Embodiment Construction

[0014] Below in conjunction with embodiment the present invention is described in further detail.

[0015] Remove the diseased roots and fibrous roots of hijiki, and rinse them with clean water. Dried in a blast-type constant temperature oven at 55°C to a water content of 10%, pulverized with a pulverizer, and then passed through an 80-mesh sieve to obtain a dry powder;

[0016] Take 50 grams of the above-mentioned dry powder and add 1500 ml of water to extract at room temperature for 2 hours, treat it with a 900W ultrasonic ice bath for 11 minutes, and centrifuge the above-mentioned extract at 4500 rpm for 10 minutes to obtain a supernatant and a precipitate; put the precipitate at 80 ° C Extract with water at high temperature for 1 hour, then centrifuge as above to obtain supernatant 2 and precipitate; extract the precipitate with 2% sodium carbonate alkali for 1 hour, and centrifuge in the same way to obtain supernatant 3 and precipitate.

[0017] Combine the supernatants ...

Abstract

The invention relates to an extraction method of sargassum fusiform active polysaccharide, which uses four-step extraction method as combined ultrasonic extraction, water extraction, alkali extraction, hot water extraction and ultrasonic technique, thereby improving sargassum fusiform polysaccharide extraction rate and avoiding damage on sargassum fusiform activity in polysaccharide extraction. Besides adding the character of polysaccharide on extract, the prepared sargassum fusiform active polysaccharide has high oxidation resistance, which is suitable for cosmetic technical field. In addition, the prepared sargassum fusiform polysaccharide uses active carbon adsorption and AB-8 macroporous adsorption resin to combine decolor and de-fishy, thereby resolving the key techniques as decolor and de-fishy of sea phaeophyceae polysaccharide as sargassum fusiform or the like, to improve polysaccharide purity, appearance quality and confirm the high oxidation resistance of de-fishy and decolor polysaccharide.

Description

technical field [0001] The invention relates to the field of biochemistry, in particular to an extraction process of hijiki active polysaccharides. Background technique [0002] Sargassum fusiforme (Harv1) Setchell is a plant of the family Sargassum, also known as sea barley, staghorn tip, etc. It is mainly distributed from the Liaodong Peninsula in the north to the Leizhou Peninsula in the south, and it is distributed in the coastal areas of Zhejiang. A large number of data studies have shown that the active ingredient Sargassum polysaccharides (S1 fusiform e polysaccharides, SFPS) extracted from seaweed, in addition to being widely used in the food and health industries, has good anti-cancer and high blood pressure effects, and is also used as a raw material for cosmetics. It also has good skin care effects, can relieve skin thirst, restore moisture balance, and achieve moisturizing, strong and firm skin effects through biological activation. Hijiki polysaccharides have ...
