Description

A method of improving river method distilled liquor quality
Technical field
The present invention relates to a kind of production methods of white wine.Especially a kind of method for improving river method distilled liquor quality.
Background technique
" Sichuan Xiaoqu liquor " is with a long history, is liked deeply in southwest, Central-South each province, according to incompletely statistics, annual output about 70 Ten thousand t, Sichuan account for 50% or so.Conventional solid-state method Chinese yeast is mainly with the sorghum of this real estate, corn, wheat, buckwheat, barley, highland barley Deng for raw materials for production.The production method main processes of conventional solid-state method Chinese yeast include: under bubble grain-steaming grain-spreading for cooling- Song-closing heap-culture saccharification-outlet-is with grain --- and pit entry fermentation-goes out pond distillation, and the sort of quyi used is single rhizopus.Tool There is the features such as small investment, quick, flexibility is high;Be produced in situ in, market goods locally, lose grain by local peasant household be used as feed, Advantage without the pollution for discarding grain.Various alcoholic drink mixed with fruit juice (health liquor) are prevailing in recent years, and making base liquor production health liquor with distilled liquor is It is traditional, and generally acknowledge best, this is the incomparable advantage of other aromatic white spirits.According to expert estimate distilled liquor half with The upper base liquor as other alcoholic drink mixed with fruit juice of production or other odor type wine, expands demand of the market to distilled liquor, further promotes The development of distilled liquor.Application with modern raw technology in wine brewing with the development of science and technology, it has been found that in distiller's yeast The bent or full cell of addition esterification is esterified inulinase and the fragrance and mouthfeel of distilled liquor can be improved, such as Chinese patent 20161015601.x A kind of disclosed barley monascus prepared wine and its preparation process use highland barley monascus 1-5 parts by weight, esterification song 0.1-0.5 weight Amount part mixes immersion with 38-60%vol brewing grains white spirit 35-500 parts by weight and is made.For another example Chinese patent 201510777729.4 is public A kind of spirit distiller grain distiller's yeast and liquor brewing method, distiller's yeast opened are made of following component, and high activity dedicated grape of making wine forms sediment 30-50 parts of powder enzyme, 30-45 parts of Rhizopus bran koji, 5-15 parts of yeast distiller, 1-10 parts of Bai Qu, high temperature resistant high activity saccharomyces cerevisiae 1-6 Part, 1-6 parts of high activity aroma-producing yeasts, full inulinase 1-5 parts of cell esterification, 1-5 parts of acid protease, 1-5 parts of cellulase, medium temperature 1-3 parts of alpha-amylase.Technique using discarding arrack Qu Jinhang brewing includes abandoning grain cooling, abandoning arrack song mixed powder It is broken, lose the activation of arrack song, it is lower it is bent, enter pond, fermentation, steam wine step.Though foregoing invention can partially improve white wine to a certain extent Fragrance and mouthfeel, but due to being esterified bent dosage and time upper Shortcomings, effect is unsatisfactory, to Sichuan Xiaoqu liquor work Skill is less applicable in.
Summary of the invention
Do not change it is an object of the invention to overcome the deficiencies of the prior art and provide one kind and improves river on original Process ba- sis Method Xiaoqu wine flavor component content increases the method for the raising river method distilled liquor quality of the mellow sense of fullness of product.Of the invention Purpose realized by following technical proposals, a method of river method distilled liquor quality being improved, including traditional river method Chinese yeast Bubble grain, steaming grain, spreading for cooling, lower song in white wine solid state process, the rhizopus of 0.3% weight of addition raw grain total weight are received after mixing thoroughly Culture saccharification 20-24 hours after heap, closing heap, outlet, press grain: grain is 1:3 with poor, preparation esterification song or commercially available esterification are bent, match grain When to be added esterification bent, be added in two portions, additional amount is the 0.7-0.9% of raw grain total weight, enter 25-35 DEG C of pond fermentation 7-10 days, Finally go out pond distillation according to a conventional method, collects wine and enter altar.
The preparation esterification is bent, and steps are as follows:
(1) strain improvement, the monascus specie for selecting commercially available esterification function strong or separates strain from the high-quality sort of quyi, specific side Method is that wort agar medium is added in plate, is cooled to room temperature after high pressure sterilization, is inoculated with method of scoring, 32-35 DEG C of training Support 4-5 days, pick out bacterium colony just at white, it is aging after become red, mycelium have a large amount of branches, branch top generate individually or Bunchiness conidium, spore are rounded or oval bacterium colony makees strain;
(2) pass through 32-35 DEG C of heaven-made first class inoculum of culture 5-7 of wort agar test tube slant culture medium;
(3) esterification strain expands culture and expands culture the triangular flask bacterial being separately cultured, and carries according to Spawn incubation is common Body, selects rice or wheat bran as culture medium, is connect through high pressure sterilization when temperature is down to 35 DEG C with lactic acid adjustment pH to 3.5-5 Enter higher level's strain, carries out culture 5-7 days under the same conditions;
(4) it is esterified bent Ventilated bed culture, wheat bran+water to hand is pinched agglomerating, release and dissipated, and is put into rotary spherical digester and carries out high pressure sterilization, mechanical It turns, is cooled to 40-35 DEG C of inoculation after rotary spherical digester out, secondary agitation is uniform after inoculation, sets room culture, and centre turns over song one for 4 hours Secondary, it is finished product wheat bran that room sunning is gone out after 6-7 days, is stored after biochemical investigation is qualified spare.
Addition esterification song is completely suitable for the fermentation of faint scent type white wine in the present invention, and application method is also very simple, does not change Become respective production technology, do not increase manufacturing facilities, does not increase labor intensity.Different batches test result is shown: esterification song exists Application in Xiaoqu liquor by solid fermentation production, is significant to Chinese yeast base liquor quality effect is improved.Addition opportunity is also very crucial, through more It is advisable in secondary small lot, pilot scale and production using addition when showing esterification song to unpack with unstrained spirits.Addition esterification is bent, bent by esterification Bacterium constantly generates Esterified Enzyme, and can make stabilizing and increasing for ethyl ester substance: testing result shows ethyl acetate and ethyl lactate all With raising relatively stable and by a relatively large margin, this has played decision to the quality for stabilizing and increasing Chinese yeast faint scent white wine base liquor and has made With.From the point of view of mass production application, acid is richer, and acetic acid increasing degree is larger, normal propyl alcohol from the point of view of the variation of alcohols material, The variation of isoamyl alcohol is exactly the opposite.Lab scale, pilot scale, mass production stage are almost the same.Product of the present invention by 1 country by being commented Committee, 3 group's appraises of tasting and appraising for saving judging panel, 1 our factory technical staff composition are thought: wine aroma nature, pure elegant, wine body It is pure and mild, sweet ice-cold net refreshing, there is Xiaoqu wine typical style.Meet the requirement of " 26761 Chinese yeast white spirit by solid state method of GB/T ".Through trying Pin, average price improve 20% or so, deep to be liked by local consumer, remarkable in economical benefits.
