Detailed explanation-1: -Ultra-high temperature processing (UHT), ultra-heat treatment, or ultra-pasteurization is a food processing technology that sterilizes liquid food by heating it above 135 °C (275 °F) – the temperature required to kill bacterial endospores – for 2 to 5 seconds.
Detailed explanation-2: -Learn about this topic in these articles: Ultra-high-temperature (UHT) pasteurization involves heating milk or cream to 138–150 °C (280–302 °F) for one or two seconds. Packaged in sterile, hermetically sealed containers, UHT milk may be stored without refrigeration for months.
Detailed explanation-3: -Ultra-High Temperature (UHT) Pasteurization At UHT Pasteurization, the product (particularly milk) is heated to 130-150 °C for 0.5-1.0 second. This is considered by some to be a sterilization process, rather than pasteurization, and results in a significantly longer shelf life.
