Abstract
A method for inhibiting microbial contamination, particularly applicable to processes for preparing food materials under nominally aseptic conditions, is carried out by cycling the temperature of a desired portion of the process which is a source of contamination between upper and lower limits which fall between 0.degree. and 60.degree. C. and which are at least 5.degree. C. apart at a frequency of about 0.2 to 5 cycles per hour to create a varying thermal environment at the source of contamination which slows microbial growth.
