Can you boil milk to keep it from spoiling?
Boiling kills the microorganisms which spoil milk – along with any others. However, it does change its taste, which is one reason why boiling milk is not used more often as a means to preserve it. Pasteurization works by heating milk without boiling it, which kills some bacteria but doesn’t change its taste no much.
