What's the difference between a controlled atmosphere storage and a cold storage?

Modified atmosphere storage (CA) is based on cold storage, which increases the adjustment of gas composition, controls the temperature, humidity, carbon dioxide, oxygen concentration and ethylene concentration in the storage environment, inhibits the respiration of fruits and vegetables, delays their metabolic process, better maintains the freshness and commercialization of fruits and vegetables, and prolongs the storage period and fresh-keeping period of fruits and vegetables.

Modified atmosphere storage: 1. Controlled atmosphere storage adopts PLC program automation, which has strong safety and reliability and high production efficiency.

2. Under the same fresh-keeping quality and temperature conditions, the fresh-keeping time of modified atmosphere storage is 3-5 times longer than that of cold storage, and it can even reach dozens of times for some foods, which is incomparable to general cold storage;

3. Using CO2 gas to participate in controlled atmosphere storage can not only effectively inhibit the production and function of ripening components such as C2H4, but also have the functions of sterilization, bacteriostasis and elimination of pesticide toxic and side effects.
