manufacturers Dried fruits are fruits whose peels are in a dry state when they are ripe. fruit. After the fruit is fully mature, due to the different moisture content and the difference between dried fruits and fleshy fruits, fruits with dry skin after maturity are called dried fruits. Dried fruits also have split fruits and closed fruits. Most of them are rich in protein, vitamins, etc. There are many common dried fruits in our lives, such as chestnuts, hazelnuts, cashews, walnuts, melon seeds, pine nuts, lotus seeds, ginkgo, almonds, jujubes, peanuts, etc.
Dried fruits must be placed in a dry environment to avoid moisture. Generally, a well-ventilated place is better. It's better to put it in a sunny room. Wrap it in a plastic bag before storing it.
Products that are well stored and packaged are less affected by the storage environment, but dried fruit products that are not carefully packaged or have damaged packaging are easily susceptible to deterioration under adverse conditions. Good storage conditions should be ensured and storage period management should be strengthened to ensure the safety of the products. Storage. The lower the storage temperature, the longer the shelf life of the product. The storage temperature is preferably in degrees Celsius and generally should not exceed degrees Celsius. High temperatures will accelerate the deterioration of dried fruit products and lead to the occurrence of undesirable phenomena such as insect damage and mold growth. The drier the air, the better. The relative humidity of the air in the storage environment should be below 10%. High humidity is conducive to the growth of mold in products. It will also increase the moisture content of dried fruit products, reduce the sulfur dioxide content in dried fruit products that have been treated with sulfur, and increase the activity of enzymes. Destruction of ascorbic acid, etc. Light will cause the product to change color and lose its fragrance, so the product should be packaged or stored away from light. The presence of air will accelerate the discoloration of the product and the loss of vitamins. It will also cause fat oxidation and worsen the flavor. Therefore, dried fruit products are often packaged in evacuation or nitrogen filling. Antioxidants can also be used to protect pigments during product storage. Antioxidants include erythorbic acid. wait.
The commonly used storage methods in the past were salt, moisture-proof plastic wrap, moisture-proof liquor, insect-proof peppercorns, insect-proof sugar cubes, Coke bottles, mineral water bottles, sand, quick lime, tea storage methods
Since the storage conditions of nuts are getting higher and higher, they are now stored in cold storage It is becoming more and more common that dry fruit cold storage generally belongs to the higher temperature category in cold storage. There are still some differences between dry fruit cold storage and ordinary cold storage. Dried fruit cold storage has stricter requirements for temperature and humidity. You can see a lot of dried fruit food packaging. It is marked on the bag that it should be stored in a cool and dry place. This is why the humidity in the cold storage should not be too high and the temperature should not be too high or too low. When building the cold storage, a cold storage control system such as a temperature and humidity controller can be installed.
It is better to store dried fruits in cold storage on shelves. This is conducive to the moisture-proofing of the cold storage and can also play a role in extending the storage period of food. In addition, the selection of refrigeration accessories such as air conditioners and air conditioners for the refrigeration unit of the dried fruit cold storage is also very particular. Determine according to the size of the dried fruit cold storage. Anhui Jinxue Refrigeration Equipment Co., Ltd.
