what is the temperature of pasteurization?give the significance of this temperature.?

Answer 1

Foods are heat-processed to kill pathogenic bacteria. Foods can also be pasteurized using gamma irradiation. Such treatments do not make the foods radioactive. The pasteurization process is based on the following time and temperature relationship.


High-Temperature-Short-Time Treatment (HTST) - Using higher heat for less time to kill pathogenic bacteria. For example, milk is pasteurized at 161° F (72° C) for 15 seconds.

Low-Temperature-Long-Time Treatment (LTLT) - Using lower heat for a longer time to kill pathogenic bacteria. For example, milk is pasteurized at 145° F (63° C) for 30 minutes.
