Fresh jujube dried after dehydration, known as red dates. The jujube used for storage should be dry and moderate, without damage, no pests, and ruddy in color and neat in size. Jujube has a higher sugar content and has greater hygroscopicity and oxidative properties, so the storage temperature and humidity should be reduced as much as possible during storage. Low temperature is the main method to reduce the loss of vitamin C in jujube fruit. Drying is not conducive to the growth and reproduction of microorganisms.
During jujube storage, in addition to excessive humidity caused by fermentation deterioration and mildew decay, rice moths, wheat moths, stolen and other pests, will also be harmful to red dates. Therefore, we should also pay attention to rat prevention. So, what is the method of storing dates?
Northern Storage
For mass storage, sacks are used for storage. When palletising, there must be a gap between the bag and the bag, between the cymbal and the cymbal, to facilitate ventilation. The walls are somewhat moist and do not get too close to the walls.
Southern Storage
The high temperature and humidity in the south and mildew season should be stored in cold storage. Dates are packed in sacks and stored in warehouses at 5°C. Before going out of the cold storage, it is necessary to move to a slightly higher temperature and gradually move out of the library. For water vapor condensation on the jujube fruit into water droplets, do not immediately re-bagging, but to air dry, and other condensation beads disappear, and then change bags for shipment.
A small amount of red dates can be stored in rice husk ash. Spread rice husk on the ground about 1 cm thick, spread a layer of red dates, sprinkle rice husk ash covered with red dates, and then spread a layer of red dates. This storage method can prevent moisture, bactericidal, dried dates, and has a good effect.
