Explanation:

Fruits and vegetables are important supplement to the nutritional requirements in the human diet as they provide the

essential minerals, vitamins and fiber required for maintaining health. India is the second largest producer of fruits

and vegetables in world after China. Huge quantity of produce is wasted due to inadequate facilities for

preservation as only 1.5 to 2% of the total produce is processed in the country. Fruit and vegetable preservation is

thus one of the major pillars of food industry. The food preservation and processing industry has now become a

necessity rather than being a luxury.

Food is the prime necessity of life and can be classified in different groups according to their nutritional value and

function in the body.

1. Energy giving food: Any food which provides energy is classified as energy giving food. One gram of

carbohydrate imparts 4 calorie while 1 g of fat provides 9 calorie of energy, e.g., cereals, roots, tubers,

dried fruits, sugar, fat etc.

2. Body building food: Foods which are rich in protein are body building foods, e.g., milk, meat, fish, egg are

rich in protein of high biological value. Secondly pulses, oil, seeds and nuts etc are rich in proteins.

Though, these proteins contain many essential amino acids for synthesis of body tissues yet may not

possess all essential amino acids required for the human body.

3. Protective food: Foods rich in protein, vitamin and minerals are called protective foods, e.g., milk, egg,

green leafy vegetables and fruits. Protective foods are of two types.

• High biological value foods: Foods rich in protein, minerals and vitamin. (e.g., milk) are protective foods of

high biological values.

• Low biological value foods: This group includes foods rich in minerals and vitamins but deficient in

proteins (e.g., fruit and vegetables, green leafy vegetables). Thus, fruit and vegetables are characterized as

the protective foods of low biological value. They are rich source of carbohydrates, dietary fibre, mineral,

vitamins, flavonoids etc.
