Ultra-high-temperature processingWikipedia
Ultra-high temperature processing (UHT) ultra-heat treatment or ultra-pasteurization is a food processing technology that almost sterilizes liquid food by heating it above 135 °C (275 °F)the temperature required to kill many bacterial endosporesfor 2 to 5 seconds. UHT is most commonly used in milk production but the process is also used for fruit juices cream soy milk yogurt
