How to preserve the cut watermelon?

1, stored in an air-conditioned room or an ice room. The inedible watermelons are wrapped with plastic wrap and stored in an air-conditioned room or a cool place. After sealing, store the remaining watermelons in water and put them in a basin. Pay attention to wrap the peels together, so that water can't get in, and the water surface of the basin should completely submerge the watermelon. The temperature is very high in summer, and the water temperature will rise soon. So change it in time, at least three times a day.

2. Watermelon can't be kept for too long, because plastic wrap is not everything, and air and water sometimes leak in, which will cause watermelon to breed bacteria and make it uncomfortable to eat. It should also be noted that when eating fresh-keeping watermelon, the exposed position of about 1 on the surface should be cut off, so that it is safe and hygienic to eat.

3. In the process of cutting watermelon, the cut surface will be polluted by air, and the position of the cut surface is likely to have been infected by bacteria. There will still be a small amount of bacteria between the fresh-keeping bag and the sliced watermelon. If it is preserved for too long, the number of bacteria is the same, and it will cause diarrhea after eating it. Therefore, it is best not to keep watermelons fresh for more than 24 hours, and it is best to buy them all at once.
