Does boiling milk extend its life?
Yes, boiling the raw milk does increase its shelf life and make the milk last longer. The boiling process kills many bacteria present in the raw milk, thus prolonging the shelf life of the milk. Thus simply boiled milk lasts for about 2-3 days in the fridge in an air-tight container or bottle at or below 40°F.
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.
