ultra-heat treated



  • adjective
    (written as ultra heat treated)
    treated by sterilising at temperatures above 135° C, and then put aseptically into containers. Ultra heat treated milk has a much longer shelf-life than normal milk.


  • adjective (A liquid) which has been rapidly heated to 132°C, held at this temperature for 1 to 2 seconds (up to 6 minutes for some products), then rapidly cooled, generally in a stainless steel plate heat exchanger through which the liquid flows as a very thin film. This treatment sterilizes the liquid without too much change in its flavour. However the process does not necessarily destroy enzymes which may induce rancidity after several months.
