FOOD TECHNOLOGY

Detailed explanation-1: -Freezing has been successfully employed for the long-term preservation of many foods, providing a significantly extended shelf life. The process involves lowering the product temperature generally to-18 °C or below (Fennema et al., 1973).

Detailed explanation-2: -What is freezing food? Food freezing is a food preservation process based on exposing food to temperatures below its freezing point, a point at which the state of matter changes and the properties of the product are altered, turning it into ice and solidifying all the water or moisture contained in the food.

Detailed explanation-3: -Freezing is an effective way to make perishable items last longer.

Detailed explanation-4: -Perishable foods like fish, meat and poultry should be quickly processed and packed using an appropriate technique. Retorting is a method of preserving food by heating it in hermetically sealed containers like cans, glass jars, semi-rigid thermoformed containers and retortable pouches.
