Abstract
The invention discloses a kind of pits to conserve nutrient solution.Its raw material includes Koji, yellow water, and raw material further includes pit mud, foreshot, liquor tailing, bottom grain.Pit maintenance nutrient solution produced by the present invention has good effect for formation, the continuity of pit flavor substance.
Description
Technical field
The present invention relates to a kind of biotechnologys, and in particular to a kind of pit maintenance nutrient solution.
Background technique
In liquor production, the quality of pit has an important influence the quality of wine, the activity, quantity of microorganism in pit,
The factors such as content, the pit pH of harmful substance determine the quality of this pit, it is therefore desirable to periodically conserve to pit.Existing skill
The application documents of Publication No. 107057911A disclose a kind of pit maintenance process in art, it is disclosed that " shield cellar: going out grain
Afterwards, Jiao Bi is washed, then smears the juice that pear, apple, yellow water, wine and Koji mix in pit surrounding, smears two
Sprayed after secondary ", using the curing fluid that this is formulated, only for the moist environment that provides in wine cellar, in the Koji being newly added
The survival rate of microorganism is not high, and the formation effect for wine cellar flavor substance and bad.
Summary of the invention
The purpose of the present invention is to provide a kind of pits to conserve nutrient solution, solves existing pit maintenance for pit flavor
The formation and the bad problem of holding of substance.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of pit maintenance nutrient solution, raw material include Koji, yellow water, and raw material further includes pit mud, foreshot, liquor tailing, bottom grain.Cellar
Type containing all microorganisms contained by former pit in mud, the ratio of these microorganisms determine unique wind of the pit
Taste, therefore it is significant for the continuity of pit flavor that pit mud is added.Foreshot is to cut the wine evaporated at distillation initial stage, and Alcohol degree is very
Height, wherein these flavor substances are generated by microorganism there are also the more liquor flavor substance formed, these flavor substances battalion
The growth for also instead promoting microorganism for the environment made.Liquor tailing acidic substance content is high, and acid is to form Luzhou-flavor liquo fragrance
Precursor, therefore can use the acidic materials in liquor tailing.Cellar bottom grain unstrained spirits is commonly called as the produced vinosity of bottom grain, is entire pit
Middle flavor part the strongest, is added bottom grain, and flavor when for continuous production has a major impact.Therefore the formula from
The reservation of microorganism, the growing environment of microorganism angularly consider there is good effect to the flavor formation of wine, continuity.
Preferably, in parts by weight, the pit mud is 150~200 parts, Koji is 20~50 parts, yellow water 60
~100 parts, foreshot be 45~55 parts, liquor tailing is 90~105 parts, bottom grain is 28~35 parts.Wherein the ratio of liquor tailing is important, because
That excessively it will cause acidity is excessively high for liquor tailing middle acid substance, can inhibit the production of saccharomycete, and if acidic materials are very few, a side
Face causes the precursor of Luzhou-flavor liquo fragrance matter insufficient, and the too low prior fermentation that will cause of another aspect acidity is too quickly, rises
Sour amplitude is excessive.
Preferably, in parts by weight, the pit mud is 150~200 parts, Koji is 20~50 parts, yellow water 60
~100 parts, foreshot be 45~55 parts, liquor tailing is 90~105 parts, bottom grain is 28~35 parts.
Preferably, the pit mud is that microorganism using the pit mud in 30 years or more pits, in pit mud is more steady
It is fixed, it is more stable for the continuity of flavor.
Preferably, a kind of pit conserves nutrient solution, includes the following steps and is made:
S1 mixing: the raw material is uniformly mixed；
S2 fermentation: the raw material after mixing is fermented in sealed environment.Spray is not applied after raw material is mixed not instead of directly, is first carried out
Fermentation, fermentation is so that the microorganism in pit mud more adapts to environment, and conducive to stablizing, while fermentation process is what microorganism grew
Process improves content of microorganisms in nutrient solution.
Preferably, fermentation temperature is 30~35 DEG C in the S2 fermentation step, fermentation time is 25~35 days.Oneself
Acetoacetic ester is the main flavor substance of Luzhou-flavor liquo, which is conducive to generate the growth of the caproic acid of ethyl hexanoate.
Preferably, further including sodium acetate in the raw material, after adding sodium acetate, advantage is presented in the quantity of caproic acid bacteria,
And the microbial activity enhancing in nutrient solution, the lipid fragrance matter based on ethyl hexanoate is more enriched, promotes aroma.
Preferably, further including cellulose, pectin in the raw material.Cellulose be by glucose group at macromolecular it is more
Sugared that carbon source on the one hand can be provided for caproic acid bacteria, another aspect cellulose is met water and is swollen, and has good moisture retention, and fine
There is bigger surface area after dimension element swelling, provide implantation for microorganism, be conducive to microorganism and grow.Pectin has gelatification,
So that the nutrient solution has centainly viscous stickiness, convenient for being adhered to pit without loose.
Preferably, in parts by weight, the pit mud is 150~200 parts, Koji is 20~50 parts, yellow water 60
~100 parts, foreshot be 45~55 parts, liquor tailing is 90~105 parts, bottom grain is 28~35 parts, 0.2~0.5 part of cellulose, pectin
0.05~0.15 part.
Preferably, being continually fed into carbon dioxide into raw material when the described S1 mixing step.It is passed through one side of carbon dioxide
Oxygen can be discharged in face, on the other hand form hole, provide more spaces for the growth of microorganism, be distributed more uniform.
Compared with prior art, the beneficial effects of the present invention are: pit produced by the present invention conserves nutrient solution for pit
The formation of flavor substance continues with good effect；The present invention is conducive to the growth of pit microorganism, the especially life of caproic acid bacteria
It is long；The present invention provides implantation for microorganism, and is adhered to pit without loose.
