Freezing is recognized as one of the best methods of preserving food quality.
Low temperatures inhibit the growth of deteriorative and pathogenic micro-
organisms, and retard biochemical and enzymatic reactions that would
otherwise occur in unfrozen food. Although the physico-chemical reactions
slow down at low temperatures, they will nevertheless continue during
frozen storage conditions.
