Abstract

The invention belongs to the technical field of polysaccharose extraction and particularly relates to a method for extracting polysaccharose from sesame seed meal through a biological enzyme method. The method for extracting the polysaccharose from the sesame seed meal through the biological enzyme method comprises the following steps: (1), pretreatment of raw materials; (2), enzymolysis; (3), non water-soluble polysaccharose conversion; (4), centrifugal separation; (5), soluble polysaccharose extraction. Due to the adoption of zymosis, conditions are mild, enzymolysis to fat and cellulose in the sesame seed meal is performed by adopting different enzymes, polysaccharose therein is extracted, the utilization ratio of the sesame seed meal is improved, and after the adoption of the method provided by the invention, the polysaccharose is not only high in yield, but also high in purity.

Description

technical field [0001] The invention belongs to the technical field of polysaccharide extraction, and in particular relates to a method for extracting polysaccharide from sesame meal by biological enzyme method. Background technique [0002] Sesame is one of the four major oil-bearing crops in my country. my country is the world's first sesame country. Sesame meal is a by-product of oil extraction from sesame seeds. It is a high-nutrition plant protein resource. It is mainly used as feed or fertilizer at present. Very good development and utilization. [0003] "China Food Additives" disclosed the article "Research on the Extraction of Sesame Meal Protein", which uses sesame meal as raw material to extract protein; The extraction process of sesamin in the meal has been further studied to fully tap the value of the sesame meal, thereby further increasing the added value of sesame; there are few literatures on the extraction of polysaccharides from the sesame meal. [0004] I...
