Vitamin levels in food are reduced during preparation and processing and over time. Only vitamins D and Biotin seem to be unaffected by storage, processing and cooking.

Vitamins B2, E and K are light-sensitive. For that reason foods contain these vitamins should be stored in dark places to minimise a reduction of these vitamins through storage.

Freezing of the food has little effect on vitamin content. Cooking before freezing, however, can reduce the amount of vitamins.
