Perhaps many people think that storage in plastic bags is one of the reasons for deterioration of watermelon. If wrapped in a fresh-keeping film, the shelf life of watermelon will be prolonged. In fact, no matter what kind of watermelon is stored and what form of preservation is used, bacteria will grow on the surface of the cut watermelon. Refrigeration can only inhibit the proliferation of bacteria, but can not freeze the bacteria. Watermelon is rich in glucose, fructose and other substances, which provide nutrients for bacterial reproduction, and these bacteria easily lead to diarrhea, food poisoning and so on.
