Is there a difference between pasteurization and ultra-pasteurization? I noticed that some organic milk sold in stores in labeled ultra-pasteurized.

    It is common for organic milk brands to be ultra-pasteurized, meaning that it is heated to at least 280 degrees F for two seconds or longer. Some companies do this to give milk a longer shelf life-as long as sixty days! However, this can take away the natural taste of the milk and cuts down of nutrients, reducing Vitamins A, C, D, and E. One organic milk company that doesn’t do ultra-pasteurization is Straus, which heats milk to 170 degrees and cools it down to 40 degrees right after. This milk has a shelf life of 16 days instead.
