Which foods are better to choose: frozen or canned? Let's compare the methods for different parameters.
Harvest
For preservation and freezing, freshly harvested crops are taken, for example, vegetables harvested on natural soil, not in greenhouses, literally 2 hours after harvesting, are used in the production of canned cucumbers and tomatoes from the TM Skatert-Samobranka.
Safety
When preserved by pasteurization, all harmful microorganisms die, but vinegar, salt, and sugar are used for preservation, which are not desirable in large quantities.
When freezing, the temperature of -10 C is sufficient so that the microorganisms do not multiply, but freezing does not destroy the microorganisms, but only stops their reproduction, therefore repeated freezing is highly undesirable.
Useful and nutritious substances.
During pasteurization, useful and nutritious substances, as well as vitamins and trace elements, are preserved, vitamin C and B are slightly reduced, but at the same time, if you take tomatoes in their own juice, then during preservation they increase the concentration of lycopene, a powerful antioxidant that protects cells. In particular, during conservation, natural fermentation of products occurs, which has a beneficial effect on health and the digestive tract.
When frozen, all the nutrients of a fresh product are preserved, which can fully replace the use of freshly harvested ones.
Taste
Marinades and pickling give vegetables a new bright taste, they become a separate dish.
During freezing, the taste remains as close as possible to the fresh product. However, ice may form, which will destroy the texture and may lose its appearance and taste during defrosting. Cucumbers and tomatoes are not recommended to be frozen, as after defrosting the texture becomes too watery and practically unusable.
Expiration date
Canned food is stored for at least 2 years, no freezer is required for storage.
In the case of freezing, the shelf life is much shorter - up to 15 months. Frozen foods should be consumed immediately and not refrozen.
What conclusion can be drawn? Both methods preserve freshly harvested products for a long time, preserve nutrients and vitamins, and when choosing, you should be guided by your own preferences and health and diet.
