Estimation of an equivalent "12D" process by the normal distribution method

Abstract

A new statistical approach is suggested, and illustrated, for estimating an equivalent "12D" irradiation process based upon survival curves or partial spoilage data which appear to follow a normal instead of an exponential distribution. Application of this method to partial spoilage data derived from five individual inoculated ham packs gave more reasonable results than those computed by the conventional method based upon exponential death kinetics.
