Question

Explain how pasteurisation is done​

Answer 1

Answer:

Pasteurisation makes sure milk is safe to drink (by killing any bacteria) and also helps to prolong its shelf life. The process of pasteurisation involves heating milk to 71.7°C for at least 15 seconds (and no more than 25 seconds). Once the milk has been heated, it is then cooled very quickly to less than 3°C.
