When cooking vegetables, let the surface of the vegetables be exposed to high temperature for a while, and the inside is definitely not ripe. The reason for this is that most bacteria on the surface of vegetables can be killed, because there are not many harmful bacteria inside vegetables, and fruits and vegetables should be thoroughly cleaned. Soak them in special detergent or flour water 10 minute, and then rinse them with running water to improve the cleanliness of fruits and vegetables.
