In addition, the nutrients in vegetarian dishes are more likely to be lost. This is because there are usually dozens of nutrients in a food, among which water-soluble vitamins, such as vitamins C and E, are afraid of heat. The nutritional value of vegetables is just reflected in the rich vitamins, so the nutrient loss of reheated vegetarian dishes is serious.
There are also some nutrients in food that are not too afraid of heat, such as minerals such as calcium and iron. People usually ingest these nutrients through meat dishes such as fish, so the loss of nutrients after heating will not be serious.

Main points of leftovers storage
1, leftovers need to be thoroughly cooled before they can be put into the refrigerator. This is because the hot food suddenly enters the low temperature environment, and the food center is prone to qualitative change. The hot air brought by the food will cause the condensation of water vapor, promote the growth of mold, and lead to the moldy food in the whole refrigerator.
2, meat dishes are easy to breed bacteria for 2 hours.
Harmful bacteria in the air will attach to some high-protein and high-fat leftovers within 2 hours. Under the action of bacteria, protein and fat will produce harmful substances, such as hydrogen sulfide, amines and phenols. It is harmful to human body. Therefore, leftovers should be put in the refrigerator within two hours after cooking and put in shallow containers to facilitate cooling.
Do not leave the food for 3.6 hours.
Leftovers should be stored without eating. The leftovers in the morning should be eaten at noon, and the leftovers at noon should be eaten at night. It is best to eat it in 5 to 6 hours. If food is stored for too long, the bacteria in food will release chemical toxins, and there is nothing you can do to heat these toxins.
