Abstract

Thermal sterilization indicator process, apparatus and test indicator product which enable indication of microbial sterility achieved during a thermal sterilizer cycle by measuring visible light absorption due to chemical change in an encapsulated liquid indicator material, including measurements taken when a thermal sterilizer cycle is completed without a time delay requirement for spore growth, and in which the liquid indicator material includes a growth nutrient and microbes, so as to enable verification of achieved microbial sterility by measurement of the liquid indication subsequent to an incubation period following completion of the thermal sterilizer cycle.
