Embodiment 1

[0032] Embodiment 1 contains the cultivation method of the serovar serovar fermented liquid

[0033] The specific steps of the method are as follows:

[0034] Pump 390 kilograms of yellow water, 410 kilograms of wine tail, and 170 kilograms of demineralized water into a fermentation pottery jar with a capacity of 1000 liters, add 10 kilograms of crushed Daqu containing the syringa syringae, add 4 kilograms of crushed esterified red yeast rice, Air was introduced for 10 minutes, stirred evenly, and fermented at 32°C for 30 days.

[0035]Fermentation is finished, and fermented liquid color and luster is brown-red, has tea fragrance, floral and fruity fragrance and ester sweetness, sampling, heat distillation, every 500ml fermented liquid steams to obtain distillate 100ml, through gas chromatograph (GC-6890A Lunan instrument) analysis, The contents of ethyl acetate, ethyl butyrate, ethyl lactate and ethyl caproate are as follows: ethyl acetate 0.1538g / L, ethyl butyrate 0.2192g / L...

Embodiment 2

[0038] Embodiment 2 contains the cultivation method of the serovar serovar fermented liquid

[0039] The specific operation steps of the method are as follows: pump 390 kilograms of yellow water, 410 kilograms of wine tail, and 180 kilograms of demineralized water into a fermenting pottery jar with a capacity of 1000 liters, and add 5 kilograms of pulverized CICC 41587 (M9) Daqu, 5 kg of crushed esterified red yeast rice, aired for 10 minutes, stirred evenly, and fermented at 32°C for 30 days.

[0040] Fermentation is completed, and the fermented liquid color and luster is brownish red, has more obvious tea fragrance, floral and fruity fragrance and ester sweetness, sampling, heat distillation, every 500ml fermented liquid is steamed to obtain distillate 100ml, passes through gas chromatograph (GC-6890A Lunan instrument ) analysis, ethyl acetate, ethyl butyrate, ethyl lactate and ethyl caproate content are as follows: ethyl acetate 0.1918g / L, ethyl butyrate 0.2852g / L, ethyl la...

Embodiment 3

[0043] Embodiment 3 contains the cultivation method of the serovar serovar fermented liquid

[0044] The specific operation steps of the method are as follows: pump 390 kilograms of yellow water, 410 kilograms of wine tails, and 190 kilograms of demineralized water into a fermenting pottery jar with a capacity of 1000 liters, and add 20 kilograms of pulverized CICC 41587 (M9) For Daqu, add 6 kg of crushed esterified red yeast rice, let air flow in for 10 minutes, stir evenly, and ferment at 32°C for 30 days.

[0045] After the fermentation is completed, the color of the fermented liquid is brownish red, with obvious tea aroma, floral and fruity aroma and ester sweetness. Sampling, heating and distillation, steaming 100ml of distillate per 500ml of fermented liquid, passing through a gas chromatograph (GC-6890A Lunan Instrument) Analysis, the contents of ethyl acetate, ethyl butyrate, ethyl lactate and ethyl caproate are as follows: ethyl acetate 0.1978g / L, ethyl butyrate 0.291...

Abstract

The invention belongs to the field of a biological technology, and relates to an application of eurotium chevalieri to fermented pit mud microorganism rejuvenation in a Baijiu fermentation pit and a method. Yellow fermenting liquor and last distillate which are generated in the solid-state fermentation of Baijiu are used as main fermentation substrates. The method comprises the steps of adding sterilized softened water, Daqu containing eurotium chevalieri and esterified red yeast rice, performing uniform stirring, inflating air, performing fermentation at 30-35 DEG C for 25-45 days, enabling the obtained fermentation liquid containing the eurotium chevalieri to be led to fermented pit mud in the fermentation pit or unstrained spirits, and performing fermentation, so as to increase the number of anaerobic microorganisms in the fermented pit mud, and effectively realize rejuvenation of microorganisms in the fermented pit mud in the fermentation pit. Besides, the application can also improve the flavor of the fermented pit mud in the fermentation pit, improve the fermentation environment of the unstrained spirits, can further improve the quality of strong fragrance Baijiu of Guojing group, and can improve the flavor of the Baijiu. The Guo brewed fragrant Baijiu having tea fragrance and fruit fragrance can be brewed.

Description

technical field [0001] The invention belongs to the field of biological technology, and relates to the application and method of the fungus schevasin in the rejuvenation of microorganisms in the pit mud of liquor cellars. Background technique [0002] During the brewing process of liquor, the types and quantities of beneficial microorganisms in pit ponds and pit mud have an important effect on the acquisition of high-quality liquor. However, aging of cellar pools and microbial degradation of cellar mud are problems that the liquor industry needs to solve urgently. At present, liquor manufacturers often use supplementary inorganic salts and caproic acid bacteria to rejuvenate the microbial aging and rejuvenation of pit mud, but with little effect. [0003] Chinese invention patent application (CN106085741A) provides a method for cultivating Luzhou-flavor liquor with cellar mud culture solution, which is prepared by using high-quality old cellar mud, extraction mixture, Daqu,...
