Description
Technical field
The present invention relates to a kind of wheat rich in araboxylan (or pentosan) produced as raw material with wheat bran
Polysaccharide drink and its production method.
Background technology
Wheat bran is large accessory substance of wheat flour milling processing, and China is as wheat main product and consumes big country, every year about
There is 20,000,000 tons of wheat bran resource.Wheat bran is high-quality dietary fiber sources generally acknowledged both at home and abroad, wherein main meals
The food fibre composition composition such as including cellulose, hemicellulose, lignin.Wherein hemicellulose is with araboxylan (or penta
Glycan) based on, it accounts for more than the 60% of wheat bran dietary fiber composition.Include this laboratory early-stage Study table both at home and abroad
Bright, the araboxylan in wheat bran source is a kind of important functional polysaccharide, and it has bioactive polysaccharide normal simultaneously
See such as relax bowel, reducing blood lipid, Immune-enhancing effect physiological function.But, naturally occurring Arabic wood is poly- in wheat bran
Sugar more than 90% exists with water-insoluble state, and its functional activity then needs under water soluble state competence exertion out, therefore
Araboxylan in wheat bran is separated from insoluble fibre substrate, soluble polysaccharide is changed into and is just seemed ten
Divide necessity.
Mostly be to prepare wheat-bran dietary fiber by raw material of wheat bran in domestic disclosed patent, such as " wheat bran it is multi-functional
The extracting method (200410006552.x) of conversion-dietary fiber ", " the multienzyme method of fractional steps prepares the side of wheat bran food fibre powder
Method (200510019123.0) ", " a kind of method (200610024903.9) of extraction of multifunctional diet fibre from wheat bran ",

The preparation method (201010185365.8) of fiber ", " a kind of method that utilization wheat bran prepares dietary fiber
(201110152252.2) " etc., product is mostly insoluble dietary fiber.Also some patents relate to the use of enzymolysis process from small
Araboxylan (or pentosan) or xylo-oligosaccharide, such as a kind of " separation system of Wheat Bran Pentosans are extracted in wheat bran skin
Preparation Method and application (200410014376.4) ", a kind of " method of preparing feruoylated oligosaccharide by enzymolysis of wheat bran
(200610037952.6) ", " a kind of method of preparing xylo-oligosaccharide by enzymolysis of wheat bran (200610037953.0) ", " one kind
Using extruding method (200710135300.0) of the assisted enzymolysis wheat bran for xylo-oligosaccharide ", " wheat bran enzyme engineering method
The method (200910064898.8) of conversion pentosan and dietary fiber ", a kind of " side of preparing feruloyl oligosaccharides by wheat bran fermentation
Method (201110060123.0) ", " a kind of method (201210371793.9) that xylan is extracted from wheat bran " etc., adopt more
Its dissolubility is improved with the zytase or pentosanase that can hydrolyze araboxylan, or using amylase, albumen
The interfering material such as starch, protein in enzyme removal wheat bran, final goal be in order to obtain a kind of araboxylan or
Raw material rich in araboxylan.Also once using alkaline process (NaOH, KOH etc.) from wheat bran in this laboratory previous research work
Skin extracts the soluble araboxylan for obtaining higher degree (>=60%), and has proven to the Arab in macromolecular state
Xylan have significant immunological regulation (there is the antitumor wheat bran polysaccharide with immunoregulatory activity and its extracting method,
ZL200910237352.8), prebiotic activity.
On the basis of early stage numerous studies, this patent proposes that a kind of wheat bran is preprocessed and weak acid hydrolysis is improved and produced
The method of araboxylan dissolubility and content in product, and a kind of wheat polysaccharide rich in desired polysaccharide is developed on this basis
Beverage products, it is intended to for the increment conversion of wheat bran provides technical support.
