Watermelon is the most common fruit in summer, but how can it be preserved in summer?
Select excellent quality skinny watermelon with good skin and medium head, wipe the skin with a dry cloth first, then soak it in salt water with a concentration of 15-20% for about half an hour, remove it and put it in a ventilated place until the moisture of the watermelon epidermis naturally evaporates. After that, seal the watermelon with a clean food bag and store it in a cool, ventilated place. Always turn watermelons over, so that watermelon can be preserved for 4-6 months, even longer, still fresh, sweet and delicious
Eat watermelon to eat fresh. The cut watermelon is best eaten in a short time. Because watermelon pods are a good medium for bacteria. According to a doctor's test, Shigella was able to reproduce 50,000 times after 12 hours on the melon. When buying melons, it is not easy to be greedy, but according to the population and food intake; the cut melon should be eaten as soon as possible and must not be stored for too long. Usually 2 to 3 days. The watermelon is best to buy now and eat. If you buy it warmer, you may wish to increase the temperature of the refrigerator and then refrigerate it. The best flavor is within two hours of refrigerating time.
When you cut watermelon at home, you must first wash the knife clean, and immediately cut open and put a clean plastic wrap into the refrigerator. And try to buy cut watermelon as little as possible. If you must buy it, you can't trust it. You can cut off the watermelon on the surface before eating.
Storage of home watermelons The whole watermelon is wrapped in cling film, because the watermelon skin also oxidizes with the air and degrades the watermelon and puts it in the refrigerator. Cut short-term storage of watermelon and cover it with plastic wrap. Store it in the refrigerator. If you do not have a refrigerator, you can store it with a cling film for about a day.
Some media carried out experiments. In the experiment, the workers sampled the surface of the cut surface of watermelon, 4 cm below the surface, and 8 cm below the surface. Each sample was sampled at 1 gram, and was chopped and placed in the medium. Twelve hours later, dense colonies were distributed in the three samples. The experimenter said that the number of bacteria is difficult to count and needs to be calculated in hundreds of millions of units, among which, the surface of the bacteria is the most. Finally, we came to the conclusion that hundreds of millions of watermelon bacteria were overnight, and we appealed to everyone to throw away the overnight watermelon.
Subsequently, a CCTV program also made related experiments. The results showed that after 4 hours of refrigerating, the number of bacteria in the plastic wrap was 65, which was higher than that of the unsealed watermelon. After waiting for 20 hours, the watermelon content of the unwrapped watermelon film was 80 per gram. In the case of the watermelon with the plastic wrap, the bacterial content was as high as 210 per gram. Experts inferred that the watermelon covered with plastic wrap did indeed promote the growth of bacteria.
Therefore, after the watermelon used plastic wrap, it is still a layer of meat removed, eating.
A lubricant used to reduce the frictional resistance of a pair and to slow its wear. Lubricants can also cool, clean and prevent pollution on friction pairs. Appropriate additives may be added to some lubricants to improve lubrication performance. When choosing lubricant, it is necessary to consider the motion of friction pair, material, surface roughness, working environment and working conditions, as well as the performance of lubricant and other factors. In mechanical equipment, lubricants are mostly delivered to the parts that need lubrication through the lubrication system.
