In continuous pasteurization, however, the milk is never stagnant in a container, but is pushed between a hot pipe to heat it up in a method known as High Temperature, Short Time (HTST). At this point, the milk’s temperature can range from 161.6°F for 15 seconds to 280°F for 0.01 seconds. HTST pasteurization preserves the nutrient composition better than low temperature, long time pasteurization (LTLT).

Grade A dairy products must meet the basic requirements of the PMO to be sold to stores and consumers (you!).
