Question

how does pasteurisation prevent the spoilage of food? which category of the food is preserved by this method?

Answer 1

Pasteurization can be defined as the technique to reduce the number of microorganisms present in a food product by heating the food product at a high temperature to a fixed time period and then immediately cooling and storing it. The microorganism in the food are killed by treatment at high temperature as high temperature denatures the enzymes present in microorganisms and kill the cells.

Pasteurization is most commonly used for liquid food products like milk and beer.
