Pasteurisation is the process which intended to reduce spoilage organisms and eliminate vegetative bacteria but not bacterial spores.

pasteurization involved heating a foodstuff to high temperature and then cooling it rapidly. This helps in destroying harmful microbes without changing the composition flavour or nutritive value of the foodstuff .This process is named after the French chemist Louis Pasture who discovered it in the 19th Century. Commercially available milk is first heated to a high temperature for about half a minute and then cooled rapidly it is then stored at temperature lower than 10 degree Celsius .
