Process for deprotein in refinishing polyose

Abstract

The invention relates to a deproteinization method in polysaccharide refine manufacture. Decreasing the temperature of plant or fungus polysaccharide water extract, adding organic acid, adjusting the pH value to 3.5-4.5, mixing equal, reacting for 1-2 hours, taking centrifugal separation, using the supernatant, adjusting the pH value to 7.0, concentrating the liquid , drying, the polysaccharide that has been deproteinized would be gained. The invention has high efficiency, low cost, simple technology, high recurrence rate, etc.

Description

technical field

[0001] The invention belongs to a method for extracting and processing plant active ingredients, in particular to a deproteinization method in polysaccharide refining. Background technique

[0002] At present, in the production and refining of plant and fungal polysaccharides, the commonly used deproteinization methods are protease method and Sevag method. Protease method, due to the specificity of the enzyme, makes the protein removal rate vary due to different raw materials, and its effect is unstable. Sometimes the removal rate of protein is not ideal. And protease, as a biological agent, is expensive, resulting in a higher cost of the product. The Sevag method has a high protein removal rate, but it needs to use a large amount of organic solvents in the removal process, and the process is complicated, which not only brings hidden dangers to product safety, but also has low efficiency.
