Abstract
The present invention relates to a method for preparing wheat alcohol soluble protein, which comprises the steps that an alcohol solution and wheat active protein powder are put into a reaction kettle, the weight ratio of the alcohol solution to the wheat active protein powder is 3 to 5:0.5 to 1.5, the reaction kettle is started to stir, and the temperature of the reaction kettle is gradually raised to 50 to 70 DEG C; after the alcohol solution and the wheat active protein powder are stirred for 6 to 8 hours, the mixture is filtered by a filter, and a filtering liquid is distilled and condensed by an alcohol distillation device to obtain the wheat alcohol soluble protein. The present invention has the advantage of simple technology. The produced alcohol soluble protein product has the advantages of high water resistance and heat resistance, and high grease resistance, and is a green environmental protection raw material which has wide application in a chemical industry and a food service industry. The prepared wheat alcohol soluble protein can be used for an adhesive to replace phenolic resin and urine aldehyde resin, and solves the pollution problem of chemical industrial products of adhesives, glue, etc.
Description
Technical field
The present invention relates to a kind of preparation method of wheat gliadin, relate to the application of wheat gliadin in tamanori simultaneously.
Technical background
As main raw material, in recent years, along with the reinforcement of people's environmental consciousness, burst size of methanal was as weighing the good and bad main standard of product with resol, Precondensed UreaFormaldehyde Resin for tamanori, glue series products at present.Particularly State Bureau of Environmental Protection has been announced new formaldehyde release standard (≤0.07mg/m
3Air), make tamanori, glue class industry be badly in need of seeking the new novel substance that can substitute synthetic resin materials such as resol, Precondensed UreaFormaldehyde Resin.
Summary of the invention
The object of the present invention is to provide a kind of is the method for feedstock production wheat gliadin and the application in tamanori thereof with the wheat active protein powder.
For achieving the above object, the technical solution used in the present invention is: a kind of preparation method of wheat gliadin, in reactor, add spirituous solution and wheat active protein powder, the weight ratio of spirituous solution and wheat active protein powder is 3～5: 0.5～1.5, the unlatching reactor stirs, temperature is risen to 50～70 ℃ gradually, keep after 6～8 hours and filter with the vacuum tank filter, filtered liquid concentrates with the Alcohol distiller distillation and promptly gets wheat gliadin.
Used spirituous solution concentration of volume percent is 70～85%, and the protein content of active protein powder requires to be not less than 60%.
Solid content is at least 20% in the prepared wheat gliadin, and viscosity is greater than 131Mpa.s, and the solid phase prod protein content is greater than 90%.
Wheat gliadin with method for preparing can be applied in alternative resol, Precondensed UreaFormaldehyde Resin in the tamanori.
The consumption of prolamine in tamanori is 30～40%.
Technology of the present invention is simple, and the prolamine product of production has very strong water tolerance, thermotolerance and anti-fat, is the environmental type raw material that purposes is extremely wide in chemical industry and the food service industry.The prolamine that extracts from the wheat active protein powder can replace the resene material to use in tamanori, glue series products as natural plant protein fully, has solved the pollution problem of Chemicals such as tamanori, glue class, added value height, obvious environment benefit.In foodstuffs industry, prolamine can be used as by agent, promptly forms a coating with spray pattern at food surfaces, thereby can moistureproof, anti-oxidation prolongation food shelf-lives.Be sprayed on the fruit, can also increase gloss.The prolamine product that the present invention produces can be directly used in foodstuffs industry, in addition, can also be used for the long-acting cyst membrane of medicine.The present invention provides new application approach for the wheat active protein powder simultaneously.
