Thermal Processing:

Since many of the processes utilized to preserve foodproducts depend on the addition of thermal energy, it is important to understandits underlying principles. The design ofa thermal process to achieve food

preservation involves two principles:

(a) the use of elevated temperaturesto increase the rate of reduction in themicrobial population present in the rawfood material (Microbial populationmay refer to the number of vegetativecells existing in food product or to thenumber of microbial spores in a given mass of food

(b) the transfer ofthermal energy into the food products as required for achieving the desired

elevated temperatures.
