Scientific storage conditions of cherries: The suitable temperature for storage is 0 to 1Â°C, relative humidity is 90 to 85%, and the gas index is: oxygen 3 to 5%, carbon dioxide 20 to 25%. 3. Selection of storage cherries: The cherries used for storage should be selected from the storable varieties, and the fruits should be large in size, bright in color, and soluble in solids.

Scientific storage methods for cherries: Plastic bags for small packages: Self-regulating atmosphere-based storage methods: Select cherries without scratches, packed in 0.06 to 0.08 mm thick polyethylene film bags, each containing 2 to 5 kg. The bag is tightly closed and placed in a small carton and stored at a temperature of 0 to 1Â°C. If it can be washed with 100ï½ž500mg/kg Benzalide solution before bagging, drain the bag and store it, the storage effect is better. Generally it can be stored for one and a half months. During the storage period, it is advisable to check the carbon dioxide concentration in the bag. If the carbon dioxide content is 10 to 25%, it will be favorable for storage, and if it exceeds 30%, the odor will be generated.
