Abstract
A composite material containing tannin used for beer, fruit wine, yellow wine, etc features that the tannin is linked or polymerized to the surface of carrier particle by polyepoxy cross-linking agent. It can improve stability and elongate quality guarentee period.
Description
The present invention relates to be used to handle the material that contains alcoholic beverage, more particularly, is a kind of matrix material that contains tannin.
Vegatable tannin is applied to the existing history that goes up a century of liquor industry.In recent years, in order to improve its effect, the someone studies the manufacture method of high purity tannin, discloses a kind of method of production high purity Weibull as Chinese patent ZL96104795X.The high purity tannin can be used for processing and contains alcoholic beverage, remove macromolecule protein wherein, thereby improved the non-biostability that contains alcoholic beverage, prolong the freshness date and the quality guaranteed period that contain alcoholic beverage, the effect highly significant, but exist the imperfection part on some applied links, for example, the wheat juice that is applied to beer production is handled, when Wort boiling, add, can remove some macromolecule proteins, but albumen-tannin throw out is difficult to sedimentation, therefore satisfactory not to the utmost to wheat clarification of juice effect; The difference, the factors such as difference on the different production batch beverage quality that contain between the alcoholic beverage kind are all influential to the effect of high purity tannin, make that the application of high purity tannin on producing is wayward, and fixed tannin head it off preferably.Past is difficult to realize industrialization, so the fixed tannin product does not also occur on the market owing to the production method more complicated of fixed tannin.
But the fixed tannin product that the purpose of this invention is to provide the simple suitability for industrialized production of a kind of production method promptly contains the matrix material of tannin.
Main technical schemes of the present invention: by poly-epoxy crosslinking agent tannin is connected with carrier granule or polymerization in carrier particle surface, make the immobilized purpose of tannin thereby reach.
Matrix material component of the present invention and content thereof (is 100 in the matrix material dry weight):
Water-insoluble material granule 30-80%, the best is 45-70%; Tannin 10-45%, the best is 25-45%; Poly-epoxy crosslinking agent 1-25%, the best is 5-15%.
Water-insoluble material of the present invention is the carrier of matrix material, and it is selected from inorganic materials, natural macromolecular material, synthesized polymer material or their mixture, and its granularity is less than 50 orders, and the best is the 600-300 order.Described inorganic materials comprises titanium dioxide, aluminum oxide, perlite or their mixture; Described natural high moleculer eompound comprises cellulose powder, chitin, Microcrystalline Cellulose or their mixture; Described synthetic macromolecular compound comprises polyethylene, polypropylene or their mixture.The density of above-mentioned materials is different, and the fixed tannin pellet density of selecting for use different carrier granules to obtain has bigger difference, so the present invention can develop a series of fixed tannin product, is suitable for the different links of using, to reach best effect.
Poly-epoxy crosslinking agent of the present invention is the C4-C12 diglycidyl ether, refuse to take a passenger body particulate character and different of its consumption.When carrier granule is titanium dioxide, aluminum oxide, perlite, polyethylene, polypropylene etc. when not containing the active reactive group particle, the consumption of poly-epoxy crosslinking agent is preferably 8-15%; When carrier granule is cellulose powder, chitin, Microcrystalline Cellulose etc. when containing the particle of hydroxyl activity reactive group, poly-epoxy crosslinking agent consumption is preferably 5-10%.
Tannin of the present invention is a vegatable tannin, comprises condensed tannin and Hydrolysable Tannins, preferably selects Hydrolysable Tannins for use, and the preferred Chinese tannin of the present invention is particularly selected the high purity Chinese tannin for use.
The preparation method of matrix material of the present invention: carrier granule, tannin, poly-epoxy crosslinking agent are placed solvent, mix, and make tannin and poly-epoxy crosslinking agent dissolving, and regulate PH to 9-10, be heated to 120-180 ℃, reacted 3-5 hour, reaction is cooled to room temperature, the filtered and recycled solvent after finishing, wash product and drying-granulating with water, promptly obtain the composite material granular product.
Described solvent is selected from water, dimethyl sulfoxide (DMSO), dimethyl formamide equal solvent or its mixed solvent, preferably water, its consumption with just all the insoluble material granules of soakage water be advisable.
The method that composite material granular of the present invention is applied to contain alcoholic beverage is equal to the application method of the high-purity tannin that uses in brewageing, and promptly composite material granular joins in containing the production process of alcoholic beverage and contains in the alcoholic beverage, and removes before beverage bottling.
Major advantage of the present invention: production method of the present invention is fairly simple, used raw material all is that market is bought, product application of the present invention is in ethanol class beverages such as beer, fruit wine, yellow rice wine, can improve their non-biostability and flavor stability, and can prolong its quality guaranteed period and freshness date, the application of this product is more convenient.
Further specify characteristics of the present invention below by specific examples.
Example 1
1000 gram Chinese tannins, 550 gram ethylene glycol diglycidylethers, 3000 gram titanium dioxide are placed 2000 gram pure water, mix, with 10% potassium hydroxide regulation system pH value to 10, be heated to 120 ℃ of reactions 5 hours under constantly stirring, be cooled to room temperature, wash with water, at last with the product drying-granulating.This example product density is bigger, is applicable to the proteic occasion of rapid subsidence.
Example 2
With 800 gram Chinese tannins, 350 grams 1,4-butanediol diglycidyl ether, 2000 gram titanium dioxide place the mixed solvent (pure water: dimethyl formamide=1: 1) of 1000 gram pure water and dimethyl formamide glue, mix,, stir and be heated to 140 ℃ of reactions 3 hours with 10% sodium hydroxide regulation system pH value to 9.5, reduce to room temperature, the filtered and recycled solvent washes product with water, at last with the product drying-granulating.
Example 3
1000 gram Turkey-galls gram tannin, 100 gram ethylene glycol diglycidylethers, 1100 gram cellulose powders are placed 2000 gram pure water, mix, with 20% sodium hydroxide regulation system pH value to 10, be heated to 130 ℃ of reactions 3 hours under constantly stirring, be cooled to room temperature, wash with water, at last with the product drying-granulating.This example product density is less, can guarantee and contain that albumen fully acts in the alcoholic beverage, but settling velocity wants slow than the product of example 1.
Example 4
The product application that obtains in the example 1 is handled in the wheat sweat of beer production, added when wheat sweat boils, add-on is that wheat juice per ton adds the composite material granular that 150 gram examples 1 obtain, and makes the Partial Protein in the wheat juice form precipitation rapidly, clarification wheat juice.
