Answer 2

Milk is preserved by the method of pasteurization. Pasteurization is done to kill bacteria from milk, thus preserving it for a longer time. In this process, foods such as milk and fruit juice are treated with mild heat . Due to this, pathogens are killed, and also the enzymes responsible for spoiling or curdling milk become denatured.
