Abstract

The invention provides a processing method of high-purity aloe acetylated polysaccharide, comprising the steps of: peeling and crushing the aloe, filtering to obtain the aloe juice, adding the pectinase in the aloe juice according to the additive amount of 50-70 ml / ton of aloe juice, adding the active carbon in the aloe juice according to 0.1-0.3 of the mass of the aloe juice, then stirring for 20-40 min for enzymolysis and decolorization, and standing until the aloe juice is clear; thereafter, filtering by the microfiltration membrane with filtration aperture of 10 mu m, the filtration membrane with filtration aperture of 0.2 mu m and the ultrafiltration membrane with filtration aperture of 0.001 mu m, concentrating by the reverse osmosis membrane and drying to obtain the aloe powder, the mass content of the aloe acetylated polysaccharide reaches 15%. The invention realizes continuous separation at the normal temperature and enables various functional compositions in the aloe to be fully separated without adding any assistant, thereby the purity of the aloe acetylated polysaccharide is guaranteed and the extraction and separation costs are reduced.

Description

technical field [0001] The invention relates to a processing method of aloe acetylated polysaccharide, which belongs to the technical field of plant processing. Background technique [0002] In recent years, the United States has carried out more in-depth and detailed research on aloe polysaccharides. The research has confirmed that the ingredients in aloe polysaccharides that have anti-viral infection, anti-inflammatory, and bactericidal effects, maintain cell vitality, and improve body immunity are actually a kind of O-acetyl-containing glucomannan, commonly known as aloe acetylated glucomannan, referred to as aloe acetylated polysaccharides. The molecular weight distribution range of aloe acetylated polysaccharides is relatively small, ranging from 60,000 to 100,000. Under normal circumstances, the content of aloe acetylated polysaccharides in fresh leaves of aloe is extremely low, only 0.5‰~1‰, and the content of aloe acetylated polysaccharides in ordinary 200:1 aloe ge...
