Description
Technical Field

Background
Sargassum fusiforme is a perennial warm-temperate seaweed belonging to the genus Sargassum of the family Sargassaceae, the family Laminariaceae, and the family Laminariaceae. Mainly distributed in the Liaodong peninsula in North and the peninsula in south to Rezhou, which are the most distributed in the Zhejiang coastal areas. A large number of data researches show that the sargassum fusiforme polysaccharide extracted from the seaweed has good anticancer and hypertension effects besides being widely applied to food and health care industries, and also has good skin care effects by being added as a cosmetic raw material, can relieve skin thirst, recover water balance, and achieve the effects of moisturizing, strengthening and firming skin through biological activation. The sargassum fusiforme polysaccharide has important application value in the industries of health care products, medicines and cosmetics. It is mainly used in antioxidant facial mask and cream skin care product, and has effects of preventing skin relaxation and wrinkle, improving skin pigmentation caused by ultraviolet, and removing senile plaque and other pigmented spots.
In recent years, methods for extracting and purifying polysaccharides have been rapidly developed, and new methods including HPLC methods, enzymatic methods, membrane separation methods, and the like have been increasingly developed. However, for various reasons, these methods have not been widely used. At present, a neutral hot water leaching method or an acid leaching method is mostly adopted. Most of various nutrient components mainly containing sargassum fusiforme polysaccharide are water-soluble substances, so that the sargassum fusiforme polysaccharide can be extracted by a hot water extraction method; the extraction method is simple and feasible, convenient to operate and low in equipment requirement, but the production time is long, the polysaccharide yield is not high, and the waste is serious. Acid leaching tends to destroy specific structures in the polysaccharide that are associated with immune activity, and both methods have their disadvantages.
