Process for preparing red alga oligose

Abstract

The present invention discloses process of preparing red algae oligose with acid treated solid cationic exchange resin as medium. The preparation process has the advantages of the repeated use of acid treated solid cationic exchange resin, low cost, no acid liquid exhaust, no corrosion to the production apparatus and less technological steps. The product has carrgeenin oligose with obvious effect of antagonizing pneumonia virus and herpes virus, relatively high effect of inhibiting tumor cell, effect of inhibiting the growth of Bacillus subtilis, etc; and agaragar oligose with high antioxidant and liver protecting effect.

Description

technical field

[0001] The invention relates to a method for preparing oligosaccharides, in particular to a method for preparing red algae oligosaccharides. Background technique

[0002] Red algae polysaccharides extracted from red algae mainly include agar gum and carrageenan. Red algal polysaccharides have a long history of application in food and medicine, and red algal oligosaccharides are low-molecular-weight compounds obtained after polysaccharide degradation. In recent years, many physiological activities of this type of oligosaccharides and their derivatives have been gradually recognized. Oligosaccharides have been reported in anti-oxidation, anti-inflammation, hypoglycemic and anti-tumor aspects; and carrageenan oligosaccharides are a kind of natural polyanionic sulfate oligosaccharides, so they have anti-tumor, antibacterial, anticoagulant and other aspects. Its unique activity, in addition, as an antiviral active substance, carrageenan oligosaccharide has a good...
