Abstract

The invention discloses a method for extracting laminarin from kelp. The method comprises steps as follows: raw material processing, ultra-high pressure processing, ultrasonic processing, decoloration, protein removal and drying, and a finished product is obtained. According to the method, two extraction modes are combined, on one hand, the extraction time is shortened, on the other hand, the product yield is increased, and compared with a conventional trichloroacetic acid precipitation method, a savage method and the like, the color and luster of laminarin are good.

Description

technical field [0001] The invention relates to a method for preparing polysaccharides, in particular to a method for extracting laminaria polysaccharides from kelp. Background technique [0002] Kelp (Laminaria Japonica Aresch) is a large seaweed belonging to the genus Laminaria of the family Laminaria. Kelp is rich in a variety of functional components and has extremely high edible and medicinal value. Its medicinal value has been recorded in traditional medical books such as "Compendium of Materia Medica", "Shen Nong's Materia Medica" and "Food Materia Medica". Studies have shown that the various biological functions of kelp are mostly related to the physiologically active polysaccharides in kelp, such as immune regulation, anti-tumor, anti-coagulation, lowering lipids, lowering blood sugar, and anti-oxidation. [0003] There are also many scholars who have studied and discussed the preparation methods of laminarin polysaccharides. The traditional methods are mainly acid...
