Reverse osmosis equipment uses "freshly squeezed" juice concentrates to make a cup

　　In recent years, under the favorable environment of increasing the consumption level of residents and upgrading the consumption structure, the domestic fruit and vegetable juice processing industry has shown an overall good growth trend. According to the data released by the China Commercial Industry Research Institute, China's fruit and vegetable juice output will reach 16.984 million tons in 2020, and it is expected that China's fruit and vegetable juice output will reach 17.53 million tons in 2021.

　　Concentrated fruit and vegetable juice production has good social benefits and certain economic benefits, in order to reduce the processing energy consumption of fruit and vegetable juice, reduce the loss of nutritional components of fruit and vegetable juice, and comprehensively improve the quality of fruit and vegetable juice, the fruit and vegetable juice industry has been seeking to develop new concentration technology.

　　The common method of fruit juice film concentration is reverse osmosis, when the semi-permeable film places the fruit and vegetable juice and the aqueous solution on both sides, the aqueous solution will naturally penetrate to the side of the fruit and vegetable juice solution, so as to achieve osmotic pressure equilibrium. If a pressure greater than the osmotic pressure is applied on the side of the fruit and vegetable juice solution, the flow direction of the solvent will be opposite to the original osmotic direction, and the flow from the fruit and vegetable juice solution to the side of the aqueous solution will begin to flow, so as to achieve the purpose of concentration.

　　Compared with the vacuum evaporation concentration method, the main advantages of The Lightred reverse osmosis equipment are that the fruit and vegetable juice concentration temperature is low, no phase change occurs, the retention rate of aromatic components in fruit and vegetable juice is higher, the flavor of fruit and vegetable juice can be better maintained, the loss of nutrients in fruit and vegetable juice is less, and the heat-sensitive functional components are not easily destroyed.

　　In recent years, China's beverages have maintained a growth rate of about 20%, coupled with China's rich fruit and vegetable resources, the demand for concentrated fruit and vegetable juice exports has gradually shown an upward trend. The application of reverse osmosis equipment technology in the clarification and concentration links, fruit and vegetable juice browning reaction is less, the color is positive, and the nutrition of fruits and vegetables is preserved, which has been further applied in food, beverage and other fields.
