FOOD TECHNOLOGY

Detailed explanation-1: -Freezing delays spoilage and keeps foods safe by preventing microorganisms from growing and by slowing down the enzyme activity that causes food to spoil. As the water in the food freezes into ice crystals, it becomes unavailable to those microorganisms that need it for growth.

Detailed explanation-2: -Chilling a food product reduces the risk of bacterial growth. Rapidly chilling (also known as flash freezing or cryogenic freezing) a product mitigates this risk even further. Cryogenic freezing also maintains the natural quality of food.

Detailed explanation-3: -Freezing keeps food safe by slowing the movement of molecules, causing microbes to enter a dormant stage. Freezing preserves food for extended periods because it prevents the growth of microorganisms that cause both food spoilage and foodborne illness.

Detailed explanation-4: -Foods are stored at low temperatures to prevent the growth of microorganisms, activity of enzymes, and purely chemical reactions. Freezing prevents the growth of most foodborne microorganisms and refrigeration temperatures slow down the growth of microorganisms.

Detailed explanation-5: -In the case of refrigeration, the idea is to slow bacterial action to a crawl so that it takes food much longer (perhaps a week or two, rather than half a day) to spoil. In the case of freezing, the idea is to stop bacterial action altogether. Frozen bacteria are completely inactive.
