Abstract
ABSTRACTA series of computer oriented procedures was developed to facilitate the rapid handling of heat penetration data while providing estimates of the process time required to achieve a specified lethality at a single point within the product for a particular product, container size, fill and processing conditions. Accepted thermobacteriological equations were employed with variation in the heating rate used to establish confidence limits on processes. This statistical approach was considered more pragmatic than the traditional use of the slowest or mean single value of the heating rate in sterilization calculations while the amount of heat penetration data necessary for process determination was minimized. Varying computer program versions permit the application of these process determination procedures to high or low acid products that are convection or conduction heating providing they exhibit single or broken straight‐line heating curves.
