Dairy, dairy quite contrary

How does your bacteria grow?

With metal grates and heated plates,

And filthy cows all in a row.

 

Ever wonder how your milk gets from the cow to your bowl of cereal? Grist.org just did a great story on dairy. Essentially, milk goes through a 3-step process of pasteurization, homogenization and fortification. Here is a list of must-know terms from today’s milk production.

Pasteurization

Pasteurization is the process of using heat to destroy microorganisms in foods. Do you know the difference between pasteurized, ultra-pasteurized, and raw?  Here are the 4 main ways dairy is pasteurized:

High Temperature Short Time (HTST)
This is the most common method of pasteurization in the U.S. HTST uses metal plates and hot water to raise milk temperatures to at least 161F/72C degrees for a minimum of 15 seconds, followed by rapid cooling.

Ultra Pasteurized (UP)
Milk or milk product is heated to 280F/138 C degrees for two seconds. UP results in a product with longer shelf life, but still requires refrigeration. Most organic milk is ultra pasteurized to extend the shelf life.
