Food preservation methods generally include refrigerator preservation, cling film, fresh-keeping bags, traditional connection type crisper, and new concept crisper.
Refrigerator preservation
Most Chinese people's "food storage" method is a refrigerator to get everything, thinking that such food will not rot, deterioration, absolutely insurance. In fact, the refrigerator is definitely not a safe! The nutritional value of food is not only its congenital growth factors, but also the acquired environment. The control range of the preservation temperature of the refrigerator is large, which affects the adaptability of different foods to the temperature, and it cannot guarantee that all the foods are in the best preservation state. For example, Apple's most suitable storage temperature is 0-1 degrees Celsius, and cucumber is 7-8 degrees Celsius. If the two kinds of foods are stored in the refrigerator at the same time, they will "disregard each other." What's even more frightening is that low temperature does not kill bacteria. Microorganisms in the refrigerator will become active once the temperature conditions are right. Untreated leftovers will be contaminated by pathogenic bacteria and cause food poisoning.

Plastic wrap, fresh bags
In order to overcome the refrigerator freezing defects, people have begun to extensively use plastic wrap and fresh-keeping bags to preserve food. After the plastic wrap and the fresh-keeping bag are packaged, the moisture content of the food evaporates, and the freshness preservation time is several times longer than that stored in the refrigerator without treatment, and the problem of odor between foods can be solved to some extent. However, the plastic wrap and the fresh-keeping bag have poor durability and tightness, and the food with a strong taste pollutes the environment in the refrigerator. Packed food piles are messy in the refrigerator. Fresh effect: ★ ★
Traditional connection type crisper
Traditionally-connected crispers have now become popular on the market. The preservation function of the crisper is even more advanced than the cling film and storage bag, and the odor is basically solved. However, this type of crisper also has a problem in design: if the lid and the box body are closely attached to each other, though the sealing performance is greatly enhanced, the switch is difficult and is not suitable for the use of the elderly and children; but if it is easy to switch, this will greatly Reduce the sealing performance of the crisper.

New concept crisper
In order to solve the problem of the conventional connection type crisper, the latest type of crisper has systematically studied the problems existing in the traditional crisper, and has launched a new product with a double locking system. It uses a four-sided combination of the box surface is closed, the surrounding pressure is even, can play a 100% sealing effect. Experiments have shown that the freshness of the crisper can be more than three times that of similar products. Furthermore, the Lock & Lock Lock brand, which is based on the concept of “saving time, space and moneyâ€, currently has more than 150 types of crisper types with different specifications, which can solve various food collections.
