What is the difference between sterilization and pasteurization?

When is dry heat necessary for sterilization compared to moist heat?

What are the most effective wavelengths of radiation?

What is the difference between ionizing and nonionizing radiation?

Solution

Pasteurization is a heat treatment method of food preservation that kills the microorganisms present in the food. It involves a low heat treatment procedure so the nutrient value of food is not lost.

Sterlisation is another form of thermal processing of food which uses high temperature to increase the shelf life of food products. The main objective of this method is to destroy the spores of bacteria which cannot be destroyed with any other method.

Sterlisation involves heating of food at 110° to 120 whereas pasteurization involves heating at 70 to 80°C.
