Description

Method for preparing rice wine and application thereof
Technical Field
The invention relates to the technical field of rice wine flavor control, in particular to a method for preparing rice wine and application thereof.
Background
Rice wine is a traditional food brewed by Chinese pure grains, and contains various components beneficial to human body, such as protein, vitamins, sugar, trace elements and the like. The traditional rice wine is mainly prepared by taking water and rice as raw materials and brewing through the processes of soaking, steaming, showering cooling, mixing with yeast, saccharification, fermentation, distillation and the like. In the distillation process, the fermented grains volatile substances, water, ethanol, the fragrant components of rice, the fragrant components generated by microbial fermentation, the metabolites of the microorganisms and substances in the external environment jointly form the unique flavor of the rice wine.
In recent years, low-alcohol pre-mixed wines are becoming more popular with young consumers, and most foreign high-alcohol distilled wines such as vodka, brandy and whiskey are used as wine bases of pre-mixed wines. Other foreign highly distilled wines have less acid and ester content in the aroma components, and have the problem of thinner body flavor as a wine base. The organic acid is an important component for forming the taste of the rice wine, and the ester is a substance generated by the reaction of the acid and the alcohol, so that the rice wine has aromatic flavor, plays an important role in the flavor composition of the rice wine, and has the characteristics of mellow, sweet, soft, fine, smooth, plump and long-lasting flavor. Thus rice wine is a better choice as a wine base.
However, the fresh rice wine has bad taste, pungent taste, strong pungency, and bad smell such as pungent taste, rice vinasse taste, mud taste, bitter and wet taste, and is not good for seasoning of the pre-mixed wine. The miscellaneous flavor of the newly-made rice wine is removed, so that the aroma components of the wine base are richer and more various, the taste is softer and more coordinated, long-time ageing is needed after distillation, the production period is long, the space and manpower are occupied for a long time, and a plurality of potential unknown factors influencing the safety and quality of the wine exist, so that the quality of the rice wine is reduced or even damaged, and the mass production of enterprises and the control of the product quality are not facilitated. Therefore, the rice wine is limited in application of pre-mixing as a wine base, and the utilization rate is not high.

The final pre-alcoholic beverage had an alcoholic strength of 3.2% vol, wherein the addition m of the wine base was calculated as follows:
Figure BDA0003939593210000121
②m=ρV;
wherein, a is the alcoholicity of the high alcohol wine, and the unit is vol%;
v-volume of wine per mL;
V 0 -total volume of low alcohol, in mL;
d-alcoholicity of low alcohol in% vol;
ρ is queried according to annex A of GB 5009.225-2016 determination of ethanol concentration in national Standard wine for food safety.
3. Quality identification
The pre-mixed wines prepared by different wine bases are respectively stored in a refrigerator and a normal-temperature light-shielding environment, taken out after 30 days, and respectively subjected to sensory evaluation, and the identification results are shown in table 4.

Figure BDA0003939593210000131
As shown in Table 4, examples 1 to 7 and comparative examples 1 to 5 are low-alcohol white peach flavored alcoholic beverages prepared by using rice wine base, wherein the examples 1 to 7 are good in flavor, taste and overall harmony, and samples stored for 30 days at normal temperature in a dark place have no obvious change in flavor, taste and the like, and are good in stability; the flavor, mouthfeel and overall coordination of comparative examples 1 to 5 were slightly poor, and the samples after 30 days of storage at normal temperature in the dark had slight changes, with unacceptable off-flavors in part. The low alcohol beverage prepared by using the commercial vodka and the edible alcohol has slightly bad flavor and taste, slightly light overall body, better stability and no obvious miscellaneous flavor.
Taken together, the results show that the pre-mixed wine prepared from the rice wine base wine of examples 1-7 is superior to other wine bases in flavor, mouthfeel and stability.
It should be noted that the above embodiments are merely for illustrating the technical solution of the present invention and not for limiting the scope of the present invention, and that other various changes and modifications can be made by one skilled in the art based on the above description and the idea, and it is not necessary or exhaustive to all embodiments. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the invention are desired to be protected by the following claims.
