The causes of fruit and vegetable ageing and spoilage after fruit and vegetable picking are roughly due to the ethylene gas produced by the respiration of fruits and vegetables, various biologically active enzymes present in fruit and vegetable components, water evaporation, and microbial proliferation. One of the most important factors is that the various biological enzymes that cause ripening and aging and the ethylene gas produced by the respiration in fruits and vegetables can cause yellowing, softening, spoilage, and deterioration of fruits and vegetables. At present, the preservation of fresh fruits and vegetables is mainly based on the cold storage method, which has a large one-time investment, high cost, complicated operation, and is not conducive to long-distance transportation. This article describes the film preservation technology of fruits and vegetables is based on the characteristics of physiological changes in fruits and vegetables after picking, scientific selection of the role of human consumption and antioxidant anti-oxidants, fungicides, antibacterial agents, filming agent composite fruit and vegetable coating Preservation solution, as long as the liquid immersed, sprayed or applied to the surface of fruits and vegetables to form a layer of semi-permeable semi-permeable breathable fresh film, without refrigeration, ordinary fruits and vegetables at room temperature for up to 4 months, difficult to keep fresh The shelf life of varieties (such as litchi, strawberries, etc.) is also more than one month, while the cost per kilogram of preservation is only about 3 cents. First, the process: fresh fruits and vegetables → cleaning → surface sterilization detoxification → cleaning → coating → storage Second, the coating solution preparation: (1) inositol hexaphosphate composite solution 0.20%; (2) CM film forming agent 1%; (3) sodium benzoate salt 0.20%; (4) sucrose ester 0.10%; (5) water, balance; (6) pH 4. According to the above formula, several ingredients are dissolved in clean and non-polluting water, and the pH is adjusted to the specified range to be the coating fresh-keeping solution. Third, the process points: (1) Select fresh, pest-free fruits and vegetables preservation. (2) The surface of fruits and vegetables is sterilized and detoxified. Oxidized bactericide is selected to remove residual pesticides and various germs on the surface. (3) The surface coating of fruits and vegetables can be immersed, coated or sprayed in any one way. After the coating is dried, it can be air-dried or dried by Fengfeng. (4) This Law can be applied to the storage and preservation of various agricultural products such as fruits and vegetables, tender corn and chestnut. (5) The fruits and vegetables after film coating should be stored in a cool house or cellar. The house or cellar where the fruits and vegetables are stored should be sterilized before use.
