Question

What is food preservation?

Answer 1

Food preservation:

• The process of treating and handling food to stop or slow down food spoilage and the deterioration of quality, thus allowing food for longer storage, is called food preservation.
• It works on the principle of delaying the self- decomposition of food and killing microorganisms.
• It helps to maintain the same taste and flavour and to prevent the growth of microorganisms.
• Nowadays, modern techniques, such as canning, pasteurization, freezing, and adding chemicals are used to preserve food.
• Chemical preservatives such as benzoic acid and sodium benzoate are used in preserving fruits and vegetables.
