High quality storage life

While frozen food is stored at 0°F/– 18°C slow changes are taking place in colour, texture and flavour. ‘High quality storage life’ is judged as the time taken for these changes to be noticeable in comparison with the equivalent fresh food. Opinions vary as to the length of this storage life, in relation to a person’s senses of taste and smell. Foods with a high fat content or with highly volatile ingredients have a shorter life than vegetables, for instance, and should therefore only be stored for a relatively short time.
