1. The freezing room of display cases
can be used to make ice cubes and frozen food.
2. Store the purchased frozen food in the freezer as soon as possible.
3. Before freezing the food, the food should be wrapped first, so as to better maintain the moisture and flavor of the food, and then put the food in the freezing room.
4. It is never advisable to put tofu and fresh vegetables in the freezing chamber, otherwise they will be frozen.
5. To defrost frozen foods such as fresh fish and meat, put them in the refrigerator a few hours before cooking. If you want to thaw food quickly, put these foods in plastic bags and brew them with tap water.
6. Generally speaking, food should not be frozen after it has been completely thawed. If the food is still frozen or there are ice crystals, it is not a problem to re-freeze. However, the quality and taste of such foods may be reduced, and because they cannot be stored for a long time, they should be eaten as soon as possible.
How long can I keep frozen food? According to the instructions on the package, it can be stored at -18°C for 3 months. This has two meanings: if it has been stored at -18°C after leaving the factory, it can be eaten with confidence within 3 months without obvious quality problems; if it has not been stored at -18°C after leaving the factory, there is no guarantee 3 A decline in quality occurred within a month.
If you look at the shelf life instructions on various food packages, you will find that most of them have temperature conditions. is 48 hours at 0~4℃ and is definitely not equal to 48 hours at 20℃. Some bread packages even indicate 3-4 days in the second and third quarters and 5-7 days in the first and fourth quarters. why? This is because all chemical and enzymatic reaction rates are affected by temperature. Under freezing conditions, microorganisms basically do not multiply, but the taste and flavor are still slowly changing, fat will be slowly oxidized, and vitamins will be slowly decomposed.
