How To Pasteurization Milk At Home?

Milk Pasteurization By Using A Stove

 It is the best and simplest method to pasteurize your milk at your home. Pasteurizing milk using a stovetop can be done by constantly stirring the bottom of the bowl to prevent milk from scorching.

However, the process consumes a very long time to reach the optimal temperature. You have to stir in order to distribute the heat from the bottom of the pot to the top layer of the milk.

Uniform heat distribution is essential to achieve superior milk pasteurization. If you make a mistake while stirring the milk, it can cause milk-burning issues and create a mess.

Double Boiler Method

It is much simpler than milk pasteurization using a stove. The double boiler method is very useful as it ensures no risk of scorching.

The process mainly includes two pots, one that fits inside the other. The other pot is filled partially with water, and the inner pot holds fresh raw milk for pasteurization.
