Problems solved by technology

[0003] The total flavonoid content in the leaves of Polygonum multiflorum is very rich, and the content of vitamin B2, vitamin C and carotene is relatively high. Among them, the content of vitamin B2 and vitamin C is 2-40 times that of ordinary vegetables, and the content of carotene is 2-300 times that of ordinary vegetables. In addition, it is also rich in Ca, Fe, Cu, K, Mn, Zn, P, and various amino acids necessary for the human body. It is a precious resource integrating nutrition, health care and medicinal functions. However, due to the It has a certain bitterness, and its water content is relatively large, and its surface has a certain oiliness, making it difficult to remove the bitterness, and the shelf life is short, so it is difficult to be widely used, resulting in a large amount of Polygonum multiflorum leaves being wasted
