Description

A kind of nano material, its making method and the application in liquor

Affiliated field

The invention belongs to field of new, be specifically related to a kind of nanometer novel material.

Background technology

Nano material is widely used in a lot of industries now as a kind of important material.

And liquor is liked by compatriots deeply as conventional industries of China, especially high-quality liquor.But, the liquor of newly brewageing, its bitter taste, new vinosity and evil assorted smell strange taste such as the strong mud of pungency is smelly, bitterness arranged, so after the liquor of new wine must be deposited for some time, just can reduce gradually, the capital construction and the facility investment of brewery have so not only been increased, prolong the production cycle, caused fund to overstock, and also existed consuming naturally of wine in storage period, the method of this natural aging has directly limited the development of liquor-making enterprise.Therefore adopt the method for artificial aging to shorten the ageing cycle of new wine, be the problem that wine industry is concerned about for these years always; Simultaneously, white spirit is to adopt edible ethanol and the small amount of solid state basic wine that ferments to combine, or goes here and there the edible ethanol that steamed, and carries out the flavouring seasoning with multiple eating spices (essence) or various Wine blending liquid and forms.White spirit is beneficial to and reduces production costs, mouthfeel is favored by a lot of regional human consumers, develop very soon, according to estimates, white spirit output accounts for 70% of national liquor ultimate production, become the important component part of liquor industry, the liquor that white spirit and traditional technology are produced is compared, technology difference not only, and quality also has very big-difference, its shortcoming mainly shows: 1. owing to added a large amount of alcohol, stronger alcohol flavor is arranged.2. the adding of essence makes the floating perfume (or spice) that essence is arranged in the wine, and alcohol and essence can not well associate, and makes the wine body inharmonious, the taste dullness.Improving the white spirit mouthfeel, improve its quality, is the difficult problem of current liquor production technology; In addition, the main component of liquor is the second alcohol and water, be the stronger solution of polarity, contain multiple flavor and fragrance substance composition, senior fatty acid esters such as ethyl palmitate, ethyl oleate and ethyl linoleate wherein are soluble in ethanol and water insoluble, low alcohol white spirit is the liquor of alcoholic strength (v/v) less than 40 degree, because of concentration of ethanol reduces, these solubility of substances reduce, and occur the oyster white molecule in the wine body and liquor is become turbid.Low alcohol white spirit turbidity removal main method has: 1. redistillation; 2. freezing and filtering; 3. absorption method, sorbent material commonly used has gac, starch, diatom scholar, Mierocrystalline cellulose etc.; 4. solubilising method; 5. macroporous resin adsorption etc.Though these method turbidity removal effects are fine, have some shortcomings: as frozen filtration production cost height, facility investment is big; The foam of solubilising method is many, high temperature is turbid again, solid substance is higher etc.; The adsorption time of absorption method is long etc.Though and these methods have removed the high-grade aliphatic ester in the wine, the minimizing of other microcomponents is more, makes the wine body become boring.

Three, summary of the invention

At above problem, the invention discloses a kind of nano material, its making method and the application in liquor.

Nano material among the present invention is that nano level zinc oxide, magnesium oxide, silicon oxide, titanium oxide are mixed in proportion, and this mixture is mixed in proportion with the macromolecular compound polypropylene again, slowly reduces to room temperature and obtain after high-temperature activation compression moulding.

Nano material among the present invention can obtain in the following manner: nano level zinc oxide, magnesium oxide, silicon oxide, titanium oxide are pressed (1-5): 1: 1: mixed (5-1), this mixture is pressed (1-3) with the macromolecular compound polypropylene again: mixed (9-7), through 200-300 ℃ of activation compression moulding after 2-3 hour, slowly reduce to room temperature and promptly obtain, this nano material can be sheet, spherical, strip etc.

It is old that nano material disclosed by the invention can be applicable to improve urging of the turbidity removal of quality, low alcohol white spirit of white spirit and liquor.

The using method of nano material is among the present invention: nano material is placed pending liquor according to a certain percentage, after leaving standstill or stirring certain hour, promptly reach treatment effect.During processing general nano material according in ten thousand/add in the wine to the ratio of 3/10000ths (weightmeasurement ratios), the treatment time was generally 24-168 hour, wherein, for improving the white spirit quality, the general treatment time is 24-72 hour; Turbidity removal and the new vinosity of elimination, bitter taste and evil assorted smell need be handled 24-168 hour according to handling the effect that will reach.

The present invention has the following advantages: 1, can shorten and urge the old time, make the wine body mellow soft, flavour is coordinated, and is sweet refreshing clean, long times of aftertaste; 2, increase the fragrance of wine, improve the quality of wine; 3, effectively turbidity removal becomes high-grade aliphatic ester into colloidal solid, because the existence of the electrostatic double layer on micelle surface, polarity is strengthened, and solubleness strengthens, and these materials still are present in the wine body, makes the low alcohol after thorough clearly low and not light, not loss of gloss.
