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.
How do I store the milk?
Pour the cooled milk into sterilized containers right away. Put the containers in the fridge to cool the milk to 4°C (40°F) or colder.
How long can I store milk?
You can store pasteurized milk in the fridge for 2 weeks. It’s a good idea to label the milk with the date it was pasteurized.
How to Pasteurize Milk
FAQ
Can you pasteurize things at home?
Raw milk can also be pasteurized in a microwave oven. Heat to 165°F using a thermometer or temperature probe. Stir the milk once or twice during the heating period to equalize the temperature throughout. Cool as directed.
Is pasteurization just boiling?
Pasteurization in the United States involves heating milk up to about 160°F for the purpose of killing bacteria that could make you sick. The boiling point of milk is about 212°F, so it is never actually brought to a boil during the pasteurization process.
How is the pasteurization process done?
Batch pasteurization involves heating every particle of milk in a large tank or vat to a minimum of 145° F for a minimum of 30 minutes. Examples of continuous flow pasteurization are: High-Temperature, Short-Time (HSTS) pasteurization: requires that the milk be held at a minimum of 161°F for 15 seconds.
How long does it take to pasteurize?
Heat the milk to 63°C (150°F) for at least 30 minutes or 72°C (162°F) for at least 15 seconds. If the temperature falls lower than the one you’re using, you have to start timing again.
