1, please add some vinegar when heating. Meat and animal foods should be repackaged and heated, preferably with some vinegar. Because these foods are rich in minerals, these minerals will overflow with water when heated. Then add some vinegar when heating, these substances will be synthesized into calcium acetate when they meet acetic acid, which not only improves its nutrition, but also is beneficial to our body's absorption and utilization.

2. When heating, add some seasoning. When heating, it is best to add some seasonings such as wine, onion and ginger to shellfish and seafood, which can not only refresh the mind, but also have a certain bactericidal effect, which can kill Vibrio parahaemolyticus lurking in it and prevent gastrointestinal discomfort, especially ginger, which has the effect of sterilization and detoxification (especially the poison of fish, shrimp and crab) in traditional Chinese medicine.

Please finish it within 4 hours and pack some starchy food. It is best to eat them within 4 hours, because they are easily parasitized by staphylococci. The toxin of this bacterium will not decompose when heated at high temperature, and it cannot solve the problem of deterioration. Therefore, if you don't finish it in a short time, don't eat it again even if it doesn't deteriorate the appearance.
