How to Buy Frozen Food Correctly?
1. Understand the storage period and storage temperature How long can frozen food be stored? Based on the expiration date printed on the product packaging, frozen meat can be stored for 3 months at a temperature of -18ºC. This means that as long as the food is continuously stored at a temperature of -18ºC after leaving the factory, there should be no quality issues within 3 months. However, if the storage temperature cannot be maintained at -18ºC or below after leaving the factory, the food may deteriorate in quality within 3 months. Under low temperatures, microorganisms cannot grow, but the flavor and taste can gradually deteriorate, fats can oxidize, and vitamins can degrade. Therefore, the expiration date printed on the packaging for 3 months does not guarantee the quality of the food within that timeframe. In addition, in reality, when customers buy frozen food and bring it home, the ambient temperature can affect the food to some extent, even if it is not completely thawed....
