Freezing is one of the most popular methods of preserving food. This technique does not require any specialized skills, substantial financial investment, or a significant amount of time. Freezing allows for a substantial reduction in food waste, the preservation of the taste of seasonal products, and can also help in saving money. These are just a few of the advantages of this preservation method. It can be assumed that in today's times, when the zero waste philosophy is gaining increasing importance, freezing can play a very significant role.
What are the principles of freezing?
According to the Polish language dictionary, freezing involves subjecting food to low temperatures to maximize its shelf life and preserve its nutritional value. In domestic conditions, the maximum temperature in freezers is around -18°C, while it is even lower in professional manufacturing plants. The faster a product is frozen, the better its structure, taste, and appearance are preserved. However, it is crucial to remember that already thawed food should not be refrozen, as this increases the risk of bacterial growth and severe food poisoning.
