Abstract
The invention discloses a kind of alkali cleaning agent of stalk dietary fiber, including the sodium hydroxide for pretreatment stage, the ammoniacal liquor for the main hydrolysis stage.The present invention is made up of the Different Alkali of different phase, by carrying out hydrolysis stage by stage to stalk, fully can be discharged glucose from cellulose chain, be improved the hydrolysis degree of cellulose and the yield of carbohydrate.
Description
Technical field
The present invention relates to stalk manufacture field, and in particular to a kind of alkali cleaning agent of stalk dietary fiber.
Background technology
Stalk is the general name of ripe crops cauline leaf (fringe) part.It is often referred to wheat, paddy rice, corn, potato class, rape, cotton
The remainder of flower, sugarcane and other crops (being usually coarse food grain) after harvest seed.The photosynthetic product of crops has
More than half is present in stalk, and stalk is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter etc., be it is a kind of have it is multiduty can be again
Raw living resources.Stalk can be used to pollution-free pulping, prepare dietary fiber and xylo-oligosaccharide.
Containing in stalk in cellulose, hemicellulose and lignin, these three raw materials has winding and wraps between each component
Effect is wrapped up in, further trans-utilization is hindered.If desired stalk is made full use of to do further converted products, it is necessary to stalk
Pre-processed.
The preprocess method of stalk includes Physical and chemical method.Method of chemical treatment mainly includes alkali process and alkali process.
Existing alkali process agent is in processing procedure, and most of hemicellulose is dissolved in aqueous slkali, and reaction speed is quickly, but remaining
Hemicellulose and cellulose insoluble state is then presented, reaction speed is very slow.
The content of the invention
Present invention aims at providing a kind of alkali cleaning agent of stalk dietary fiber, the alkali cleaning agent by different phase Different Alkali
Composition, by carrying out hydrolysis stage by stage to stalk, fully can discharge glucose from cellulose chain, improve the hydrolysis of cellulose
The yield of degree and carbohydrate, part hemicellulose and cellulose can not be dissolved by solving existing alkali cleaning agent, reaction speed asking slowly
Topic.The alkali cleaning agent that the present invention is provided is really the alkali cleaning agent for being used to prepare stalk dietary fiber.
The present invention is achieved through the following technical solutions：
A kind of alkali cleaning agent of stalk dietary fiber, including the sodium hydroxide for pretreatment stage, for the main hydrolysis stage
Ammoniacal liquor.
Sodium hydroxide for pretreatment stage is 2-3wt%.
Ammoniacal liquor for the main hydrolysis stage is 0.2-0.3wt%.
Also include ethanol and glycerine for pretreatment stage.
The volume of ethanol is 3-5 times of sodium hydroxide volume.
Glycerine volume is 3-5 times of sodium hydroxide volume.
Inventive conception is that：Alkali cleaning agent is subdivided into two different phases, it is abundant using highly basic in pretreatment stage
So that stalk is destroyed by alkali so that cellulose, hemicellulose in stalk are acted on by certain predecomposition, then at main point
The solution stage uses weak base, and occupation mode is to carry out the hydrolysis repeatedly of weak base several times so that insoluble hemicellulose and cellulose
It is able to chain decomposition and separation and obtains carbohydrate.
The present invention compared with prior art, has the following advantages and advantages：
The present invention is made up of the Different Alkali of different phase, can be fully from fibre by carrying out hydrolysis stage by stage to stalk
The plain chain release glucose of dimension, improves the hydrolysis degree of cellulose and the yield of carbohydrate, portion can not be dissolved by solving existing alkali cleaning agent
Divide hemicellulose and cellulose, the problem of reaction speed is slow.

Similar with embodiment 3, difference is：Also include ethanol and glycerine for pretreatment stage.The volume of ethanol
For 5 times of alkali volume.Glycerine volume is 3 times of alkali volume.
Embodiment 5
Similar with embodiment 3, difference is：Also include ethanol and glycerine for pretreatment stage.The volume of ethanol
For 4 times of alkali volume.Glycerine volume is 4 times of alkali volume.
Embodiment 6
Similar with embodiment 3, difference is：Also include ethanol and glycerine for pretreatment stage.The volume of ethanol
For 3 times of alkali volume.Glycerine volume is 5 times of alkali volume.
During implementation, pretreatment stage soaks 2-3 in the 170-190 DEG C of sodium hydroxide that stalk is entered to above-mentioned concentration
Hour, in the main hydrolysis stage, the filter residue after processing is put into the ammoniacal liquor of above-mentioned concentration after filtering and soaks 20-30min.
Above-described embodiment, has been carried out further to the purpose of the present invention, technical scheme and beneficial effect
Describe in detail, should be understood that the embodiment that the foregoing is only the present invention, be not intended to limit the present invention
Protection domain, within the spirit and principles of the invention, any modification, equivalent substitution and improvements done etc. all should be included
