Thermal Process Calculations for Different z and jcValues Using a Hand‐Held Calculator

摘要

ABSTRACTEquations facilitating the calculation of F, or process time used in the design and evaluation of thermal processes for low‐acid foods packaged in hermetically sealed containers for j, values of 0.4–2.3 and a z value of 10–26°F are presented. The relationships are based on the data presented by Hicks (1958) and Hayakawa (1970). The equations, although complex, can be efficiently used to calculate sterilization values and processing times using presently available programmable calculators. The equations were developed and tested so the maximum error in a calculated result will not be more t
