超高温消毒法, (Ultra-high-temperature processing、ultra-heat treatment，简称UHT，或ultra-pasteurization)是一种通过在极短时间内加温为食物灭菌的方法（用135~150°C加热2~3秒）。这个温度才能够杀死残留在牛奶中的孢子。最常用这种方式来消毒的有牛奶，不过这种过程同样运用于果汁、奶油、豆浆、酸奶、葡萄酒、汤、蜂蜜以及浓汤。这种消毒法在1960年代被发明，并于1970年代逐渐可行起来。

Ultra-high temperature processing (UHT), ultra-heat treatment, or ultra-pasteurization sterilizes food by heating it above 135 °C (275 °F) – the temperature required to kill spores in milk – for 1 to 2 seconds. UHT is most commonly used in milk production, but the process is also used for fruit juices, cream, soy milk, yogurt, wine, soups, honey, and stews. UHT milk was first developed in the 1960s and became generally available for consumption in the 1970s.
