Regular quick-frozen food is generally free of preservatives, which is still related to its preservation technology. Using low-temperature quick-freezing freezing technology to preserve freshness can already inhibit the reproduction of microorganisms, and there is no need to add additional preservatives. It can be said that it is no different from the food we usually eat, only safer.


In contrast, the safety of non-frozen foods is actually more difficult to judge. All kinds of fresh food bought in supermarkets may be more likely to breed microorganisms because they are exposed to room temperature for too long.
