Save leftovers:
1, pay attention to cooling. Everyone should know that hot food can't be refrigerated in the refrigerator, only cold leftovers can be preserved. If the food is not cooled and then put into the refrigerator, the food center is prone to qualitative change, and the hot air brought by the food will cause the condensation of water vapor and promote the growth of mold, which will lead to the overall mildew of the food in the refrigerator.
If you put it in the refrigerator after cooling, it can inhibit bacteria and slow down the spoilage of food, and you can continue to eat it next time.
2. It should be simply stored. Different foods must be stored in different ways. You can't put all the food together, so it's easy for all the food to rot quickly. Because put together, bacteria produced by different foods can easily cross together, which will accelerate food spoilage and make food worse. Can be stored separately with plastic wrap or plastic bags.
3. Save control time. Leftovers can't be eaten as long as they are kept. Generally speaking, they should not be kept overnight. It is best to control it within 6 hours and heat it when eating.
