Cottonseed oligosaccharide production method

Abstract

A cottonseed oligosaccharide powder, its raffinose content ≥ 30%, stachyose content ≥ 1%, crude protein content ≤ 20%, water content ≤ 5%, can be widely used in food, feed and other industries directly as functional The use of additives; the production method uses three-level concentration gradient methanol to extract the wet-containing meal, respectively removes phenols and sugars, removes most of the gossypol and some pigments in the first level, evaporates and recovers methanol, and discards the residual liquid , the second and third stages extract cottonseed oligosaccharides and remove residual gossypol, evaporate and recover methanol, and separate the residual liquid after recovering methanol, and remove fat-soluble substances and insoluble solid substances containing a small amount of gossypol It is separated from the water liquid, and the water liquid is dried and crushed to produce cottonseed oligosaccharide powder products. The invention has simple process and easy operation, can effectively increase the yield of cottonseed oligosaccharides, is suitable for large-scale industrial production, enables comprehensive utilization of cottonseed, and the product has the advantages of high content of active ingredients, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of cottonseed, in particular to a production method of cottonseed oligosaccharide powder. Background technique [0002] In the prior art CN001345206 "a cottonseed treatment method", a comprehensive utilization method of cottonseed is provided, and the pretreated cottonseed is treated with 6 # Solvent oil leaches oil once, extracts gossypol from the soluble wet meal after oil extraction with methanol, evaporates the methanol liquid after extracting gossypol, uses separation method to remove fat-soluble substances and water-insoluble solid impurities, and extracts the water liquid Crude oligosaccharides are obtained after drying. This method can recover cottonseed oligosaccharides, but the yield of cottonseed oligosaccharides needs to be further improved, and the effects of refining and decolorization also need to be continuously improved and perfected.
