Abstract

The constant improvement in automation of bakery industry has placed higher demands on wheat. As a consequence bakery industry requires wheat possessing specific quality attributes. In view of this, there is need to produce good quality wheat not only for good chapattis but also for better bakery products viz., bread, biscuit, noodles, pasta products. New technologies are emerging which could be exploited for determining the Indian wheats for their suitability for various value added products. In the current investigation, 50 genotypes possessing low protein content (<10.5%) selected from a vast amount of breeding material were analysed for their biscuit making attributes. These lines were screened by actual baking test and alkaline water retention capacity (AWRC) test keeping the standard prescribed for biscuit making qualities viz., low protein content, low sedimentation value, low AWRC and larger diameter with larger spread factor of biscuit. Further with the help of Stable Micro Systems TA.HDi Texture Analyser the biscuits were analysed for hardness and crispness. Correlation coefficient among 8 quality traits suggested highly significant and positive correlation between sedimentation value and AWRC, biscuit diameter and spread factor, and biscuit hardness and fracturability, and significant negative correlation between biscuit diameter and its thickness. On the basis of findings, genotypes identified for biscuit making qualities may be used as donor for developing varieties suitable for biscuit making.

Introduction

Food ingredients sector is indicating ample prospects for growth. The segment is an obligatory element for the growth of the food and beverage sector. These ingredients are also driving the development of the healthy functional foods industry to increase by 20% growth annually. Innovation in the food and beverage market, especially in the processed food domain, has created innumerable opportunities for new product development in the ingredients market as well. The segment is driven by the growing food processing industry and India is emerging as ingredients bowl of the future. Additionally, growing urbanization coupled with industrialization and changing lifestyles have led to growing demand for convenient food that offers health benefits, over and above the basic nutritional benefits of the foodstuff. There are nearly 10 to 15 broad classes of ingredients that include the very basic ingredients as well as certain value added ingredients that have niche applications. Key ingredients are preservatives, flavours, colours, hydrocolloids/stabilizers, emulsifiers, artificial sweeteners and value added health food ingredients such as omega-3-fatty acids prebiotics, probiotics etc. Until recently, there has been limited research into functional foods in meats, while functional foods in the dairy sector have been developed to a high degree. But meat is less allergenic than many other foods and much more research into the development and marketing of novel functional meat products is required. Such meat products would open up a new market for the meat industry. Nutraceutical and functional food industry is a very vibrant industry today with the claims and a clear mandate of health, wellness and prevention of diseases as one of its main goals.

All these methods of utilization and the conversion to useful energies depend on the climate, population density of the area and the basic infrastructure. It is important to work out the market for the products which are produced.
 
Bio-waste management: It needs to take from small actions to the ambitious ones. European Commission proposes to use wastes which could make up to 25% of total energy consumption by 2020. They propose to have directives for the promotion of renewable electricity (Directive 2001/77/EC) and biofuels (Directive 2003/30/EC). The waste production in Europe has gone upto 2 kg per capita per day. Recycling rates are also rising (European Commission, 2017). The Member states must develop a national action plan and outline the national policies to develop existing biomass resources and mobilise new biomass resources for different uses. A European project has studied the amount of renewable energy to be used in 2020. According to them it will be around 195 million tons of oil equivalents (Mton) of biomass which is biodegradable part of MSW. This will be 20% of renewable energy target. It has also been estimated that the amount of bio-energy from the MSW will be 20 Mton, which would account for around 7% of all renewable energy in 2020. This may be available after composting and anaerobic digestion (Atanasiu, 2010).

Introduction

COVID-19, a worldwide pandemic, addresses a deflationary stun for the worldwide economy. The outbreak of coronavirus has had a significant impact on public health worldwide and all stages of various industries’ supply chain and value chain. The 2019 novel coronavirus (2019-nCoV) or the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is rapidly spreading from its origin in Wuhan City of Hubei Province of China to the rest of the world. The infection began in bats and was communicated to people by inhalation or contact with infected droplets, and its infection time frame goes from 2 to 14 days. Primary manifestations in hospitalized patients with COVID-19 include fever (98%), cough/hack (76%), and myalgia or weakness (44%). Severe complications include acute respiratory distress syndrome (ARDS), RNAemia, acute cardiac injury, and multiple organ failure. However, exaggerated immune responses may lead to Cytokine Storm. Cytokine storm syndrome includes ARDS, shock, and multi-organ failure (Zheng et al., 2020). Many people are asymptomatic also, and the severity of this disease varies from person to person. The fatality rate is estimated to range from 2 to 3%. Typical/low white cell checks can analyze it with raised C-responsive protein (CRP), periodic modernized tomographic chest examination. The infection spreads quicker than its two predecessors, the SARS-CoV and Middle East respiratory disorder Covid (MERS-CoV); however, it has lower casualty. The worldwide effect of this new scourge is yet questionable (Singhal, T. (2020).

Abstract

The present study was conducted to develop ready to eat extruded snack food based on germinated flour of wheat, Bengal gram and green gram. A Central Composite Rotatable Design (CCRD) for five variables at five levels was used for experimental combinations and optimization of the process parameters. Experimental design with green gram flour (5 to 20%) and bengal gram flour (1535%) in wheat flour, moisture content (14-18%), screw speed (200-300 rpm) and barrel temperature (126-134°C) as independent variables having 32 different combinations of snack formulations that were studied using response surface methodology to investigate the effect of these variables on product responses (Lateral expansion, bulk density, Water absorption index, water solubility index and sensory characteristics). Sensory analysis was carried out of all extrudates for texture, color and overall acceptability. Multiple regression equations were obtained to describe the effects of each variable on product responses. The optimum operating conditions for development of germinated wheat, green gram and Bengal gram flour extrudate were 132°C of barrel temperature, 275 rpm of screw speed, 17 % offeed moisture, 6.5% of green gram flour and 23.1% of Bengal gram flour. The responses predicted by the software for these optimum process conditions resulted lateral expansion of 169.59%, bulk density, 0.263g/cm³; water solubility index, 19.08; water absoption index, 13.88g/g; and overall acceptability value of 7.38.

Introduction

Whey is the serum or watery part of the milk that remains after separation of curd that result from the acid or proteolytic enzyme mediated co-agulation of milk. It is major by product of dairy industries manufacturing products like channa, paneer, cheese and chakka (Sharma and Bhatia, 1999).The current world production of whey is estimated at about 165 million tones, in that cheese whey accounts for nearly 95 % of total whey. In India near about one million tonne of whey is annually derived, in that major source of whey is from the production of channa, paneer and shrikhand production. This is mostly thrown away as a waste which creates environmental pollution, also in that way about 70, 000 tonnes of Nutritious solids are lost (Puranik, 1999).

11.1 Introduction

Fermented foods are the result of the activity of a few specialized types of micro-organisms among the thousands of species known to mankind. Success of such processes is depended upon the control of environmental conditions ensuring the growth of the desired microbial species and inhibition of others. The fermentation can be broadly defined as the process in which the carbohydrate or like compounds are broken down, under anaerobic or aerobic conditions [171]. The basic role of micro-organisms is to breakdown the organic compounds to get energy for their metabolic activities. From ancient times, people all over the world have developed traditional processes for production of alcoholic beverages (wine) either from natural sugar such as in wine or by degrading the starchy materials (beer). Fruit wines referred to as ‘Soma’ in our ancient scriptures have been part of food of man and were used as medicine, might have originated accidentally (transformation of fruit juice beverages having exhilarating or stimulating properties). Wines are made principally from fruits like grape or extract of other fruits of various types (table wine, sparkling wine, dessert, aperitif or vermouth and pop wines) while the beers are prepared from grains like barley, rice and corn. The principal carbohydrate in grain is starch which can not be fermented directly. This process is brought about by starch splitting enzymes by germinating the grains followed by drying and storage until needed. Distillation of beer produces a variety of liquors (whisky, rum, gin, vodka), while that of wine produces the brandy. Besides, the improvement in the raw material selection, fermentation conditions and techniques, a lot of waste material is generated during fermentation process in the industries. Nevertheless, the food based industries are significant contributors to the economy of the many countries of the world (Fig 1). The global market value of food fermentation based industries is estimated to be around 250 million US dollars. Interestingly, more than 10% of this accounts for alcoholic beverages (Fig 2) with projected increase of US$ 27 billions in 1989 to 40 billions in 1990 [93,123,123,129].

1. INTRODUCTION

Wild fruits are highly nutritious and contain vitamins, carbohydrates, protein and minerals in higher quantity than majority of other common cultivated fruits. They are also a rich source of several bioactive substances, compared to the cultivated fruits. In India,these wild fruit trees grow abundantly across an altitudinal gradient of Himalaya and the majority of them bear fruits during summer. Fruit varieties are consumed by the local inhabitants of the region. At the same time, there are numerous under exploited species of wild fruits having high potential for exploitation viz., Bael (Aegle marmelos CL.), Berberis asiatica DC, Seabuckthorn (Hippophae sp.,) Rubus sp., Prunus armeniaca L., Karonda (Carissa carandas L.) Bitter Almond (Prunus amygdalus Batsch Smith), Feijoa sp. Among the wild fruits, Hippophae sp.was found to be economically efficient, followed by Aegle marmelos, Rubus ellipticus Smith, respectively. Wild apricot (Prunus armeniaca L.), a semi-domesticated and less utilized fruit of the higher Himalaya, provides better economic returns on an annual basis. Attempts have been made to utilize these wild fruits as a source of income, particularly for poor rural inhabitants and unemployed youths of the region by making a variety of edible products such as jam, jelly, juice, squash, sauce, wine etc. Here in this article, production of wine, vermouth and brandy from wild fruits would be focused. But before discussing preparation of wine and brandy in detail, we shall be describing the general process of wine and brandy making first, then the products from the specific wild fruits.

Vacreation: The pasteurization of the milk or cream under reduced pressure by direct steam is called vacreation. This process removes feed and other volatile flavors from cream and to pasteurize it for butter making. This is also called vacuum pasteurization (Plate 623).

Vacuum: The state of negative pressure. It is equal to atmospheric pressure minus absolute pressure.

Vacuum cooling: A technique of cooling vegetable (leafy vegetables, asparagus, brussels sprouts) having a high surface to volume ratio; rapidly and uniformly by boiling off some of their water at 10C and at low pressure (5 mm of Hg) into a sealed container. The produce is cooled by evaporation of water from the tissue surface and is more rapid than hydro cooling (Plate 624).

Vacuum drier: A drier used to dry heat sensitive products where low pressure lowers the temperature, helps to retain natural flavour and minimizes oxidation and browning is called vacuum drier (Plate 625).

Abstract

Drying is an age old practice of food preservation. Removal of moisture from the food materials is usually carried out at atmospheric pressure and elevated temperature. In the presence of oxygen, drying can cause oxidation of some compounds leading to quality deterioration. Drying at higher temperature adds to the losses and can be responsible for enzymatic and non enzymatic browning, loss of aroma, nutrients, antioxidants, pigments etc. On the other hand, drying under sub atmospheric pressure helps in retaining the themosensitive compounds present in natural foods as drying can be accomplished in oxygen free environment. Under vacuum, evaporation of moisture can be possible at lower temperatures.

Lanolin, commonly known as Wool grease is primarily a lipid secretion from sebaceous glands of wool bearing animals. The role of Lanolin in nature is to protect wool and skin of animal from climate and the environment. It is an excellent emollient, self-emulsifying and dermatological safe for skin applications. Lanolin is a complex matrix since it is a mixture of high molecularweight esters of fatty acids with fatty alcohols, sterols, tri-terpene alcohols; diesters, long-chain alcohols & diols, long-chain fatty acids and hydroxy acids and is therefore difficult for effective matrix clean-up. Because of its water proofing and antimicrobial properties, lanolin is used mainly in cosmetic and pharmaceutical applications.

The increasing global emphasis on sustainability and the circular economy has brought renewed focus to the valorization of agri-biomass and organic waste—the process of converting low-value, often discarded residues into highvalue products. Agricultural biomass, including crop residues such as straw, husks, and stalks, along with organic waste like food scraps, animal manure, and agro-industrial by-products, is both abundant and underutilized, particularly in developing regions. Traditionally, these materials have been disposed of through open burning, landfilling, or natural decomposition, all of which release significant quantities of greenhouse gases and contribute to environmental degradation. However, recent innovations in green technology and material science are transforming these waste streams into valuable resources. Through processes such as pyrolysis, fermentation, and biochemical conversion, agri-biomass and organic waste can now be converted into biochar, bio-based chemicals, and sustainable biomaterials. These products not only mitigate environmental harm but also create new economic opportunities across agriculture, industry, and the renewable energy sector. By leveraging these advancements, societies can significantly reduce waste, lower emissions, and accelerate the transition to a more sustainable and circular bioeconomy.

ABSTRACT

Approximately 30 % of fruits and vegetables are getting wasted each year in country like India. Not only that, there is a huge loss of agro based commodity during industrial processing and will be considered as industry generated waste. Utilization of such unexplored nutrients from agro processing sectors for making a sustainable food system will be a healthy approach to bring food security and nutrition to all of us. With this aim the present work addresses the utilization of jackfruit seeds, an agro-waste, to value added products. Jackfruit seed flour has a great potential in new food formulation along with wheat flour. The 15% (w/w) blending of jackfruit seed flour with wheat flour could be used in bread and the substituted bread is protein and fibre enriched. This attempt in developing such bakery items with blended flours could address the scarcity problem of non-wheat producing countries. Present study also looks into the alternate source of starch from spice processing industries. The nutrient starch could be explored for isolation from a nonconventional source from turmeric processing sector. The isolated starch could also be modified to enhance some of its functional properties and may be utilized in preparing value added product with a better acceptability and nutrition.Thus, the isolation of nutrients and value-added products out of fruits and vegetables and spice-processing waste would be a stepping stone to an initiative to zero hunger.

Dry Flower Products

Dry flowers are aesthetically beautiful and they enhance the décor and liveliness of any room. They bring the fiery warmth and bounty of the season into the home with ease every fall. Much of fall’s beauty lies in the glorious changing colors of autumn leaves. These flowers are dried to use them in a wide range of products. Dried floral products are widely used for decoration and for adding zest to a room. Apart from that they are also used as an essential component of many products. They are widely used to make handmade paper, lampshades, candle holders, jute bags, photo frames, boxes, books, wall quilts, topiary, cards and several gifts. The use of dry flowers in the making of these products enhances the appearance and beauty of these products. They look sophisticated when gifted to someone or used as a décor of your own home.

Abstract

Mango pulp is high in prebiotic dietary fibers vitamin c, polyphenols, carotenoids, vitamins and dietary minerals. Mint leaves are known for its medicinal aromatic and flavorsome qualities. Mint act as powerful antioxidant, protecting the body against the formation of cancerous cells and is rich source of polyphenolic compounds. Tulsi also have antioxidant, adaptogenic, anti-inflammatory, antibacterial and immune-enhancing properties. Honey is natural sweetener and has antiseptic and antibacterial properties. Medicinally, honey is non irritant promote rapid growth of healthy tissue and is useful in purities value, bed spores, skin and intestinal disorder, etc. Keeping in mind the beneficial effects of these raw materials, attempt was made to prepare value added drink from it, which may have medicinal value and good sensory acceptability with objective to prepare and evaluate the recipe for value added green mango-mint-tulsi beverage and to study the shelf life of the developed value added beverage. The formulation prepared with partial substitution of honey was more acceptable. Throughout the storage period, the squash prepared with honey scored more in flavor, taste, mouth-feel and overall acceptability than without honey. The cost of production without including labour, bottling and other overhead charges came out to be Rs. 34.5/L for squash without honey and Rs. 59.0/L for squash without honey.

India is bestowed with diverse agroclimatic zones which aids in the cultivation of large number of commercial flowers like rose, gladiolus, chrysanthemum, tuberose, jasmine, marigolds, orchids, lavender, lily, anthurium, gerbera, potted plants, cut foliages, bedding plants etc. In floriculture trade, value addition takes place at every step to create a novel product and to cater the demand of heterogeneous consumers. In the international floriculture trade, besides floriculture and pot plants, many other value added products include artificial colouring of the flowers to create novelty, aqua-packing for better presentation and attraction, three dimensional window packing of flowers for greater visibility, garland, venis, bouquets, flower arrangements etc.

1. INTRODUCTION

Food processing industries are engaged in production of different types of processed products and generate various types of wastes. These wastes, whether solid or liquid, on one hand are a direct loss to the producer or manufacturer and on the other hand create environmental pollution, if not disposed properly. Therefore, the processors would always like to minimize these wastes. The generation of wastes not only cause economic losses but would also require additional cost for their management and disposal. As a matter of fact, it is often estimated that proper use of efficient machinery and careful handling during various operations can lead to more than 50% reduction in losses.

In general, the wastes from the food processing industries are either not utilized or primarily utilized as animal feed, fertilizer and in preparation of by-products on a limited extent. Many of the wastes such as cuttings and shreds from the fruit and vegetable processing industry can be used as animal feed. Fruit and vegetables wastes can also be used for extraction of starch, pectin, natural colouring matter, fat, essential oils etc. Wheat and maize bran alongwith palm kernel are used for the production of feed for chickens. Various oils and oleoresins having enormous pharmaceutical properties can be obtained from the spice processing industry.

Fermentation is a cheap and energy efficient means of preserving perishable raw materials. It commonly does not require any sophisticated equipment, neither is the storage of fermented products a big issue. Fermented foods play an important role in providing food security, enhancing livelihoods and improving the nutrition and social well being of millions of people around the world, particularly the marginalised and vulnerable population across the developing countries.

Orchids comprise the largest family of flowering plants with 25,000 to 35000  species belonging to 600-800 genera. They are prized for their incredible diversity in the size, shape and colour and attractiveness of their  flowers and high keeping qualities even upto 10 weeks. In the international trade, among   top ten cut flowers, orchids rank the sixth position and among orchids Cymbidium ranks the first position and in floricultural crops it accounts for 3% of the total cut flower production. In India, it comprises 140 genera and 1300 species which grow upto an elevation of 5000m. Indian terrestrials are located in humus rich moist earth under tree shades in North Western India.  Western Ghats harbour the small flowered orchids. Epiphytic orchids are common in North eastern India which grow upto an elevation of 2000m from sea level.

Several products of fruits and vegetables are prepared on commercial and home scale. Products development from fruits and vegetables is the best way to utilize excess produces and save them from post harvest losses..

Value Addition

This is the process of improving the value of a commodity through processing by changing its form, increasing its shelf life or better presentation like packaging. Value addition can be done through the ways.

Annual plants complete their life cycle within the space of one year are called annuals. They have multipurpose uses like as cut flowers, a wealth of bloom through out the summer and early autumn months; as component in herbaceous border, to make colour scheme, for window boxes and porches, as pot plants in green house or conservatory, for edging, for drying and herbal medicines.

Aquatic plants are essential to maintain water balance. They also keep out the dreaded algal bloom. Aquatic plants absorb the minerals and carbon dioxide in the water. Pond plants are classified into four groups: oxygenators, marginals, floaters and aquatic. Oxygenators such as buttercup and water violet supply lots of oxygen in the water. Marginals are ornamental pond plants and planted in pots or baskets in the edge of the ponds to provide space for fishes or frogs, e.g., Primula. Floaters like water hyacinth help in keeping algae at bay and also provide enough cover for tadpoles or small fish.

Bulbous plants are herbaceous perennial or biennial ornamental plants which produce fleshy storage organs including true bulbs, corms, tubers, rhizomes and tuberous roots. These underground organs have capacity to store moisture and nutrients are utilized by bulbous plants to survive winter or other adverse conditions such as summer drought and heat in a dormant state.

Cacti

Cacti belong to the family Cactaceae comprising of 130 genera and 2000 species and bear a complex organ, a cushion like structure spirally arranged over the stem called ‘areoles’ from which spines, hairs, flowers and shoots develop. In tribe, Pereskieae, the plants are leafy bushes or shrubby and characterized by areoles on the stem and by the typical flower borne in clusters, e.g. Maihuenia, Pereskia and Rhodocactus.

Rose
Rose is a perennial erect shrub, climber or trailing plant  belonging to the genus Rosa within the  family Rosaceae. The plants bear large and showy flowers of white, yellow, red, pink, orange and various shades. Most of the species are native to Asia.

Valuable Genetic Resources

Shrubs are group of plants having woody stems and multi-branching from the base of the plant. These plants are useful to build up the framework of the planting scheme for screens, ground covers, flowers and hedges. They vary in blooming time, colour, size, growth habit, fragrance as well as situations.

Herbaceous perennial flowers complete their life cycle in more than a year and usually bloom during a specific time period every year during the growing season. These flowers are hardy and herbaceous. They are popular in their dried form for beautiful and exotic dried flower arrangements. Besides, perennials are used as ground covers, mixed with annuals, grown as potted plants and used as accents or specimen plants. Some important perennial flowers are Baby’s Breath, Bells of Ireland, Blue Globe Thistle, Carnation Flowers, Daisy Flowers, Flax, Hibiscus, Hollyhock, Iris, Ladys Mantle,Larkspur, Lavender, Lily Flower, Monkshood, Pearl Everlasting, Rose Flowers, Statice, Sunflower, Yarrow.

Foliage or house plants are mostly those with attractive foliages or flowers and are able to survive and grow under indoor conditions. They are mostly used for interior decoration or interior plantscaping. Foliage plants of world’s importance include Aglaonema, Dieffenbachia, Dracena, Epidendrum, Ficus, Peperomia, Philodendron, Sansevieria, Syngonium, Schfflera, ferns, Anthurium, Codiaeum. Florida shares more than 55% in foliage industry.

India is bestowed with varied agroclimate ranging from mild tropical zones to alpine zones and congenial for several types of ornamental plants in different seasons. Worldwide China and India have large total areas under flower cultivation. Among top ten cut flowers, rose ranks the first position followed by spray chrysanthemum, tulip, lily, gerbera, cymbidium, freesia, chrysanthemum, anthurium, alstroemeria and carnation. In view of rapid changing global competition, diversification into lesser known potential new ornamental plants play key role in fetching premium prices. Most of the potential exotic ornamentals plants have been introduced from Australia, South Africa, Israel, New Zealand and Eastern USA. There are about more than 60 types of new ornamentals reported to be hold potential for commercial importance. All these newly introduced ornamental plants require the following stages of research and development.

Abstract

30 lines were selected from 864 germplasm lines for good biscuit making attributes on the basis of low protein content (<10.5%) and low sedimentation value (<40cc). These lines were further screened by actual baking test and alkaline water retention capacity (AWRC) test keeping the standard prescribed for biscuit making qualities viz., low protein content, low sedimentation value, low AWRC and larger diameter with larger spread ratio of biscuit. AWRC had significant negative correlation with biscuit spread ratio. Positive significant correlation was found between biscuit spread ratio and biscuit diameter. On the basis of above findings, it may be recommended that low protein content, low sedimentation value, low AWRC may be used as criteria for better biscuit making i.e. increase biscuit spread ratio and biscuit diameter. So wheat-breeding programme has opened up new opportunities for the end use quality product and wheat based food industry. Hence there is an urgent need for qualitative analysis of desired traits in wheat towards enhanced value addition and thereby an attempted has been made to identify suitable genotypes possessing good biscuit making attributes

ABSTRACT

Microencapsulation is one of the latest technologies used in the food, pharmaceutical, nutraceutical and cosmetic industry where it is used for maintaining the stability of the food ingredients and slow release of the active food ingredients. For many decades the encapsulation technique was used in the pharmaceutical industries, but from last three decades it has been effectively used in the food industries showing enhanced results in flavour masking and retention of bio- active components present in the food. The production of the microcapsules can be achieved by the various process technologies. The process technologies have been reviewed in this paper such as spray drying, extrusion, spray chilling, emulsions, fluidized bed coating, freeze drying, molecular inclusion, crystallization, co-acervation etc. the encapsulation of food materials has shown a promising result in the newly growing food processing industries. Some of the recent developments in the microencapsulation viz. sweetener immobilization, controlled release and the carrier materials are also being presented in the reviewed paper.

Introduction

While Indian agriculture has evolved to provide food to our ever growing population, nutritional security had remained a distant dream. Vegetables, an important component of a healthy diet, are rich source of nutraceuticals such as flavonoids, carotenoids, vitamins, anthocyanins, polyphenolics etc. Such constituents provide health benefits of disease prevention through antioxidant activity and reduced disease risks. Since perishable food commodities and light sensitive nutraceuticals have a specific shelf life, these run the risk of getting spoilt beyond a specific time. Excessive quantities of these must therefore, be processed and converted into value added products with improved shelf life and nutrition value after fortification with nutraceuticals. Nutraceuticals are also referred to by different terminologies like functional foods, fusion foods, dietary supplements, designer foods etc. Nutraceutical products include food supplements, dietary supplements, value-added food products, processed food commodities as well as non-food supplements such as tablets, soft gels, capsules etc. A survey related to nutraceutical rich vegetables has revealed that farmers are growing only the conventional vegetables and there is little awareness about the use of nutraceutical rich vegetables.

Vegetables are rich sources of important phytochemicals, which provide essential nutrients and enhance the body’s ability to prevent and fight disease. There is a multitude of phytochemicals, in unique combinations, in different vegetables, and each functions differently in the body as anti-oxidant, as anti-allergenic, as anti-carcinogenic, as anti-inflammatory, as anti-viral, and/or anti-proliferative. Being of natural origin, some of the phytochemical pigments are increasingly sought after as food colorants. Some of the nutraceutical rich vegetable crops include red and black carrot, beet root, tomato, chilli, and broccoli.

INTRODUCTION

Vegetables and fruits have many similarities with respect to their composition, methods of cultivation and harvesting, storage properties and processing. In fact many vegetables are considered fruits in the true botanical sense. But the difference between the two is that vegetables are derived from various parts of plants e.g. roots, leaves, stems, buds and so on whereas, fruits are the mature ovaries of plants with their seeds. The edible position of most fruits is the freshly part of the pericap or vessel surrounding the seeds. The other difference between the two is that those plant items that are generally eaten with the main course of a meal are often considered to be vegetables, whereas those that are eaten alone or as a dessert are considered as fruits. This is the distinction made by food processors, certain marketing laws, and the consuming publics.

4.1. Origin and distribution

• Indigenous to Indian sub-continent.

• Native of Tropical Asia and introduced into tropics of both hemispheres.

4.2. Economic importance

• Economic part-roots up to 30-40 cm, cooling properties

• Maj or constituents - vetivone, vetiverols and vetivernate; obtained by steam distillation of roots

• One of finest oriental perfumes with persistent fragrance.

• Used in manufacture of soaps, cosmetics, perfumery, agarbattis, soft drinks, pan masala etc.

• Acts as excellent fixatives for volatile compounds.

A dilute solution of acetic acid produced by a two-stage fermentation process in the first stage, fermentable sugars is converted into ethanol by the action of yeasts and in the second stage, bacteria of the genus Acetobacter oxidize the ethanol to acetic acid.

Vinegar is a liquid produced from the fermentation of ethanol in a process that yields its key ingredient, acetic acid. The acetic acid concentration ranges typically from 4 to 8 percent by volume for table vinegar (typically 5%) and higher concentrations for pickling (up to 18%). Natural vinegars also contain smaller amounts of tartaric acid, citric acid, and other acids.

A five-kingdom classification system fails to classify viruses because they are not considered to be living. They neither reproduce independently nor utilize energy

General properties of virus

Viruses differ fundamentally from other classes of microorganism in that:

1.They are ultramicroscopic disease-producing entities.

2.They are simple in structure, basically composed of nucleic acid wrapped up in a protein coat.

3.The genome nucleic acid is either DNA or RNA , either single stranded or double stranded, but never both

4.Viruses have no metabolic activity of their own and lack enzyme systems and other constituents fundamental for independent growth and multiplication.

5.They do not posses ribosomes, nor transfer RNA and enzymes required for synthesis of nucleic acids and proteins.

6.Viruses are incapable of growth and division.

Franz Holfmeister’s (LT, 1850-1922) definition, “vitamins are substances which are indispensable for the growth and maintenance of the animal organism, which occur both in animal and plants and are present in only small amounts in food”, still holds good, although it has been interpreted in various ways.
