Abstract

This article contains a brief review of some "unconventional" applications of the Arrhenius law. One such example is proposed as a problem concerning the shelf-life of frozen food (Italian pizza) at temperatures ranging from 0 to -18 °C. The effective activation energy (180 kJ/mole) calculated from the information presented by the manufacturer implies that the most probable mechanism of pizza deterioration on storage is enzyme and microbial destruction.
