide a vast array of new communication capabilities. In addition to meeting society’s actual needs for ongoing health and nutrition care, ICTs are crucial for facilitating interactive, personalized nutrition communication. People can interact or communicate with others in different countries in real-time through instant messaging, video conferencing or voice over IP (internet protocol). Through social networking platforms like Facebook, Instagram, and others, people from all over the world can regularly converse and stay in touch. In the context of health communication, ICT is referred to as Interactive Health Communication (IHC), which is the exchange of health information and advice and support regarding health-related matters between a consumer, patient, caregiver, or professional using an electronic device or communication technology. Nutrition treatments are less expensive when face-to-face interaction is facilitated by electronic means. These are complementary factors that encourage nutrition communication in an information-age healthcare system, especially when combined with consumers’ growing desire to take charge of their own health. Customers can advantageously use information technology in this system to connect with health professionals and support groups, obtain absolutely relevant information, and take charge of their own health. The “global village,” which has been made possible by modern information and communication technology, allows people to interact with each other virtually as if they were neighbours. Because of this, ICT is frequently examined in relation to the ways that contemporary communication technologies influence society.

INTRODUCTION

Now-a-days, food products with maximum health benefits and ease in preparation are gaining popularity globally, the reason being changing awareness level about food and dietary habits. Since ages, a number of methods like cooking, baking, drying etc. have been used to thermally process the food materials. Electrical sources of electromagnetic waves are very promising because of advances in nuclear and hydroelectric power as well as ongoing cost rises in traditional forms of fuel, of which there are only restricted reserves. The heating aids include use of wooden fuel, gaseous fuel, electric energy etc.; but the new era of electromagnetic rays had introduced new horizons of food processing by utilizing it in various unit operations (Sakai and Hanzawa 1994). Though, these radiations are gaining popularity in various walks of life; their destructive impact is much dominating. Hence, one should handle these radiations with utmost care as well as comprehensive understanding of the know-how and control over the process.
