Bananas and plantains constitute the fourth most important global food commodity (after rice, wheat and maize). They are cultivated in over 120 countries in the tropical and subtropical regions of the world in an area of  approximately 100 million hectares, where they constitute a major staple food crop for millions of people, as well as providing a valued source of income through local and international trade.
 
Banana is one of the oldest fruit crops of India, finding its reference even in epics like Ramayana. India is  believed to be one of centres of  origin, besides southeast Asian countries like Burma, Thailand, Malaysia and Indonesia. It is a crop having multifarious uses as every part of the plant is utilized and hence aptly  called as ‘Kalpatharu’ the plant of virtues. It is important internationally from the point of view of  trade as well as livelihood security.

Zeatin: Zeatin is a cytokinin C₁₀H₁₃N₅O first isolated from the endosperm of Indian corn.

Zeaxanthin: Zeaxanthin is an isomer of lutein occurring in fruits and vegetables (spinach and corn) (Plate 260, 261 and 262).

Yabby: It is one of the burrowing Australian crayfishes (Cherax destructor) that are used for food.

Yakitori: A bite-size marinated pieces of beef, seafood, or chicken on skewers is called yakitori.

Yam: It is edible starchy tuberous root of plants (genus Dioscorea of the family Dioscoreaceae) used as a staple food in tropical areas.

Yautia: It is one of the aroid plants (Xanthosoma sagittifolium) chiefly of tropical America with starchy edible shaggy brown tubers that are cooked and eaten like yams or potatoes.

Yearling mutton: Meat obtained from 12-20 month aged sheep. It is also called Earling mutton.

Yeast: Unicellular plant body, very minute in size containing cell wall, cytoplasm with one or more vacuoles and a single nucleus, cause alcoholic fermentation (Plate 258). Yeast usually has little or no mycelium, and reproduces by budding. It results in production of yellowish surface froth or sediment that occurs in saccharine liquids (fruit juices) in which it promotes alcoholic fermentation, consists largely of cells of a fungus (as the saccharomyces, Saccharomyces cerevisiae), and is used in the making of alcoholic liquors and as a leaven in baking.

Xanthan gum: It is a polysaccharide that is produced by fermentation of carbohydrates by a gramnegative bacterium (Xanthomonas campestris) and is a thickening and suspending agent used in pharmaceuticals and prepared foods. It is also called xanthan. Xanthan is a stabilizer produced by Xanthomonascompestris(Plate 257). Xanthan is not hydrolysed or degraded by humans.

Wafer: A thin crisp cake, candy, cracker or chips is known as wafer.

Waffle: A crisp cake of batter baked in a waffle iron is called waffle

Warner-Bartzler Shear: It is one of the oldest but commonly used devices used to measure the tenderness of meat. It is used to test the quality in the cooked meat

Vacreation: The pasteurization of the milk or cream under reduced pressure by direct steam is called vacreation.

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.

U value: U value is a measure of the heat transmission through a building part (wall or window) or through a given thickness of a material (insulation). U values with lower numbers indicate better insulating properties.

UHT milk: This milk is homogenized, heated to atleast 135^oC for about 2-3 second, cooled rapidly and then packed in sterilized containers aseptically. The milk in packs can be stored for several months without refrigeration. The nutrient loss is negligible. Used for making yogurt commercially as it does not need to be boiled again.

UHT pasteurization: The milk is heated to ~150^oC for a fraction of seconds practically no holding period. It is also called ultra pasteurization.

UHT sterilization: It is method in which food is sterilized, cooled and then aseptically placed in previously sterilized containers which are subsequently sealed in an aseptic environment.

Ultimate analysis: It is used for determination of a particular element or a compound in a food material.

Ultra heat treated milk: It is designation of the milk sold for liquid consumption after subjection to ultra high temperature to sterilize the milk by killing bacteria and other microbes including spores.

Table cream: It is also called coffee cream, single cream or homogenized cream. It is used in coffee and tests about 20% butter fat.

Table oil expeller: It is a type of the machine that is used for extraction of the oil from the oil seeds (Plate 230).

Saccharification: The process of breaking a complex carbohydrate (starch or cellulose) into its monosaccharide components is called saccharification.

Saccharimeter: A device (polarimeter) used for measuring the amount of sugar in a solution is called saccharimeter. It is also known as saccharometer. It is a hydrometer with a special scale.

Saccharin: A crystalline compound C₇H₅NO₃S that is unrelated to the carbohydrates, is several hundred times sweeter than sucrose, and is used as a calorie free sweetener.

Packaging is defined as an enclosure of products, items or package in a wrapped pouch, bags, box, cup, bottle or any container form to perform one or more of the functions as containment, protection and preservation, communication and utility or performance. Technically, packaging is a system or method by which a product from the manufacturing point to the consumer level reaches in a safe and sound condition at an affordable cost. The primary purpose of the packaging is to protect the food product, to keep it in good condition and to preserve the flavour until it reaches the consumer. It is therefore, very essential that a suitable form of the packaging is chosen for a finished product. Packaging is an art, which determines the buying decision of a consumer. or Wrapping / placement of objects in paper / other packaging materials, keeping in box, etc is known as packaging which has two main functions, to assemble the produce / objects in convenient units for handling and to protect them during transporting, marketing and storage which results in extended shelf life of the produce. "Packaging" play a very important role not only in ensuring safety of the product during transportation, storage and distribution and in conveying information about the pack contents to the consumers, but also ensuring desired sensory characteristics and microbiological soundless till consumed.

Objective Methods: Objective Methods are used for evaluation of food quality. These are based on recognized standard scientific tests to any sample of the product without regard to its previous history.

Introduction of Food Industry

India is one of the major food producers in the world. The food sector contributes to about 28% of India's GDP. India stands at 1st position in the world for production of cereals, milk, livestock, banana and Mango, 2nd in producing fruits and vegetables and ranks amongst top 5 in producing rice, wheat, groundnut, tea, coffee, tobacco, spices, sugar and oilseeds. India's share in global production of fruits is 10% and vegetables are 13.7%. The current consumption of fruits and vegetables is approx Rs.2 lakh crores at current prices with an estimated growth rate of 11% per annum. The growth rate is higher than cereals and milk and comparable to meet consumption

Status of Food Processing Industry

The food processing industry in India is still in a sorry state. The rural population comprising 70% including small cities, consume less than 10% of the processed foods and vegetables, whereas 60% of the processed food is consumed in four major metropolitan cities and 30% in the state capitals and big cities. Another fact is that 40% of the processed food and vegetables produced in the country in terms of value are bought by institutional buyers like Hotels, Restaurants and Defense etc. The highest growth in domestic market has been in fruit drinks, tomato ketch up and Jams.

There is another fact that India is the largest milk producer in the world, however, organized industry accounts for less than 15% of the milk produce in India. It is estimated that there may be a total production of 1100 million tons of production of food products mainly food grains, oilseeds, sugarcane and fruits/vegetables during 2011-12 and leaving marketable surplus of 870 million tons.

Purpose of Law

The Food Laws or Regulations are made in order to protect people consuming these foods from undue risks, which may arise from processing, transport, retailing and consumption of food products which may undergo contamination, spoilage, inclusion of harmful chemicals/microbes or at harmful levels. Besides safety, consumers are also protected by these laws with respect to quality, quantity and substance that the food products are supposed to represent. Finally, laws also aim to protect the consumers from Nutrition and Health considerations with special consideration being given to vulnerable group such as infants, pregnant women etc.

Food additives are chemical substances added to foods to improve flavour, texture, colour, appearance and consistency or as preservatives during manufacturing or processing. Herbs, spices, hops, salt, yeast, water, air and protein hydrolysates are excluded from this definition.

In many countries, the use of food additives is regulated, and food additives must be declared on food labels by using their chemical names or numbers. the use of any new additive in a particular food, they ensure that:
