Chutian Gold Newsletter Gold News (Reporter Yu Ning correspondent Li Juanjuan) In Wuhan, it is not a joke to eat apples that are picked on trees in Shandong. The reporter learned from the large-scale direct harvest festival of the 10th anniversary of Carrefour Agriculture Super Matchmaking yesterday that the fresh-keeping methods of fruits and vegetables began to move toward “no treatmentâ€â€”physical technology that does not require preservation of chemicals. This kind of technology is called air conditioning, and the storage carrier is still a traditional warehouse form. The industry calls it “Air Conditioning Libraryâ€. According to Huang Zhengzhong, fresh director of Carrefour, air-conditioned storage, also known as air-conditioned storage, is the most advanced fresh-keeping method for fruits and vegetables. The principle is to “sleep†fruit or vegetables that have just been picked. The controlled atmosphere store can control the metabolic process of fruits and vegetables by controlling the conditions such as temperature, humidity, carbon dioxide, oxygen concentration and ethylene concentration. After the fruits and vegetables are released from the library, they will “revive†from the “sleep†state. The air-conditioning storehouse extends the shelf-life of fruits and vegetables by 21 to 28 days, which is 3 to 4 times that of ordinary cold storage. The reporter saw the "fruit picking, product direct supply, no preservatives," the word brand of fruit on the shelves, there are few varieties of apples, grapefruit, oranges and other varieties, Apple's price is 4.8 yuan per catty, not more expensive than the market price . According to the promoters, Apple is from Shandong Province. It uses at least 70% organic fertilizer throughout the plantation, promotes manual weeding, has no production regulators, and has no chemical preservation after picking.
