Abstract
A method of wood color is adjusted using soybean protein, use the soybean processing byproduct dregs of beans that contains a large amount of soybean proteins as modifying agent, using amino acid abundant in dregs of beans as nitrogen source, it is based on Maillard reaction during heat treatment, deepens wood color and tends to the color of rare tree.The color of the light timber handled by this method is intended to rufous, wherein brightness value L* reduction by 8~15, a* >=4 red green product index variation value △, b* >=6 champac chromaticity index variation value △.The adjusting that soybean protein is applied to wood color is a kind of timber shading process of natural green, and the wood color of acquisition is more uniformly naturally, stability and durability.While promoting timber added value, the difficulty for reducing post-processing also improves the utility value of soybean protein, is a kind of environmental-friendly Wooden modifying mode.
Description
Technical field
The present invention relates to a kind of methods using soybean protein regulation wood color, belong to the skill of the modified aspect of wood color
Art field.
Background technique
China's woodwork yield and volume of trade are in rising trend always in recent years, but wooden resource is increasingly rare, import wood
Material ban more steps up, and country also more payes attention to the protection of the natural green ecological forest, faces these statuses, how to improve timber
Utilization rate becomes a urgent problem to be solved.
The color of timber is to determine the important indicator of product style feature, is the key that evaluation wood surface property and quality
Index is to influence consumer to the direct element of woodwork impression.Market Consumer is biased to purchase rufous material, passes through certain hand
Section, is handled and is regulated and controled to the color of light timber, is a kind of new approaches for solving current problem.
Early in the end of last century, there is scholar's proposition, Maillard reaction can occur during heat_treated wood, bring it about
Brown stain.Maillard reaction is to be found in 1912 by french chemist Mei Lade earliest, refers to the condition in room temperature or heating
Under, the non-enzymatic reaction of a series of complex occurs between amino and carboxyl chemicals, generates the macromolecular substances of brownish black, simultaneously
It is also accompanied by a series of reductones and volatile heterocyclic compounds dregs of beans is resulting byproduct after soybean extracting bean oil, be a kind of
Cheap soy protein source.Currently, about 85% dregs of beans be used to make livestock and poultry feed, also in food, daily use chemicals
And medicine and other fields are utilized.Dregs of beans main component includes 40%~48% protein, 2.5%~3.0% lysine,
0.6%~0.7% tryptophan, 0.5%~0.7% methionine, amino content is abundant, its is from a wealth of sources in addition, and price is low
Honest and clean, excavate to its Exploitative potential has extremely important realistic meaning.It is nitrogen source pair using dregs of beans based on Maillard reaction
Timber carries out impregnation, in conjunction with the means of heat treatment, makes recuding sugars ingredient in timber and dregs of beans during heat treatment
Maillard reaction aggravation, realize that the color of timber is oriented regulation, improve its visual characteristic to a certain extent, enhancing is wooden
The decorative effect of product promotes the utility value of timber and dregs of beans.
Summary of the invention
The purpose of the present invention is intended to provide a kind of method using soybean protein regulation wood color.This method operation letter
Just, low in cost, it is easy to operate, effectively regulate and control the color of timber, improves the utilization rate of timber.Skill of the present invention
Art scheme are as follows: a method of regulate and control wood color using soybean protein, the specific steps of which are as follows:
(1) a certain amount of dregs of beans and water are taken, mixed liquor is configured to for 1:1~1:20 with mass ratio, acquired solution is placed in
5~10min is handled in ultrasonic vibration machine.
(2) select it is corrosion-free, without discoloration, light solid wood board uniform in material, after being polished with sand paper, sawing one
Scale cun, the good plate of sawing is placed in vacuum reaction kettle.
(3) configured soy bean proteinous soln is injected in vacuum reaction kettle, 12~36h of impregnated plate.
(4) vacuum reaction kettle restores normal pressure state, takes out plate, places it in the environment of ventilation and spontaneously dry, and removes
The residue of wood surface.
(5) the timber uniform coding in (4) is placed in high-pressure steam sterilizing pan, it is carried out with saturated vapor heating 2~
12h。
In step (1), used water should be distilled water, under room temperature, should be noted that in entire soaking process
It avoids introducing other chemical components.
In step (2), vacuum degree is 0.4~0.8MPa, and solid wood board used can be quick growth poplar wood, Eucalyptus, pine
One of wood.
In step (3), soy bean proteinous soln should be totally submerged plate.
In step (5), heat treatment temperature is 100~150 DEG C, and pressure is 0.08~0.32MPa, and heating rate should control
Within the scope of 2~4 DEG C/min.
Compared with prior art, the present invention has the following advantages and effects:
1, in entire modifying process, common dregs of beans is used, has widened its utilization scope, improves its use
Value, the energy problem to solve current provide a new approaches.
2, using Maillard reaction, the orientation of wood color is regulated and controled, the color of light timber is more towards Market Consumer
The favorite rufous of institute, wherein brightness value L* reduces by 8~15, red green product index variation value △ a*>=4, champac chromaticity index becomes
B* >=6 change value △.For the means such as common coating and dyeing, resulting color is more uniformly naturally, and due to raw material source
In naturally, more Environmental Safety.
3, the preparation method is timber drying one pretreatment, and easy to operate, inexpensive is easily controllable, has
Certain promotional value has certain realistic meaning for solving current timber supply and demand contradiction.
