In contrast, dietary N kinetics differed with UHT milk and were characterized by lower retention (68% vs. 76%) than MF milk. The HTST pasteurization process is a continuous process accomplished by heating the product to 71.5°C and passing through a holding tube at a rate that ensures the required holding time. The increased temperature results in a greater reduction in bacteria and heat-resistant enzymes, for an extended shelf-life. Allows for creation of aseptic-shelf stable items. The price listed in USD is the nominal exchange when the group buy was priced. Ultra-pasteurized milk lasts three times longer than HTST processed milk because the higher temperature not only kills the usual suspects like E.
