उत्तर
Milk is pasteurised in order to kill any kind of harmful microorganism present in it and to increase its shelf life. Pasteurisation is a process in which the milk is heated to a certain temperature for a fixed period of time and then is quickly cooled. For example, it may be heated at 80°C for 15 minutes and then immediately cooled. This helps to kill any kind of microorganism which is present in milk.
