It's widely known that fruits have a short shelf life at room temperature. Currently, controlled atmosphere cold storage is a trendy new method for storing fruits, and it has also gained popularity among many distributors. Among them, apples, grapes, and kiwis have high economic value when stored in controlled atmosphere cold storage, with a storage period that can last over 60 days.

In normal air, the oxygen content is typically 21%, while carbon dioxide is 0.03%. Fruits undergo metabolism primarily driven by respiration, which accelerates their aging. A controlled atmosphere cold storage is designed to provide an optimal storage environment for fruits, keeping them in a state of dormancy. When storing apples, plums, grapes, kiwis, garlic, potatoes, chestnuts, and other fruits in a controlled atmosphere cold storage, it allows for long-term preservation.

The characteristics of a controlled atmosphere cold storage for fruit: It maintains the fruit's shape, color, and fragrance effectively; the hardness of the fruit after storage is higher than that of general refrigeration; compared to general refrigeration, the fruit stored in a controlled atmosphere storage has a longer shelf life, extending the sales time after inventory. The controlled atmosphere storage reduces the rate of spoilage and natural loss in fruit; it is suitable for long-distance export and large-scale fruit storage; it provides off-season supply, avoiding the peak season of fruit market, and increases the sales price.
