How is milk pasteurized? In most milk processing plants, chilled raw milk is heated by passing it between heated stainless steel plates until it reaches 161° F. It’s then held at that temperature for at least 15 seconds before it’s quickly cooled back to its original temperature of 39° F.
Can you pasteurize milk at home?

How do you pasteurize?
The most common method of pasteurization in the United States today is High Temperature Short Time (HTST) pasteurization, which uses metal plates and hot water to raise milk temperatures to at least 161° F for not less than 15 seconds, followed by rapid cooling.
