Importance of Food Preservation: Food production and supply does not always tally with the demand or meets of the people. In some places there is surplus production of a food product, whereas in some other place there is inadequate supply. Even foods are perishable and semi-perishable like juicy fruits, vegetables, mangoes, tomato, papaya and many more, which very quickly gets spoilt. It is therefore important to improve and expand facilities for storage and preservation of food. 

Food preservation helps in : 

• It increases the self-life of foods thus increasing the supply. 

• Making the seasonal food available throughout the year. 

• Adding variety to the diet. 

• Saving time by reducing preparation time and energy, as the food has processed. 

• Stabilising prices of food, as there is less scope of shortage of supply to demand. 

• Decreasing wastage of food by preventing decay or spoilage of food. 

• Improving the nutrition of the population. Preserved foods help people to bring a variety in the diet, thereby decreasing nutritional inadequacies.
