Precautions for using crisper boxes

　　Refrigerator crispers are of great benefit to food preservation. They can ensure that people keep food as isolated as possible to prevent cross-contamination.

　　Experts analyzed that on the one hand, the low temperature of refrigerators cannot completely kill microorganisms and prevent enzyme catalysis and food oxidation. Many psychrophilic microorganisms can grow in low-temperature environments below 0 degrees Celsius. As the storage time increases, food will still spoil. On the other hand, if food is stored in the refrigerator and raw and cooked food are not separated, cross-contamination will occur. Raw fish, raw meat, cold drinks, fruits, leftovers, leftovers, etc. are stored in the refrigerator at the same time without tight packaging. Once one kind of food goes bad, it will quickly contaminate other foods and induce chain deterioration and taste change. Using a fresh-keeping box can better solve the above problems.

　　In addition, experts remind you that there are several precautions when using refrigerator crispers:

　　1. Take out the crisper box from the freezer. Do not open it immediately. Let it sit at room temperature for 1-2 minutes before opening it.

　　2. When used in a microwave oven, if the food contains a lot of oil and sugar, the temperature will rise rapidly, which will cause the crisper to deform. Therefore, it is best to use a special box for microwave ovens to heat the above foods.

　　3. The bubbles in carbonated drinks (soda, cola, etc.) will cause the sealing ability of the crisper to be lost. Bubbly food, fermented food, hot food, etc. will reduce the sealing performance of the crisper. Please try to avoid storing such foods in the crisper.

　　4. Different foods have different storage times. Don’t rely solely on the sealing ability of the crisper. It’s better to eat them as soon as possible.
