FOOD TECHNOLOGY

Detailed explanation-1: -The refrigerator temperatures are those between 0 and 7°C, and are suitable for the storage of a large number of perishable and semiperishable foods. Temperatures below 5°C will prevent the growth of most food poisoning bacteria.

Detailed explanation-2: -Freezing prevents the growth of most foodborne microorganisms and refrigeration temperatures slow down the growth of microorganisms. Refrigeration below 5 °C effectively retards the growth of many foodborne pathogens. The cooling rate is important in controlling the growth of microorganisms.

Detailed explanation-3: -At temperatures below their optimum for growth microorganisms will become increasingly unable to sequester substrates from their environment because of lowered affinity, exacerbating the anyway near-starvation conditions in many natural environments.
