Specific embodiment
Specific embodiments of the present invention are further elaborated below.It should be understood that herein to the present invention
The explanation of embodiment is not intended to limit the scope of protection of the present invention.
The ramie soak for ramie raw materials degumming comprising the fat that mass percent is 0.5%~5%
The sodium alkyl sulfonate that alcohol polyoxyethylene ether and mass percent are 0.5%~2%, remaining is water.The aliphatic alcohol polyethenoxy
Ether is also known as polyoxyethylene aliphatic alcohol ether, is the ether as made of polyethylene glycol (PEG) and fatty alcohol condensation, use following general formula
Indicate: RO (CH2CH2O) nH, wherein n is the degree of polymerization, is had not because the degree of polymerization of polyethylene glycol is different with the type of fatty alcohol
Same kind.The fatty alcohol polyoxyethylene ether is characterized in that the ehter bond in molecule is not easy to be destroyed by acid, alkali, so high stability,
Water-soluble preferable, electrolyte-resistant is readily biodegradable, and foam is small.Sodium alkyl sulfonate is a kind of chemical substance, anion table
There is the sulfonic group of a strongly hydrophilic to be linked with alkyl in the active agent molecule structure of face, surface-active is strong, low temperature water-soluble
Good, 2U DEG C contains 32% active matter.When impregnating the ramie raw materials, the temperature of the ramie soak serve it is conclusive, because
This in the present invention, when impregnating the ramie raw materials, the temperature of the ramie soak should be maintained at 95 DEG C~100 DEG C.
In order to which the better immersion effect reached is more advantageous to the degumming of follow-up process that is, so that the ramie is looser, it is preferable that institute
State fatty alcohol polyoxyethylene ether of the ramie soak for ramie raw materials degumming also containing mass percent 1%~1.5% and
0.25%~1.25% sodium alkyl sulfonate.Fatty alcohol polyoxyethylene ether is strong bleeding agent, can be used for various waxes, alternating
Emulsification, the dispersion of substance, prevent from adhering to；Sodium alkyl sulfonate belongs to anionic surfactant, have excellent infiltration, washing,
Wetting, decontamination and emulsification.The two uses simultaneously, has synergistic effect, greatly improves immersion efficiency, mention for post-processing
For good basis.In the present embodiment, the ramie soak contains the aliphatic alcohol polyethenoxy of mass percent 1.5%
Ether and 0.75% sodium alkyl sulfonate.Fatty alcohol polyoxyethylene ether and sodium alkyl sulfonate decontamination, emulsifying effectiveness under high temperature environment
Than increasing by 20 times under room temperature, in ramie soaking process, soak is heated near boiling point, immersion effect can be strengthened, subtracted
The dosage of few fatty alcohol polyoxyethylene ether and sodium alkyl sulfonate, saves raw material, reduces cost.Therefore, the ramie raw materials are 98
DEG C ramie soak impregnates 8h, then is more advantageous to degumming.
The combination of enzyme preparations object for ramie raw materials degumming, is grouped as by each group of following mass percent:
25%~45% pectase, 15%~20% zytase, 10%~15% mannase, 5%~15% mouse
Lee's glycosidase, 20%~25% auxiliary agent.The pectase, which refers to, decomposes plant main component-pectic substance enzyme.Pectase
It is distributed widely in higher plant and microorganism.Xylan (xylan) be it is a kind of be present in it is heterogeneous more in plant cell wall
Sugar accounts for about the 15%~35% of plant cell dry weight, is the main component of plant hemicellulose.Zytase is in nature point
Cloth is extensive, can obtain from animal, plant and microorganism.Zytase can be applied in brewing, feed industry.Xylan
Enzyme can decompose raw material cell wall and beta glucan in brewing or feed industry, reduce the viscosity of material in brewing, promote
The release of active principle, and the non-starch polysaccharide in feed-use grain is reduced, promote being absorbed and utilized for nutriment, and thus
It is easier to take soluble lipids ingredient.Mannase, that is, the 'beta '-mannase is a kind of multi-functional growth accelerator, can be with
Promote the secretion of quasi-insulin growthing factor I GF-I, promotes growth.Rhamnose, also known as 6-deoxy-L-mannose are to deposit extensively
It is one of polysaccharide, glucosides, natural plant gum and the bacterial polysaccharides of plant substance.Preferably, described to be used for ramie raw materials degumming
Combination of enzyme preparations object be grouped as by each group of following mass percent 30% pectase, 20% zytase, 10%
Mannase, 15% rhamnosidase, 25% auxiliary agent.The auxiliary agent is grouped as by each group of following mass percent:
40%~60% lauryl sodium sulfate, 25%~40% sodium tripolyphosphate, 10%~20% polysorbas20.Described ten
Sodium dialkyl sulfate is dissolved in water for white or faint yellow powdery, insensitive to alkali and hard water, and have decontamination, emulsification and
Excellent foaming power.The polysorbas20 is sorbierite and one dehydration, double dehydration compounds and laurate by every mole of sorb
Alcohol and its anhydro compounds and about 20 moles of ethylene oxide are condensed under alkaline condition and are made.In the present embodiment, institute
Auxiliary agent is stated to be grouped as by each group of following mass percent: 50% lauryl sodium sulfate, 30% sodium tripolyphosphate,
20% polysorbas20.Experiment many times shows effectively help ramie to slough part colloid with pectase and zytase,
But always have some remnants.Inventor has surprisingly found that in experimentation, when rhamnosidase and pectase, xylan
Simultaneously in use, after the long period, colloid is almost disposed of entirely for enzyme, mannase.It has been recognised by the inventors that ramie
In the colloid of raw material, containing the nonhydrolyzable substance such as pectase and zytase, and these substances can be by rhamnosidase
It is degraded, these four enzymes use simultaneously, can play synergistic effect, fully erased colloid.Lauryl sodium sulfate,
Sodium tripolyphosphate and polysorbas20 are excellent dispersing agents, these auxiliary agents are used together with enzyme preparation, can make ramie raw materials
More enzyme preparation action sites are exposed, promotes the combination of enzyme preparation and these sites, effectively accelerates the effect of enzyme preparation,
Enzyme preparation dosage is reduced, cost is reduced.
A kind of Degumming method for ramie raw materials comprising following steps:
S1: preparing ramie soak, which includes the fatty alcohol polyoxy that mass percent is 0.5%~5%
