Organic products are grown under a system of agriculture without the use of chemical fertilizers and pesticides with an environmentally and socially responsible approach. This is a method of farming that works at grass root level preserving the reproductive and regenerative capacity of the soil, good plant nutrition, and sound soil management, produces nutritious food rich in vitality which has resistance to diseases. India is bestowed with lot of potential to produce all varieties of organic products due to its various agro climatic conditions. In several parts of the country, the inherited tradition of organic farming is an added advantage. This holds promise for the organic producers to tap the market which is growing steadily in the domestic and export sector.

As per the available statistics, India’s rank 8th in terms of World’s Organic Agricultural land and 1st in terms of total number of producers as per 2020 data (Source: FIBL & IFOAM Year Book, 2020). The APEDA, Ministry of Commerce & Industries, Government of India is implementing the National Programme for Organic Production (NPOP). The programme involves the accreditation of Certification Bodies, standards for organic production, promotion of organic farming and marketing etc. The NPOP standards for production and accreditation system have been recognized by European Commission and Switzerland for unprocessed plant products as equivalent to their country standards. Similarly, USDA has recognized NPOP conformity assessment procedures of accreditation as equivalent to that of NOP of US. With these recognitions, Indian organic products duly certified by the accredited certification bodies of India are accepted by the importing countries. APEDA is also in the process of bilateral equivalence with South Korea, Taiwan, Canada, Japan etc.

The states in the Eastern India where pineapple is grown include West Bengal, Bihar and Odisha. In between this states the ideal condition for pineapple is found in most parts of north Bengal and some north eastern districts of Bihar. West Bengal ranks first in production of pineapple in India (Figure 2).

West Bengal and Bihar

West Bengal ranks ninth in fruit production in India with a total production of 3850.5 thousand ton from 261.02 thousand hectare area (Table 1). Major fruit crops are mango, banana, pineapple, guava, litchi, jackfruit, mandarin, papaya and sapota. A large number of other fruit crops such as Jamun, bael, custard apple, ber, lime, lemon, plum, karonda, aonla, etc. are also grown in various parts of the state (Mitra, 2013). Pineapple is one of the important fruit crop of West Bengal covering an area of 11,410 ha with an average productivity of 30.24 t ha-1(Table 2). The state of West Bengal, having five distinct agro climatic zones, is ideally suited for growing several tropical and subtropical fruits. These agro-climatic zones are:

I. Hill zone II. Terai zone III. Alluvial zone IV. Laterite zone

V. Coastal zone In between these five agro-climatic zones commercially pineapple is grown mostly in Terai zone which is situated at the foot hills. High rainfall, light acidic soils and prolonged monsoon are characteristics of this zone. So the districts are Darjeeling, North Dinajpur, Jalpaiguri and some parts of Alipurduar. Besides terai zone other places where pineapple is grown in small scale or for experimental purpose are described below.

Pineapple botanically called Annanas comosus L. is basically believed to be native to Brazil and thereafter it spread to worldwide over many centuries from its centre of origin. It is a subtropical fruit crops requiring humid climatic conditions with slightly acidic soils for its favourable growth and development. In India it reached around 1548AD. The juicy fruits are good source of Vit-A, B and C along with micronutrient Calcium. A single unit of pineapple fruits is reported to contain moisture-85%, sugar-13per cent, protein-0.6%,mineral mater-0.05%, fibre 0.3%, Ca-0.02%, phosphorus- 0.01per cent iron- 0.09.0 acids- 0.6%, Vit-A (60IU/100g), riboflavin (120mg/100g) and Vitamin-C (63mg/100g). All parts of pineapple are utilizable from delicacy of fruit for table purpose to making fabric Pina in some country like Philippine. Indeed the dry waste after juice extraction can also be used as good feed for cattle. India is such a country blessed with diverse agro climatic zones and eight classification of agro-climatic zone has been officially classified for suitability of different fruit crops based on their climatic requirement. One of those classifications is North Eastern subtropical Humid Zones which comprises of eight states namely Assam, Arunachal Pradesh, Manipur, Meghalaya, Nagaland, Sikkim and Tripura. Manipur is a land-locked state situated in the North Eastern Region of India. It is encircled by 9 hill ranges in all sides and has a small valley in the center (the capital Imphal is located in this valley). The State has 352 km long international border with Myanmar to the south-east and 502 km long border with the adjacent states of Nagaland on the North, Cachar district of Assam on the West and Chin Hills (Myanmar) and Mizoram on the South and the South-west and Surma Tract and upper Chindwin of Myanmar on the East. Manipur is next to Assam among NE states in respect of area of Pineapple cultivation. Owing to conducive soil and climate, Manipur is one of the major hubs for pineapple cultivation among the north east states where because of its popularity, it has surplus in area and production compare to other fruit crops in the state.

Pineapple [Ananas comosus (L.) Merr.] is one of the most importanttropical fruit belonging to the family Bromeliaceae and is native to Brazil. It is cultivated in High rainfall and humid coastal regions of peninsular India and Hilly areas of North eastern states. In India, pineapple is commercially cultivated in the states like West Bengal, Assam, Karnataka, Bihar, Tripura, Kerala, Nagaland, Goa, Arunachal Pradesh, Manipur and Meghalaya on large scale whereas on small scale in the states like Gujarat, Andhra Pradesh, Maharashtra, Tamil Nadu, Orissa and Uttar Pradesh etc. It is popularly known as ‘Ananas’ in India and has lot of health benefits due to the presence of a proteolytic enzyme called bromelin, which is used to tenderize meat (Coppensd’ Eeckenbrugge, 2011). It acts as antiamoebic, arbortifacient and also used in correction of stomach disorders (Leal and Coppensd’ Eeckenbrugge, 1996). It is consumed both fresh and processed but mostly as fresh (70%) (Loeillet, 1997). Portuguese are the first people to introduce pineapple to India. The greenhouse cultivation of pineapple was first started in 1500s by Europeans, which led to the varieties like Smooth Cayenne and Queen and transported to all tropical and subtropical regions of the world (Collins, 1951). Due to its ease in transport of its propagules and high tolerance to drought, pineapple cultivation has spread worldwide. But due to its short shelf life, in temperate regions it is consumed more as processed food. The first commercial product made out of pineapple is jams and sweets (Thevet, 1957).

Introduction
Sterilization of culture media, containers, and instruments is crucial in bacteriological work to ensure the isolation and maintenance of pure cultures. Sterilization and sanitization are essential processes in a microbiology lab to prevent contamination and ensure accurate results. Sterilization refers to the complete elimination of all microorganisms, including bacteria, fungi, viruses, and spores, using methods like autoclaving, dry heat, filtration, and chemical agents. Sanitization, on the other hand, reduces microbial load to a safe level through cleaning and disinfection using alcohols, detergents, and UV light. These practices maintain aseptic conditions, protect lab personnel, and preserve sample integrity. Proper sterilization and sanitization are fundamental to microbiological research, clinical diagnostics, and industrial applications, ensuring reliable and reproducible experimental outcomes.
Preparations for Sterilization Before sterilization, cleaned and dried test tubes and flasks should be carefully plugged with clean, non-absorbent cotton. Pipettes should also be plugged at
the mouth end, and the plugs should remain in place during use to minimize oral contamination. Cotton plugs provide sufficient ventilation for bacterial growth while preventing external contamination.

Sterilization is defined as the process by which an article, surface or medium is freed of all living microorganisms either in the vegetative or spore state.

Disinfection means the destruction or removal of all pathogenic organisms, or organisms capable of giving rise to infection. Chemical disinfectants which can be safely applied to skin or mucous membrane and are used to prevent infection by inhibiting the growth of bacteria are called antiseptics.

Five main methods are used for sterilization. 1. Red heat (flaming) 2. Dry heat (hot air) 3. Moist heat 4. Filtration 5. Radiation.

The killing effect of dry heat is due to protein denaturation, oxidative damage and toxic effect of elevated levels of electrolytes. The lethal effect of moist heat is due to the denaturation and coagulation of protein. In the case of spore, steam condenses on it, increasing its water content with ultimate hydrolysis and breakdown of the bacterial protein.

Sterilization is a thermal process aimed at destroying all microorganisms and microbial spores in milk, ensuring the product is microbiologically safe and shelf-stable at room temperature for extended periods. It is primarily used in the production of sterilized milk and evaporated milk, with typical conditions involving heating at 116°C for 15 minutes. This process kills all microorganisms and also inactivates all milk enzymes, including plasmin, which might otherwise contribute to spoilage during storage. However, enzymes produced by psychrotrophic bacteria should not be present in raw milk, as they are highly heat-stable and may remain active even after sterilization. Sterilized milk can be stored at room temperature for longer period. Sterilization kills all microorganisms and inactivates all microbial spores that may germinate under the storage conditions of the product in the market.
The Food Safety and Standards Authority of India (FSSAI) define “sterilization” in relation to milk and milk products as the process of heating the product in a sealed container continuously to at least 115°C for 15 minutes. This treatment ensures that the milk can be preserved at room temperature for a period of not less than 30 days.
In-bottle sterilised milk is a shelf-stable dairy product produced by sealing milk in glass bottles and subjecting it to high-temperature heat treatment. Typically, the milk is heated to temperatures ranging from 110°C to 121°C for 15 to 30 minutes. This process effectively destroys all vegetative microorganisms and bacterial spores, making the milk microbiologically safe and extending its shelf life up to 6–9 months without refrigeration. The heating is usually done in batch retorts or autoclaves after the milk has been bottled and sealed. Although the process ensures safety, it often leads to a slight cooked flavour and some nutritional losses, particularly in heat-sensitive vitamins such as vitamin B1 and vitamin C.

1. Introduction

 Mushrooms have been part of man’s diet for centuries (Rajarathnam and Shashirekha, 2003). Mushrooms grow on wide range of agro-residues, biodegrade and biotransform them into edible fruiting bodies (Rajarathnam and Zakia Bano, 1988a; 1988b; 1990; Zakia Bano and Rajarathnam, 1988; Zakia Bano et al., 1993; Rajarathnam et al., 1998). Their post-harvest life is very ephemeral at room temperature (Rajarathnam et al., 1983) due to delicate flavor (Rajarathnam et al., 1990) and high moisture content, with a range of chemical constituents (Zakia Bano and Rajarathnam, 1986; 1982; 1988; Rajarathnam and Zakia Bano, 1990; Rajarathnam et al., 1983; 1992). Since, they contain large quantities of water and therefore suffer considerable weight loss during transportation and storage, causes serious economic losses, due to reductions in weight and quality (Gray, 1970). When the supply of water, organic substances and minerals are cut off at harvest, the fresh mushroom enters a deterioration or perishable phase. Cap opening and stem elongation are the usual symptoms of senescence constituting visible evidence of deterioration. At room temperature, the shelf-life of mushrooms cannot be for more than 24 h (Rajarathnam et al., 1983). During this period, there are considerable changes in color, texture and taste. In addition, water is continuously being lost as a result of transpiration and respiration. Additional loss occurs from surface cracks and bruises that develop during growth and handling (Salunkhe et al, 1991). Fresh mushrooms are white or light buff, with no dark marks on either the cap or stem. The veil is closed and the gills are not visible. The upper surface of the caps should be strongly convex and stems should be plump rather than elongated. Mushrooms are grown on compost, usually in mushroom houses where the temperature and humidity can be controlled. Eventually after harvest, the mushrooms can never be able to withstand any increase in temperature and decrease in relative humidity. Mushrooms are commercially preferred at the immature stage characterized by closed caps, invisible lamellae, round stipe and light color. Agaricus development is classified into various stages (Table 1). Thus, the concept of physiology of fresh mushrooms being very complicated, bears a great impact on the delicate problem of extending the storage life. The various means and methods studied and adopted by various researchers to aim at extended storage life of fresh produce, underlined by its physical, chemical and biochemical properties and also development of value added products are critically evaluated.

Storage is one of the most important aspects of post harvest handling of fruits and vegetables. The main objective of storage is to extend storage life of fruits and vegetables and increase their period of availability. A substantial quantity of fruits go waste in India due to lack of proper storage facilities. Storage of fruits and vegetables is practiced for various reasons. Proper post harvest handling of fresh horticultural produce helps in extending  period of availability of wide range of  fruits and vegetables round the year, prevention of seasonal market gluts, orderly marketing, better return to grower and  preservation of  nutritional qualities. The   long  term  storage  of  fruits  and  vegetables is expensive and requires high level of technical  knowledge of crop. However, an orderly marketing reduces storage period considerably. 

Introduction
• The main objective of food preservation is to avoid food spoilage • So, the underlying principle behind all the meat preservation technique is providing adverse conditions for the growth and survival of the harmful microbials and such adverse conditions may be provided in the from of heat, cold, high level of salt, increasing acidity or removal of water/ oxygen
• Meat can be preserved by many techniques such as drying, heating, low temperature, curing, addition of chemicals or by application of irradiation and high pressure
• Addition of chemical i.e. chemical preservation which is accomplished by smoking is generally done after salting and pickling of meat
Physical changes in stored raw meat
1. Shrinkage
2. Sweating
3. Bloom loss

Storage : It can be defined as keeping the commodity fresh or processed in safe condition with minimum of deteriorative changes for later use.

Reasons of Deterioration During Storage

Abstract

Pulses constitute an important component of the diet and are a major source of protein in vegetarian diet. India has largest area under pulse cultivation and produces a variety of pulses. A large portion of this produce gets spoiled due to insect and fungal attack. A variety of insecticides and fungicides are used for the control of pest during storage. There is an increasing trend towards the reduction in the use of pesticides in storage due to strong demand from consumers to choose food with no pesticide residue, development of insect resistance to pesticides and the impact of pesticides’ use on environment. All these have posed a challenge to refine the existing management procedures of storage and commodity to find the optimal solution. Controlled/ Modified Atmosphere storage offers an alternative to the use of pesticides extends storage life and maintains product quality. The Controlled/Modified Atmosphere is created by altering the composition of the atmosphere in terms of CO2, O2, and N2 concentration. High CO2 produce undesirable conditions for insects and microbes and thus control their activity.

1. INTRODUCTION

To over come the problem of glut of perishables and to regulate the market, storage of such commodities is a 'common' practice. Storage of fruits and vegetables also makes available these commodities in the off-season. Needless to say, storage is a powerful tool in the prevention of postharvest losses and to give remunerative prices to the farmers. The management of temperature and relative humidity are the most important factors determining storage life of horticultural produce. The natural means like ice, cold water, night temperature have been used for long time for protecting food materials from spoilage and these are still common. However, with the development of innovative technologies, it is possible to achieve optimal environments in the insulated stores. All these aspects are discribed in this chapter.

Onion bulbs remain vulnerable to moisture loss, sprouting, rotting and microbial deterioration during extended storage. Traditional structures frequently provide inadequate ventilation and expose produce to fluctuating temperature and humidity. This chapter examines scientific curing and storage technologies, including improved ventilated structures, zero-energy cool chambers, forced-air systems and controlled or modified atmospheres. Renewable-energy and solar-powered facilities are considered for small and marginal farmers. The chapter also discusses value addition through dehydration, powdering, flaking, pickling, paste production and other processed products. Improved storage enables gradual market release and price stabilization, while value addition reduces waste, creates diversified products, enhances shelf life and generates additional income for growers and processors.

Introduction

India is bestowed with huge production of fruits, vegetables, cereals, millets, sugarcane along with meat production, milk production, fish production and poultry. Despite such a huge production in India, owing to perishable nature of these produce around 25-30 per cent of the produce is being lost as post harvest loss. The one important reason for this may be the production of the crops are season specific and during the peak season the production is more while demand for consumption is less. It may be possible to cut down losses to great extent, if these produces may be transported from the produce states to those who are not producing due to agro-climatic reasons. So for making transportation of the perishable a successful venture in decreasing post harvest loss, there must be proper storage facilities both at producing site as well as marketing place. The aim of the storages must be to keep the produce in saleable condition during entire storage periods. Some products are stored for short period whereas fresh fruits, vegetables require cold storage. Foods before keeping into the storage room need some pre-storage treatments for better results.

Proper marketing of perishable commodities such as fruit and vegetables often requires some storage to balance day-to-day fluctuation between harvest and sale or for long term storage. Storage of horticulture produce is attempeted with a view to extend period of availability. Storage controls shelf life of produce by controlling rate of respiration, transpiration, ripening and biochemical changes all of which are responsible for shelf decomposition/deterioration of produce. Further, different types of storage have different attributes in minimizing microbial infection and thus add to better storability of produce.

SYNOPSIS

Urban and rural agriculture are different entities in terms of stakeholder involvement and enabling environment for farming but they are dialectically interlinked in providing food and nutrition security of any country. Urban agriculture is more suitable on the production of nutritious crops, while rural agriculture’s first priority is to produce more food from staple. Attaining nutrition security is more complex than it is previously thought. However, while existing systems of production should continue at field levels by developing more nutritionally rich cropping patterns, its integration with farmers’ farming systems remains more important.

Introduction

Enterprise management involves a combination of tools, strategies, and processes that work together to form a cohesive plan and framework supporting overall operations. The key is ensuring that these elements are interconnected, which enables the smooth flow of information and minimizes redundancies.

Core business functions such as human resources and supply chain management often operate in isolation. However, this separation can slow down business operations, create unnecessary obstacles, and lead to loss of revenue or customers.

By viewing each business area as interconnected, these silos can be eliminated, leading to more efficient operations. For instance, a well-functioning human resources team can hire the right talent, which, in turn, strengthens marketing and sales efforts. As sales grow, revenue increases, enabling further improvements in logistics operations.

Abstract

The control of micronutrient deficiency is a realizable goal, notwithstanding the magnitude of the task, challenges and constraints that need to be resolved. Since wheat products particularly maida and atta form the major raw material in widely consumed food items like chapati, bread and biscuit. Fortification of flour as followed in many other countries could be an important strategy to help realize this goal. The technology of flour fortification is effective and cost affordable. Effective flour fortification program would require collaboration between scientific community, governmental and non-governmental agencies, and industry and consumer groups.

Abstract

‘Made in India’ is no more a sign of poor quality. However, in the field of food grain exports, India is still lacking the required determination. The Indian food grains get rejected in the International market because of its out-dated post harvest technology (PHT). The Food Corporation of India (FCI) is the nodal national agency for the procurement, storage, processing and transporting of food grains, and their further distribution through the Public Distribution System (PDS). The government fixes the procurement price as well as the distribution price of the food grains, and the FCI has to accept it. The government compensates the resulting loss through subsidy. The government, through FCI, must encourage cultivation and marketing of premium quality food grains, by offering suitable incentives to farmers. The cost of marketing, storage and transporting of food grains can be considerably reduced with simultaneous improvement in quality of the end product, if the prevailing bag handling is replaced by bulk handling, storage, and transportation. However this needs closer coordination between various departments of the Ministry of Food and Ministry of Railways. The President of India revealed his vision to make India a developed country by the year 2020. To achieve this, the current post harvest losses to the tune of 10 percent must be reduced to 2 percent. This is possible if the government takes bold political decision supported by equally firm and time-bound necessary
