Tips for overnight meal handling:
Put it in the refrigerator as soon as possible after eating, so as to shorten the storage time at room temperature and slow down the growth and reproduction of bacteria in vegetables. It must be heated and burned back before the next meal, because some pathogenic bacteria can make people sick, although they will not cause food deterioration.
If food is heated, most microorganisms in food can be killed. Microwave oven can destroy the internal structure of microorganisms in a short time, and the sterilization effect is better than that of traditional "burning". Of course, at the same time of heating sterilization, vitamin C in vegetable foods will be destroyed and some nutrients will be lost.
