A Digital Computer Program for the Statistical Analysis of Heat Resistance Data Applied to <i>Bacillus stearothermophilus</i> Spores

Abstract

Summary. A digital computer program is described which fits log‐linear regression lines to survival curves and thermal destruction time lines and performs appropriate statistical tests. The use of the program is illustrated with heat resistance data from 4 strains of B. stearothermophilus spores at 8 time–temperature relationships. D, F, z D and Q 10 values were calculated by the computer program. The heat resistance of the strains was in the order of B &lt;C &lt;A &lt;D.
