The difference between zero-degree preservation and cold storage

Refrigerator is a fresh-keeping appliance that every family will use. It plays a very important role. People can put fresh vegetables in the refrigerator when they buy food. After buying meat food, they can keep it in the refrigerator because they haven't eaten it for various reasons or have leftovers that are not cooked. Now that technology is developed, there is a more advanced zero-degree preservation technology. What's the difference between zero-degree preservation and refrigeration?

First, zero-degree preservation.

The zero-degree fresh-keeping technology was first initiated by Siemens, which mainly broke through the usual low-temperature fresh-keeping thinking. Keeping food in a specific vacuum state can well inhibit the proliferation of aerobic cells in the air, reduce the oxidation of food and achieve the best fresh-keeping effect.

Second, refrigeration.

Generally speaking, the temperature of the refrigerator is between 0 and 8 degrees. This storage method is also called high-temperature refrigeration, which mainly reduces the speed of biochemical reaction in food, inhibits the speed of microbial change and effectively prolongs the freshness of food.

Zero-degree preservation is to keep food fresh in the form of vacuum, while refrigeration is to keep food fresh in the range of 0-8 degrees. These two preservation methods are different, and the effect of preserving food is also different.
