Principles
The quality of foods can be defined as the ‘composite’ of those ‘characteristics’ that differentiate individual unit of a product and have significance in determining the degree of acceptability of that unit by the consumer. The overall quality refers to technological, physiological, chemical, microbiological, nutritional; and sensory parameters to achieve the wholesome food. Sensory quality attributes such as taste, colour, texture, flavour and overall quality of any food products were evaluated by 9- point Hedonic rating test is used for the purpose of evaluation. This test measures the consumer’s acceptability.

Principle
Jam: Jam is a product made by boiling the fruit pulp with a sufficient quantity of sugar to reasonable consistency, firm enough to hold fruit tissues in position. Apple, pear, sapota, apricot, carrot etc. are used for preparation of fruit jam. Jam contains 0.5-0.6 % acid and invert sugar should not be more than 40 %.
Total soluble solids (TSS)
The TSS value is defined as the amount of sugar and soluble minerals present in fruits and vegetables. A refractometer is based on the principle of total refraction. This is done by placing a few drops of distilled water on the prism in the specimen chamber of the back the cover. The distilled water reading should be zero. If it is not so, it should be set to zero with the scale correction knob. The specimen chamber is now cleaned with muslin cloth or tissue paper. For determining the TSS, a drop of sample (jam, juice and syrup, etc.) is placed on the prism and the percentage of dry substance in it read directly on scale in refractometer.

Principle
Jelly: Jelly is a semi-solid product prepared by boiling a clear, strained solution of pectin containing fruit extract, free from pulp, after the addition of sugar and acid. A perfect jelly should be transparent, well set, but not too stiff, and should have the original flavour of the fruit. It should be of attractive colour and keep its shape when removed from the mould. Pectin (0.5-1.0%), acid (0.5-0.75%), sugar (65%), and water are the four essential ingredients. Pectin test and determination of end-point of jelly formation are very important for the quality of the jelly. Some recipes for jelly making are given below:

Objective: Development of RTS beverage from seasonal fruits.
Material required
Fruit, juicer-mixer-grinder, preservatives, sugar, refractometer, pan and knife etc.
Principle
Ready To Serve(RTS): This a type of fruit beverage which contain at least 10% fruit juice and 10% total soluble solid besides about 0.3% acid. This is not diluted before serving.
Before undertaking the preparation of beverage, it is necessary to know techniques of extraction of pulp/juice from various fruits used for RTS.

Principle
Squash: A fruit juice squash essentially consists of juice containing moderate quantity of fruit pulp to which cane sugar is added for sweetening e.g. orange squash, plum squash. This is a type of fruit beverage containing at least 25 percent fruit juice/pulp and 40-50 percent total soluble solids, commercially. It also contains about 1.0 percent acid and 350 ppm SO2 or 600 ppm sodium benzoate. It is diluted before serving.
Mango, orange and pineapple are used for making squash commercially. It can also be prepared from lemon, lime, guava, pear, apricot, muskmelon, papaya etc., using potassium metabisulphate (KMS) as preservative, or from jamun, passion fruit, peach, phalsa, mulberry, raspberry, straw berry, grapefruit etc., with sodium benzoate as preservative.

Principle
Nectar: The term ‘fruit nectar’ is used to designate pulpy fruit juice blended with sugar syrup and citric acid to produce a ready-to-drink beverage. In this fruit beverage contains at least 20% juice/pulp and 15% total soluble solid and also 0.3% acid. It is not diluted before serving. Many fruit juices are either too acidic or strongly flavoured; these cannot be pleasant without dilution of blending or both. These strong, tart juices are delicious after dilution with thin syrup or blend juice e.g. apricot, guava and plum juice. Out of the tropical fruits, nectars made from banana, guava, mango and papaya are quite popular. The product is sealed in container or glass bottles and processed by heat to prevent spoilage. The fruit ingredients may be puree, pulp, juice or concentrated equivalent to 40 percent of the finished products. Apples, cherries and pineapples are used in combination with others fruits. The sweeteners are sugar, invert sugar syrup, dried corn syrup, glucose syrup and the optional ingredients are lemon juice, citric, malic and fumaric acids as acidifier and ascorbic acid as antioxidants (150 ppm) can be used.

Principle
Chutney and sauces are important food products prepared both in homes as well as commercially in India. They improve the digestion and are good appetizers. Tomatoes are a good source of vitamin C. Fresh tomatoes are very refreshing and appetizing but can not be stored for a long period. Often they are sold at distress prices during the peak harvest season and nearly 25% of the produce is spoiled due to mishandling and improper processing facilities. Such losses can be reduced by converting fresh tomatoes in to delicious product like paste, puree, juice, ketchup/sauce and powder. Generally, the sugar content in ketchup/sauce varies from 10-26%. The salt content of the product should be 1.3 to 3.4%. Good quality vinegar is essential for the preparation of high quality sauce/ketch up. It should contain 5.0-5.5% acetic acid or glacial acetic acid (100% acetic acid) and should be added when the product has thickened sufficiently. Tomato sauce/ketchup generally contains 1.25-1.50% acetic acid. In order to increase the viscosity and prevent the separation of pulp from clear juice, pectin can be added to extent of 0.1-0.2% pectin by weight of the finished product. Add 0.025% sodium benzoate as preservative to the product before bottling and then pasteurize.

Principle
Pickle is an edible product preserved and flavoured in a solution of common salt and vinegar. Spices and oil are also added. They add to palatability of a meal, aid in digestion and are good appetizers too. Pickles are prepared from fruit and vegetables like cauliflower, reddish, carrot, green chili, turnip, cabbage, onion, mango, jackfruit, aonla and lemon etc. Commercial preservation of many pickle relied upon conversion of fermentable carbohydrates by lactic acid bacteria to organic acids during bulk storage and/or the addition of sufficient amount of sugar, vinegar and other ingredients to the fully cured and packed products to preclude any microbial growth. Organic acids, oil, salt and spices all have antimicrobial properties at suitable concentration especially in combination which preserves the pickles. Pickles in brine such as or after fermentation however, need some amount of preservative or pasteurization to prevent the spoilage.

Objective: Development of Sugarcane Vinegar.
Principle: Sugarcane is one of the main crops worldwide, and it has an important impact on environmental issues. Sugarcane is used in daily routine life in many ways like as vinegar, jiggery, juices etc. In India sugarcane crop is best cultivated in the west U.P. Sugarcane original vinegar drink with high nutritional quality was produced from fresh sugarcane juice using the yeast culture and acetic acid bacteria by fermentation techniques such as submerged alcoholic fermentation followed by acetic fermentation at room temperature. Refined sugarcane is the primary product of sugarcane juice, during its processing; various other valuable products are also obtained in an unrefined form such as brown sugar, molasses, jaggery and vinegar. Sugarcane juice is widely used in the treatment of jaundice, hemorrhage, dysuria, and other urinary disease. Nowadays sugarcane vinegar is also used in Indian kitchens commonly in pickles, salads, etc. Vinegar is extremely useful for human health including antimicrobial activity, blood pressure reduction, antioxidant activity, reduction in the effects of diabetes, and prevention of cardiovascular disease. Vinegar can be made from any carbohydrate source, amylaceous, or sugary substrate through two successive fermentations: alcoholic fermentation, which is carried out by means of yeasts, and acetic fermentation, with acetic bacteria as the protagonist.

Objective: Development of Salted Banana chips.
Banana is the second most significant natural product harvest of India close to mango. It is accessible round the year and due as it would prefer, nutritive and the rape tic worth. It is most loved product of all classes of individuals. It is a rich wellspring of sugar and nutrients especially nutrient B. Banana assists with diminishing the danger of heart illnesses. Banana is a famous organic product because of its low cost and high nutritive worth. Banana contains about 20% sugar and sensible measure of Vitamins A, B and C. This is considered to be a rich source producing food. It is consumed in several forms and among many worth added arrangements, Banana Chips is viewed as the main thing. Seared banana chips are typically delivered from under-ready banana cuts southern style in sunflower oil or coconut oil. These chips are dry (like potato chips), contain about 4% water (table), and can be salted, spiced, glossed over or jaggery covered. Some of the time banana enhancing is added.

Modern agriculture faces unprecedented challenges due to climate change, unsustainable farming practices, and declining soil health. In response, nanoparticle-bioinoculants (nano-bioinoculants) have emerged as a promising innovation that integrates nanotechnology with microbial inoculants to enhance plant productivity and sustainability. Conventional agriculture contributes significantly to greenhouse gas emissions, degrades microbial diversity, and compromises ecological balance. Beneficial microbes, known as bioinoculants, play a vital role in improving plant health through nutrient cycling, hormone production, and disease suppression. However, their field performance is often limited by environmental instability and low survival rates. Nanotechnology provides a solution by enabling the encapsulation of bioinoculants within nanoparticles, enhancing their stability, targeted delivery, and effectiveness. These nano-scale carriers exhibit high surface-area-to-volume ratios, improved reactivity, and strong adhesion properties, making them ideal for enhancing microbial colonization and activity in the rhizosphere. Additionally, nanoparticles function as nano-fertilizers and nano-pesticides, supporting both plant nutrition and protection against pathogens. Plant-based nanoparticle synthesis further offers an eco-friendly alternative, minimizing ecological and health risks. Studies demonstrated that nano-bioinoculants improve seed germination, stress resilience, photosynthetic activity, and crop yield across various species. They also mitigate abiotic stresses such as drought, salinity, and heavy metal toxicity while promoting systemic resistance against biotic threats. The synergistic combination of nanoparticles and microbial agents enables multifunctional benefits—supporting soil health, reducing chemical dependency, and enhancing agricultural resilience. While challenges remain in understanding

The Asia-Pacific region, particularly the rural areas within CMCs, faces severe climate change impacts, including frequent natural disasters, rising temperatures, and sea-level rise, which threaten agriculture, livelihoods, and food security. Climate- resilient rural development (CRRD) is crucial for mitigating these vulnerabilities, addressing challenges such as agricultural dependency, limited infrastructure, governance gaps, financial constraints, and socio-cultural barriers. Key approaches like climate-smart agriculture, strengthened infrastructure, innovative start-up ecosystems, enhanced access to climate information, and inclusive policies empower rural communities to adapt and thrive. Stakeholders—governments, international organizations, the private sector, and local communities—play complementary roles in driving resilience through policy, funding, technology, and grassroots innovation. Sensitising all stakeholders across countries to mainstream climate change aspects and its impact on livelihoods, among all departments and the information dissemination by these departments to the public and relevant stakeholders regarding the climate change effects needs to be a continuous process. Success stories from Bangladesh

The phases of green revolution and post green revolution of Indian agriculture have assured us of security. We are now producing 354 million tons of food grains and our target is to produce 550 million tons before 2050. This is really an incredible progress for any country dominating with rural and agrarian economy. As on date, the contribution of Indian agriculture to national GDP is 14.7 % but it has to support around 60% of population. While food security has been ensured for 1480 million of population, the issues of malnutrition are standing paramount. It sounds melancholic that India is also sustaining world’s highest count of hungry population close to 51% newborn babies are underweight, 60% of rural women are anaemic, millions are deprived of dedicated safe drinking water. According to FAO, between 702 and 828 million people in the world faced hunger in 2021. Health, hygiene and nutrition are organically linked to each other, in terms of calorie intake of rural women. We are still far below of international standard. Alongside, the hemoglobin level runs below the expected level to indicate that women are runningin a moderate to acute anaemic condition. Around 840 million people are malnourished from insufficient calories. According to Black et al., (2008) nutrition related factors were found to be jointly responsible for around 35% of the child fatalities and 11% of the overall global illness burden in an analysis that took into account co-exposure. Due to poor quality of drinking water, whatever available, the propagation of water born diseases has been endemic and robust. The geo-spatial distribution of hunger and malnutrition indicates that there is location to location variation, gender discrimination, and seasonal variability across the terrain of social-cultural distribution. To make India stronger and swashbuckling we need to refocus on women health, child care and removal of economic discrimination. With acute hunger, mapping, problem of chronic hunger as well, chronic hunger hasbeen reflected through seasonal sickness, broken health and psycho-somatic downfall. Sometimes, poverty has not been the only factor for malnutrition. The other factors for malnutrition can be our wrong belief system, superstition, wrong food habit, and unscientific cooking process. With this background the objectives of the studyhave been spelt out.

7.1. Summary and Conclusion
In its recent move to attaining sustainable development goals through revamping agriculture, ICAR has focused on achieving health and nutritional status through agriculture. In doing this a database and quality information on health, hygiene and nutrition of rural women have become an imperative. Health, hygiene and nutrition are organically connected to each other. One cannot be achieved without the others. The present study has delved into the complex interactions and interrelationship between a set of 13 exogenous variables and another set of 5 consequent variables. A score of 70 rural women have been selected from Bilkumari village of Nadia district by following both random and non-random sampling methods. The stepwise regression analysis analyses for different dependent variables depict that the variables family size (x3), income per year (x4), distance from work place (x6), height (x7), weight (x8), BMI (x9), hip circumference (x12), waist to hip ratio (x13) have been recorded as to exert substantive functional impact on health, hygiene and nutrition of rural women. The factor analysis elicits the fact that instead of 18 exogenous and consequent variables together there have been 4 factors as extracted by calculating the factor loading. These factors are- health ecology, physical status, family ecology and strategic location. Sometimes we are moving in a wrong direction by concluding that if food and calorie are made available for the rural women, the health and nutrition will be achieved. The study has identified that unless proper understanding of health, hygiene, nutrition and health hazards is being build up, no external supply and services can solve the problem of malnutrition and health hazards. Thus, the study has generated huge pool of policy implications after being supported by plethora of far evidences, the output of this empirical research.

6.1 Introduction
The majority of milk demand is urban, while production is restricted to rural areas in nearly all developed dairying countries. Consequently, milk must be collected and transported from production sites in the milk-shed areas to processing and distribution points in cities.
The common systems for collection (assembling) of milk are as follows.
1. Through a cooperative organisation. Established by collective or individual dairy societies. Producers are most advantageous when there are no intermediaries involved in profit labelling.
2. by contractors. Producers receive a diminished return.
3. By independent producers. Convenient for individuals who reside in close proximity to dairy processing facilities.
Note: The milk shed is the geographic region from which a city dairy obtains its fluid milk supply. India is currently contemplating the allocation of specific milk silos to individual dairies in order to facilitate their development.

7.1 Introduction
Certain bacteria are present in milk that is extracted from the udder; they increase in quantity as it is processed further. The optimal temperature range for the proliferation of typical milk bacteria is 20 to 40 degrees Celsius. The formation of unpleasant flavours, increased acidity, and other factors always results in a decline in market quality following the proliferation of bacteria. Prompt chilling to a low temperature is one method of preserving milk. Milk jug Refrigerator: In order to preserve the purity of the milk received at the Dairy/Chilling Centre, it is chilled to 4°C using a milk chiller. Stainless-steel plates comprise the chiller. The process of chilling involves the circulation of chilled water from one side of the plates and milk from the other.
7.2 Methods
1. In can or can immersion method:
The milk is not only cooled, but it also remains cold, necessitating a significantly smaller mechanical refrigeration unit. This is achieved by transporting pails.
Benefits of a surface cooler
• Efficiently and swiftly transfer heat.
• Relatively affordable.
• Additionally, the milk is aerated, which enhances its flavour.

8.1 Introduction
The chemical composition of milk intended for market or milk product manufacturing must be standardised in numerous dairy processes. Standardising milk may necessitate the regulation of a single component (typically fat) while permitting the other components to shift or regulate two or more components concurrently. Definition: The term “standardisation” of milk denotes the process of adjusting the fat and solids-not-fat percentages of milk to the desired value in order to comply with the legal or other requirements.
Objectives of standardization are
1. To ensure that specific milk and dairy products meet legal requirements.
2. To offer a consistent product to the consumer.
3. To guarantee economic efficiency in production.
The volume of milk available for sale is increased by the addition of skim milk, and the separation of cream enables the production of other value-added dairy products, such as butter, table cream, or other high-fat products.

10.1 Introduction
Developed in the 1950s, ultra-high temperature pasteurization typically involves no hold using a temperature range of 135°C to 150°C. Immediate aseptic packaging determines how well UHT heat treatment of milk works.
10.2 Uperization Developed in Switzerland, this is generally known as “ultra – pasteurization”. Milk is heated in this method under direct steam up to 150 °c for a fraction of a second. One is always learning from this. Fore warming milk to 50 °C is the first stage in the uperization process, meant to eliminate most of the dissolved oxygen and volatile off-flavours by vacuum treatment. In the second step, the milk is first preheated to roughly 80–90 °C and then heated on the uperization chamber under high-pressure steam to roughly 150 °C for ½ to ¾ a second. The product moves into an expansion chamber at almost atmospheric pressure after this heating, therefore inducing some evaporation of moisture. The good is then transferred to a chiller and subsequently into a storage chamber.
The advantages of uperization are
• Long keeping quality.
• Removal of feed and other volatile off-flavours:
• Appreciable homogenization effect.
• Reduction in acidity.
• Efficient destruction of microorganisms.
• Effect of uperization on nutritive value and flavour are not greater than that of pasteurization.

11.1 Introduction
“Homogenization” is the method of mechanical treatment producing a stable emulsion of milk fat and milk serum. Homogenizer is the name given to the equipment employed for this aim. The fat globules in milk range in size from 1 to 20 microns; the average is 4 to 6 microns. The homogenizer reduces the size of the fat globules in milk or cream passing through it. The most of them are less than two microns. After homogenization, no cream line develops on milk; churning homogenized cream cannot generate butter grains. Moreover, milk like cream’s viscosity is changing, which increases the resistance the smaller fat globules face. The increase in viscosity is ascribed to the fact that more milk protein will be deposited on the surfaces of more fat lobules. Homogenizing milk changes its clotting characteristics, so the curd made with rennet or pepsin is supposed to be softer. Because lipolytic enzymes adsorbed on the extra surfaces provided by the more numerous tiny fat globules hydroly fat, homogenized milk or cream may become rancid more quickly than untreated goods. The milk or cream must be pasteurized either right before or right after homogenization to prevent these changes. Usually, the milk is homogenized after main heating and then pasteurized. Driven via a small valve against hard surfaces, heated milk is under pressure of 2500 psi and in a second stage under 500 psi. With a 1/10000 inch diameter, the aperture the liquid is driven through is quite small. Mechanical force milk through a narrow passage at high speed produces homogenized milk. This produces a stabile fat emulsion and breaks down the fat globules in milk into considerably smaller ones. Homogenization reduces the inclination of the fat globules to cluster and merge into cream. Milk is an emulsion whereby fat globules are distributed across a constant skim milk phase. Raw milk left to sit will finally cause the fat to climb to the top and form a cream layer. By means of a small opening under high pressure, homogenization mechanically breaks down the fat globules. While increasing their number and surface area, this lowers the average size of the fat globules. Practically speaking, the net effect is a substantially decreased inclination for creaming of fat globules. Three elements contribute to this increased stability of homogenized milk: a decrease in the mean diameter of the fat globules (a factor in Stokes Law), a decrease in the size distribution of the fat globules (causing the speed of rise to be similar for most globules such that they do not tend to cluster during creaming), and an increase in density of the globules (bring them closer to the continuous phase) owing to the adsorption of a protein membrane. < Heat pasteurization also breaks down the cryo-globulin complex, which often clusters fat globules causing them to increase. The homogenizer consists of a high-pressure pump with an adjustable opening based on a minute orifice. High pressure force of fluids through the orifice causes a notable change in the physical characteristics of the treated product and generates a very intimate combination of the fluid components. Annexure- II has a Homogenizer schematic.

15.1 Introduction
Milk is a multifaceted physiological fluid that aids infants in their transition to life outside the womb by supporting digestion and development, as well as providing essential nutrients and bioactive components. It promotes the development of beneficial microflora and enhances the growth of lymphoid tissue. Recent research indicates that the quantity and importance of bioactive compounds in milk may be greater than previously believed. Through research, the distribution and presence of essential components in various animal milks have been analyzed. The consumption of dairy products has been linked to health benefits that mitigate the adverse effects of obesity and overweight. These benefits include a decreased likelihood of being underweight, reduced blood pressure, and a reduced risk of stroke, colon cancer, and osteoporosis. Dairy products provide a valuable combination of nutrients, such as proteins, fatty acids, vitamins, and minerals, that are essential for the maintenance of blood health, the support of the nervous and immune systems, the improvement of vision, the support of muscle and nerve function, the maintenance of skin health, the maintenance of energy levels, and the overall growth and repair of the body. Furthermore, dairy products can function as carriers for bioactive compounds and may provide a variety of health benefits, such as improved immune function, reduced risk of cardiovascular disease, reduced bone mass loss, and protection against free radical damage, when consumed in an appropriate quantity. Incorporating fruits and vegetables in a variety of forms—including fresh, desiccated, powdered, juiced, pureed, pulped, or extracted—into dairy products such as yogurt, ice cream, and cheese also presents an opportunity to improve their health benefits.

23.1 Introduction
Various products can also be produced by emulsions that contain fat globules. For instance, cream is produced when milk contains concentrated fat. This cream can be further processed to produce butter, ghee, and butteroil. “Milk fat, ghee, butter oil, anhydrous milk fat, and anhydrous butter oil are fatty products that are exclusively derived from milk or products obtained from milk, or both, through processes that result in the almost complete removal of water and milk solids, not fat.” The method of manufacturing (FSSAI standards) has notably influenced the flavour and physical structure of ghee.

23.2 Types of Fat Rich Dairy Products
23.2.1 Cream or Malayi
“Cream is a yellowish component of milk that naturally rises to the surface when milk is allowed to stand. It is rich in fat globules.” Cream is mechanically separated in the dairy industry. The size of the fat globules is diminished as a result of homogenisation of cream, which renders the product less suitable for whipping.
Cream can be defined as
1. That portion of milk, which is rich in milk fat
2. That portion of milk into which has been gathered and which contains large portion of milk fat
3. When milk fat is concentrated into a fraction of the original milk that portion is called cream.

27.1 Introduction
Processed organic food typically consists of solely organic ingredients. If there are any non-organic components, a specified proportion of the food’s plant and animal ingredients must be organic, and any non-organic ingredients must meet specific agricultural standards. Organic foods should not contain artificial additives and are usually processed using fewer synthetic methods and materials, avoiding practices like chemical ripening, food irradiation, and genetic modification. While synthetic pesticides are prohibited, non-synthetic pesticides are permitted. Milk from cows—or any other animal—serves as a useful environmental indicator for measuring pollutants and pesticides because substances consumed by the animal end up in the milk it produces. If contaminants are present in the grass, they will ultimately be found in the milk.

27.2 Beyond these four main factors have led to the increasing interest by farmers and consumers in organic dairy farming
1. Consumer concerns about food safety and animal welfare
2. Overproduction of food (perceived as low in quality)
3. The environmental effects of intensive farming

Asia and the Pacific collectively feed over 4.5 billion people and account for one?third of global agricultural trade. Yet the region’s agri?food supply chains face mounting pressure from climate change, geopolitical disruptions, infrastructure gaps, and volatile markets. This report analyzes fifteen focus countries to distill common challenges, showcase good practices, and highlight investment and policy opportunities that can transform regional agri?food systems into resilient, inclusive, and sustainable engines of growth.

2.1 Purpose and Scope This report provides a comparative assessment of agri?food supply chains across fifteen Asia?Pacific countries, examining how each nation navigates production, aggregation, processing, logistics, and market access. The study integrates quantitative data (GDP, export volumes, logistics indices) with qualitative insights from multilateral agencies, peer?reviewed studies, and practitioner case studies. 2.2 Defining Agri?Food Supply Chains An agri?food supply chain encompasses the full spectrum of activities
