Description

Brewing method for improving ethyl lactate content and reducing fusel oil content of rice-flavor liquor
Technical Field
The invention belongs to the field of white spirit brewing, and particularly relates to a brewing method for improving the ethyl lactate content and reducing the fusel oil content of rice-flavor white spirit.
Background
The rice-flavor liquor is prepared by taking rice as a raw material and starter as a saccharification leaven and carrying out solid saccharification, semi-solid fermentation, distillation, aging and blending, and has composite fragrance with ethyl lactate and beta-phenylethyl alcohol as main bodies. Rice-flavor liquor is developed to this day, and is divided into traditional rice-flavor liquor and new-era rice-flavor liquor. Traditional rice flavor type white spirit uses small Chengqing or pottery jar fermentation, and production intensity of labour is big, and is efficient. The novel rice-flavor liquor saccharification and fermentation equipment adopts stainless steel equipment, the stainless steel fermentation equipment improves the sanitary cleanliness of production, reduces the influence of the environment and microorganisms in the equipment, and simultaneously, the novel rice-flavor Xiaoqu adopts pure microorganisms to culture and prepare the qu gradually, and the microorganisms of the qu are relatively simple, so that the fermented rice wine has low ethyl lactate content, low total acid and total ester content, and relatively high fusel oil, so that the typical fragrance of the wine body is insufficient, the taste is light, and the wine is easy to get up after drinking.
Ethyl lactate is a flavor framework component of the rice-flavor liquor, the reduction of ethyl lactate causes the reduction of the quality of the rice-flavor liquor, fusel oil is one of key flavor components of the rice-flavor liquor, but the excessive fusel oil causes the discordance of the liquor body aroma and the bitter taste, and the liquor is easy to be drunk. Therefore, the technology for improving the ethyl lactate content and reducing the fusel oil content of the rice-flavor liquor is very important.
The Chinese invention patent CN106350371A discloses a method for improving the content of ethyl lactate in mechanized white spirit. The main technical scheme is that the fermented grains cooked and gelatinized in a mechanized workshop are cooled, added with yeast, inoculated with microorganisms in a traditional process field, and then loaded into a stainless steel container and put into a fermentation chamber for fermentation. The patent has the defect that the method is limited to the production process of solid white spirit and does not relate to the process of liquid fermentation white spirit.
Chinese patent CN103937642A discloses a method for improving the content of esters and acids generated during the brewing process of white spirit by changing relevant process parameters during the production process of white spirit. However, the method mainly improves acetic acid and ethyl acetate, does not improve ethyl lactate, and is mainly realized by prolonging the fermentation period, wherein the fermentation period is 60-70 days, is only suitable for producing flavoring wine, and is not suitable for producing base wine in large quantities.
Disclosure of Invention
In order to overcome the defects and shortcomings in the prior art, the invention aims to provide a brewing method for improving the ethyl lactate content of rice-flavor liquor and reducing the fusel oil content.
The purpose of the invention is realized by the following technical scheme:

(4) adding fermentation water, rice milk water, acid protease and acid-resistant saccharifying enzyme into the saccharified fermented grains, uniformly mixing, and pumping into a large tank for fermentation at the fermentation temperature of 28-32 ℃;
(5) fermenting for 13-15 days, and distilling the mash to obtain the rice-flavor white spirit with high ethyl lactate and low fusel.
The step-by-step expansion culture of the rhizopus oryzae in the step (2) is carried out by three stages of culture of a triangular flask mold starter, a culture box mold starter and a culture chamber rhizopus bran starter; the triangular flask koji and the incubator koji are obtained according to the conventional method in the field.
The rhizopus oryzae bran koji in the step (2) is preferably prepared by the following steps:
a. mixing bran and 50-55% of water by mass, uniformly mixing, and steaming for 30-40 minutes;
b. spreading and cooling to 30-35 ℃ after discharging, inoculating 0.8-1.0% of yeast, uniformly stirring, and then placing in a yeast room for culture;
c. at the early stage of culture, the culture temperature is 28-32 ℃, the culture humidity is 75-80%, and the culture is carried out for 24-28 hours;
d. in the middle culture period, the culture temperature is 33-37 ℃, the culture humidity is 70-75%, and the culture is carried out for 16-20 hours;
e. after the culture is finished, drying for 8-12 hours at 40 ℃ to obtain rhizopus oryzae bran koji;
the method has the characteristics of short preparation time, simple and controllable operation, and the prepared bran koji has the characteristics of high saccharification force, strong acid production capability, stable fermentation performance and difficult degradation.
In the mixed koji in the step (2), the ratio of the rhizopus oryzae bran koji to the Xiaoqu is 1 (2-4).
Introducing air into the mixture obtained in the step (3), wherein the ventilation volume is 0.1-0.3 m3/m3.min。
In the step (4), the amount of the fermentation water is 100-115%, the rice milk is 10-15%, the acid protease is 0.05-0.1%, and the acid-resistant saccharifying enzyme is 0.1-0.3% by weight of the raw materials.
The principle of the invention is as follows: preparing bran koji from Rhizopus oryzae of the prior art, and mixing with Xiaoqu according to a certain proportion to prepare mixed koji; cleaning part of raw material rice, and then carrying out low-temperature anaerobic soaking to obtain rice milk water rich in lactic acid bacteria; the raw materials are cooked and mixed with the mixed koji for saccharification, certain air is introduced into the bottom of a saccharification tank after the saccharification culture is carried out for a period of time, so that rhizopus oryzae can generate a large amount of lactic acid, the lactic acid is a prerequisite substance of ethyl lactate, and meanwhile, the lactic acid can adjust the pH value of mash and inhibit a large amount of fusel oil from being generated in the fermentation process; adding a certain proportion of rice milk water into the saccharified fermented grains for fermentation, namely inoculating natural lactic acid bacteria for mixed fermentation, generating more acid substances such as lactic acid, acetic acid and the like, and simultaneously reducing the pH value of mash, thereby further promoting the synthesis of ethyl lactate.
