Abstract
A method for extracting pentosan from wheat by-products, which includes the steps: pretreating the wheat by-products by adding warm water at the temperature of 20-45 DEG C according to the liquid-solid ratio of 1:5-10, stirring and scrubbing for 10-30 minutes, filtering impurities with bi-layer gauze, utilizing papain for enzymolysis for 1-2h, eliminating the papain at 90 DEG C while starch pasting is performed, and performing enzymolysis for high temperature resistant alpha-amylase; drying after filtering, and alkalifying for alkaline hydrolysis to obtain deproteinized and destarched wheat bran; and filtering the wheat bran with nylon cloth to obtain pentosan liquid.
Description
Technical field
ThisInvention relates to a kind of working method of polysaccharide, especially a kind of method of from the wheat sub product, extracting piperylene.
Background technology
Wheat bran is the main sub product of wheat flour milling processing, and its ratio accounts for 20% of wheat flour milling amount of finish.Testa Tritici mainly is made up of the cortical tissue of wheat and a certain amount of endosperm and wheat germ, except that a large amount of fibre compositions, also contains nutritive ingredients such as rich in protein, fat, glucide, minerals and vitamins; Therefore, wheat bran is regarded as food fibre resource preferably.Food fibre is non-starch based polysaccharide, can be divided into water-soluble dietary fibre and water insoluble dietary fiber two big classes according to deliquescent difference.Water insoluble dietary fiber is meant one type of that part of non-starch based structural polysaccharide that is not digested and be insoluble to hot water by digestive enzyme in the food fibre; It is mainly the moity of cell walls, comprises Mierocrystalline cellulose, semicellulose, xylogen, chitosan and vegetable wax etc.Though then being meant in the food fibre, water-soluble dietary fibre do not digested by the body digestive enzyme; But dissolve in hot water; And by the isolating one type of non-starch polysaccharide of the ethanol precipitating of certain volume; It mainly is meant water-soluble storage material and secretory product in the vegetable cell, also comprises part microbial polysaccharide and synthetic polysaccharide in addition, and its composition mainly is some gelatin substances.
Piperylene is also claimed araboxylan, and 60 % ~ the 70%th of outer thin-walled of the gluten cell of most of cereal and endosperm layer extracellular thin-walled is made up of piperylene.According to deliquescent difference, piperylene can be divided into two types of water-soluble piperylene and water-insoluble piperylenes.It has physico-chemical properties such as HMW, HV, oxidation gelling; Processing quality for wheat and flour products thereof has material impact, and simultaneously it also has physiologically active piperylenes such as significant reducing blood-fat, fat-reducing, immunomodulatory and other polysaccharide such as common formation plant cell wall framework such as beta-glucan, Mierocrystalline cellulose, pectin and xylogen and keeps the integrity of structure.The especially existence of FLA of phenolic acid in the piperylene can make the possibility that is connected to become between the materials such as itself and other polysaccharide and albumen, and it is connected with other material through covalent linkage or non covalent bond and forms multi-component cell walls network structure.
Summary of the invention
The present invention provides a kind of method of from the wheat sub product, extracting piperylene.
One of the object of the invention is realized through following technical scheme:
(1) wheat sub product pre-treatment: with 60 mesh sieve impurity screenings; Add the warm water of 20-45 ℃ of temperature according to liquid-solid ratio 1:5 ~ 10 ratios, carried out centrifugal 20 min of 3000 r/min agitator treating 10-30 minute; Pull Testa Tritici out and under 100-110 ℃ of condition, dry, the 4h-5h oven dry;
(2) enzymolysis: papain enzymolysis 1 ~ 2h, the proteolytic enzyme that goes out under 90 ℃ makes starch pasting, high temperature resistant enzymolyzing alpha-amylase simultaneously; The concentration of papoid is 50 ℃ of 1 ~ 3g/L treatment temps, treatment time 1 ~ 2h; High temperature resistant AMS concentration 1 ~ 3g/L, 90 ℃ of enzymolysis time 90min of hydrolysis temperature, enzymolysis is to adding the constant indigo plant of iodine liquid.
