What is the cold storage temperature of fruits?

Generally speaking, the fresh-keeping temperature of fruit cold storage is-1 ~ 15℃.

Fresh-keeping storage can reduce the incidence of pathogenic bacteria and the decay rate of fruits, and also slow down the respiratory and metabolic processes of fruits, thus achieving the purpose of preventing rot and prolonging storage period. Different fruits are refrigerated at different temperatures, such as mango 10~ 12*C, pineapple 7 c, and some fruits will be frostbitten if the refrigeration temperature is too low, causing skin damage.

Some suggestions on fruit cold storage and preservation

1. precooling of fruits

Pre-cooling can inhibit the vigorous respiration and transpiration of fruits, reduce the loss of water and nutrients, and make fruits better adapt to the cold storage temperature environment.

2. The reservoir temperature and relative humidity remain stable.

During the storage of fruits in cold storage, the storage temperature should be kept stable, and the temperature fluctuation should not exceed 65438 0℃. If the temperature is too high, the fruit will ripen, while if the temperature is too low, the fruit will freeze. In addition to temperature, humidity is also very important for fruit preservation. If the humidity is too low, the fruit will shrink. Therefore, it is necessary to configure humidifiers and other equipment in the warehouse to keep the humidity stable.

3. Avoid mixing different kinds of fruits.

The storage temperature of different fruits is quite different, and mixed storage is easy to cause freezing injury or after-ripening. Some fruits, such as bananas, apples, etc., belong to respiratory climacteric fruits. When they mature, they will release ethylene and accelerate fruit ripening. If conditions permit, it is recommended to use it in a special warehouse.
