Abstract

The invention discloses compound wheat kojis of a kind of yellow rice wine and its preparation method and application.Belong to yellow wine fermentation field.The compound wheat koji of the yellow rice wine produces odor type wheat koji by saccharification type wheat koji and fermentation and forms, and is fermented and is made by rhizopus Q303, Soviet Union 16, bacillus licheniformis and K yeast.Two kinds of wheat kojis are added according to a certain percentage, the yellow rice wine of different pols and alcohol content can be obtained.Gained yellow rice wine high yield amino-acid nitrogen, main body odor type is prominent, and alcoholic strength is higher.It is few compared to traditional wheat koji dosage, high-efficient, vinosity is good.

Description

A kind of compound wheat koji of yellow rice wine and its preparation method and application
Technical field
The invention belongs to yellow wine fermentation field, a kind of compound wheat koji of Novel yellow wine rice and preparation method thereof and yellow rice wine are related generally to Application in production technology.
Background technique
Wheat koji is used as a kind of crude enzyme preparation during brewing yellow rice wine, provides a variety of enzymes and protein, energy for fermentation process Enough it is hydrolyzed the starch in raw material, protein and polymer substance;It can be drinks object that wheat koji, which contains many microorganisms, Matter brings a large amount of wine flavour.
The content of microorganisms and type contained in wheat koji is more, and the nutriment and space in environment are limited, and bacterial strain is often It is unable to normal growth, the saccharifying power in wheat koji, fermenting power etc. is caused to be difficult to reach best simultaneously;Since microbe species are excessively led Cause the harmful substance contents such as the urethanes generated excessively high, amino acid nitrogen content is lower;Flavor components content is more, at Point more miscellaneous, main body odor type does not protrude;Traditional wheat koji since its product is fixed, fix by producer's production model, does not have flexibility;It passes Wheat koji institute expense of uniting is big, and low efficiency is unstable.
Summary of the invention
In order to solve the shortcomings of the prior art, the present invention provides a kind of compound wheat koji of yellow rice wine, by saccharification type wheat koji and Fermentation produces odor type wheat koji composition, is suitble to producer freely to arrange in pairs or groups, meets all kinds of demands.As a kind of wine that pure strain compounds Song, convenient for adjusting the generation of flavor component, harmful substance and increasing amino acid content;, efficiency few compared to traditional wheat koji dosage Height, vinosity are good.
The second object of the present invention is to provide application of the compound wheat koji of yellow rice wine in yellow wine production technology.
To achieve the goals above, the present invention adopts the following technical scheme:
In a first aspect, providing a kind of compound wheat koji of yellow rice wine, odor type wheat koji is produced by saccharification type wheat koji and fermentation and is formed, is prepared Method comprises the following steps:
1) wheat of free from insect pests, mildew is selected, sorting is clean, dries, and makes the moisture content in wheat lower than 15%;
2) wheat in step 1) is crushed using pulverizer, sieves with 100 mesh sieve, saves backup;
3) 30 DEG C inclined-plane culture " rhizopus Q303 " 2-3 days, take flour quality 25%-35% (v/w) nothing in step 2) Bacterium water rinse 2-3 times, the wheat flour in step 2) is added, is sufficiently stirred;
4) it will cultivate 2-3 days at 30 DEG C of wheat flour be sufficiently stirred in step 3), crumb after wheat koji agglomeration, 35-40 DEG C It is dried in baking oven;
5) when the wheat koji water content in step 4) is lower than 15%, pack is spare, obtains saccharification type wheat koji;
6) 30 DEG C inclined-plane culture aspergillus flavus " Soviet Union 16 " 2-3 days, take flour quality 10%-20% (v/w) nothing in step 2) It bacterium water rinse 2-3 times, is added in the wheat flour of step 2), is sufficiently stirred, cultivated 2-3 days at 30 DEG C;
7) 30 DEG C of Liquid Cultures " bacillus licheniformis " and " K yeast " 2-3 days, take the wheat quality 5%- of step 2) respectively 10% (v/w) bacterium solution is spare;
8) it crumbs, the bacterium solution in step 7) is sprayed into the wheat koji after crumbing, 30 DEG C of culture 1-2 after the agglomeration of step 6) wheat koji It, is then placed in 35-40 DEG C of baking oven and is dried;
9) when the wheat koji water content in step 8) is lower than 15%, pack is spare, obtains fermentation and produces odor type wheat koji.
Second aspect provides application of the compound wheat koji of above-mentioned yellow rice wine in yellow rice wine preparation, and the yellow rice wine preparation includes following Step:
1) free from insect pests, the clean rice without mildew, free from admixture is selected to impregnate 12-18h by weight 1:1.5-1:2 and water, Boiling 20min at 108 DEG C takes the sterile water of rice quality 30-50% (v/w) to be cooled down;
2) the saccharification type wheat koji in the compound wheat koji of above-mentioned yellow rice wine of 0.1%-5% step 1) rice quality after cooling is weighed Saccharification step 1) rice after cooling 3-5 days, after fermentation liquid liquid level is consistent with rice height;Weigh 0.1%-5% step 1) Fermentation in the compound wheat koji of above-mentioned yellow rice wine of rice quality after cooling produces odor type wheat koji, is added in fermentation liquid, ferments 5-10 days;
Two kinds of wheat kojis are added according to a certain percentage, the yellow rice wine of different pols and alcohol content can be obtained.
Compared to the prior art, the invention has the following advantages:
1, the compound wheat koji of yellow rice wine has stronger saccharifying power and fermenting power, and the alcohol content of generation is higher;
2, the compound wheat koji of yellow rice wine is as a kind of distiller's yeast that pure strain compounds, convenient for adjusting flavor component, nuisance The generation of matter and increase amino acid content;
3, the compound wheat koji of yellow rice wine is made of saccharifying koji and leaven, is suitble to producer freely to arrange in pairs or groups, is met all kinds of demands;
4, the compound wheat koji of yellow rice wine is few compared to traditional wheat koji dosage, high-efficient, vinosity is good.
