Abstract

The invention discloses a method for extracting laminarin from kelp. The method comprises the steps as follows: raw material treatment, ultrasonic treatment, enzymolysis, decolorization, deproteinization and drying. During raw material treatment, enzymolysis is performed after ultrasonic treatment, the characters of proteoglycan protein can be well kept while raw material gelling and denaturationof proteoglycan protein are caused by long-term high-temperature heating treatment in the prior art, and the method can effectively improve the laminarin extraction efficiency as compared with the prior art.

Description

technical field [0001] The invention relates to the extraction technology of laminarin, in particular to a method for extracting laminarin from kelp. Background technique [0002] Laminarin, in a narrow sense, laminarin refers to laminarin. Because people gradually downplay the difference between kelp and kelp, it is called kelp polysaccharide, also known as kelp polysaccharide. In a broad sense, it refers to the polysaccharide components purified from kelp, including kelp oligosaccharides, fucoidan, and kelp starch. Due to the lack of corresponding decomposing enzymes in the human body, the human body cannot directly absorb laminarin through eating kelp. The concentration of laminarin in kelp is too low, and the purification of laminarin is a technology with high cost and very complicated process. These reasons have led to people not having a comprehensive and correct understanding of laminarin. With the advancement of science, laminarin will be recognized by more peo...
