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.

Nature examination
Physicochemical property detection
Physics and chemistry is carried out by " GB/T 13662-2008 yellow rice wine " national standard to the wine sample in example 1-3 after fermentation
Quality detection, number is 1,2,3,4,5 respectively, by traditional yellow rice wine as control:
1. Fig. 1 shows that the saccharifying power of the compound wheat koji of embodiment 1 is higher than traditional wheat koji, and average in 120g/L, compared to biography
The bent 105g/L of system is promoted more;
2. Fig. 2 shows that the alcoholic strength of yellow rice wine made from the compound wheat koji of embodiment 1 fermentation 3-5d in 10%vol, is higher than tradition
The 9%vol of wheat koji;
3. Fig. 2 shows that the amino acid nitrogen content of yellow rice wine made from the compound wheat koji of embodiment 1 can reach 0.62g/L,
It is far longer than the 0.4g/L of high-quality sweet rice wine;
4. Fig. 2 shows that yellow rice wine total acid made from the compound wheat koji of embodiment 1 is slightly above traditional yellow rice wine, belong to the model of sweet rice wine
Farmland;
In addition, by Fig. 3-6 it can be concluded that with it is above-mentioned 1.-4. similar conclusion.
5. the volatile component of yellow rice wine made from the compound wheat koji of embodiment 1-3 is less simultaneously, ethyl propionate, isobutyl are contained only
Alcohol, acyloin, furfuryl acetate, 5 methyl furfural etc. a few, and yellow rice wine made from traditional wheat koji contain a large amount of volatility at
Point, main body fragrance does not protrude.
