There are hundreds of millions of microorganisms in the mouth, lactic acid bacteria drinks There are 100 million bacteria per milliliter of sample. Even infant milk powder with higher standards is not "bacteria-free". As long as among the 5 samples of milk powder sampled, the total number of bacteria in no sample exceeds 10,000/g, and there are only 2 at most.

How to stay overnight safely with watermelon?

So if you want to keep watermelon safe overnight, you must do the following:
1. Separate raw and cooked melons, wash and cut the melons, wrap them in plastic wrap and put them in the refrigerator in time. When cutting watermelon, be sure to clean the chopping board, knives and rind beforehand.
2. Plastic wrap can isolate the watermelon from other foods in the refrigerator to avoid secondary contamination; putting it in the refrigerator can reduce the activity of bacteria and make them grow slower.
It is worth noting that the nutrition of ice watermelon will be reduced. The lycopene and β-carotene in watermelon at room temperature are 40% and 139% higher than those in iced watermelon.
If you want the watermelon to be cooler, you can put it in the refrigerator to cool it. The temperature should be adjusted to 5°C to 6°C. The best time should not exceed two hours. This will relieve the heat without hurting the spleen and stomach.
