(2) High Temperature and Short Time Method

In this method, milk is heated to 161°F (Fahrenheit) for 15 seconds and then immediately cooled to 40 Celsius. The same method is mostly used to pasteurize milk. Due to this process milk can stay good or fresh for a longer time.

(3) Ultra High-Temperature Method

In this method, milk is heated to 275°F (Fahrenheit) for one to two seconds. It increases his life by nine months.
