Six strokes to improve refrigerator fresh-keeping effect

The refrigerator itself already has some preservation technology, but for some ordinary users, it is still hoped that there are more practical methods and tips to help improve the preservation effect. Here we will introduce some tips to help you keep fresh.

1. Food placed in the refrigerator should be fresh and clean as much as possible. Because of the good quality food, the microbial base is small, which can reduce the total number of microorganisms after breeding, and it is not easy to contaminate other foods stored in the refrigerator.

2. The food placed in the refrigerator should have a certain packaging. Including wrap film covering, its role is to prevent food freeze-drying, odor, mutual pollution, and reduce the number of defrosting.

3. The fish and meat to be frozen should be packaged according to the size of the household. Prevent large pieces of food from being thawed many times and affect its nutritional value and umami taste, while also saving electricity.

4. Place the potatoes in an old carton and put three or four immature apples in the carton. Because the apple will emit some ethylene gas during the ripening, and the ethylene gas will keep the potatoes fresh for a long time.

5. It is best to heat the leftover food first. After the food is cooled, put it in the refrigerator and refrigerate it. If it is refrigerated for more than 24 hours, it should be cooked and then eaten.

6. Cut the pork into two or three inches long pieces, covered with honey on the meat surface, and then hung in the indoor ventilation area with twine. The pork treated in this way can not only be stored for a long time, but also tastes more delicious when cooked. (Chen Chen)
