Summer is the peak season for refrigerators. However, many people still need to improve the method of refrigerating food. Many people put the food directly in the refrigerator, or simply wrap it in plastic bags or plastic wrap, and then put it in the refrigerator. Such refrigeration of food is not conducive to keeping the food fresh, it is also easy to cause nutrient loss, and even unintentionally contaminate the food. In contrast, the use of fresh-keeping boxes for refrigerated food is safer and healthier.
Food preservation requires three conditions of temperature, humidity and gas. Putting it directly in only guarantees low temperature. Humidity and gas will be destroyed invisibly; ordinary plastic bags cannot be sealed, so humidity and gas cannot be kept naturally, and some plastics The bag is not dedicated to food and may contain toxic ingredients; qualified plastic wrap, which basically contains no harmful substances, can isolate gas circulation and water loss to a certain extent, but its sealing performance is not good, and the effect of preservation is not very ideal. . The fuse box not only ensures that different foods can be placed in isolation to prevent cross-contamination, but also makes reasonable use of storage space without causing nutrient loss. At the same time, the food is placed in a crisper to prevent food from "smelling", thereby ensuring the originality of the food. Authentic.

Take out the fresh-keeping box from the freezer, do not open it immediately, leave it at room temperature for three or four minutes before opening it, because the best freezing principle for food is "quick freezing and slow thawing", this way, the food can be guaranteed The integrity of the cell structure ensures that the nutrients in the food are not lost. If the food is just taken out of the refrigerator and the packaging box is opened, the bacteria in the surrounding air can easily contaminate the food through condensed water vapor. After leaving it for a period of time, the chance of such contamination will be greatly reduced.
