Abstract

The present invention provides Daqu for strong fragrant type Daqu spirits and a production method thereof. The Daqu is prepared from wheat, corn (cassava, sweet potato) powder, wheat bran, beer lees, waste lees, yeast paste, cellar mud functional fungus curing agent, wheat bran rhizopus qu, Aspergillus Niger qu, yeast qu, etc. The present invention has the advantage of short production period, and the present invention saves large numbers of grains for China each year. Therefore, the production cost is reduced, the cost of each ton of qu can be reduced by about 15%, and simultaneously, the esterification capability of the qu to spirits is provided. The spirit quality is effectively improved.

Description

Aroma daqu liquor Daqu and production method

The present invention relates to wine industry, particularly a kind of production method that adopts the non-food crop of part and lose the aroma daqu liquor Daqu of by product making such as being pickled with grains or in wine.

The nature inoculation is all adopted in the production of tradition Daqu, and promptly adopting a small amount of Chinese sorghum of pure wheat or little Meccah or pea to add barley is raw material, makes bent brick, spontaneous fermentation.The technological process of production as the Luzhou Old Cellar yeast wine Daqu of the 21st page of announcement in " the distiller's yeast production practical technique " of publishing by Chinese food press, bent embryo is from going into deep closet to ripe, need one month approximately, production cycle is longer, because adopting food crop is raw material, will consume a large amount of grain every year.In recent years, part brewery has adopted microcomputer posture yeast-making technology, can control automatically the temperature in the whole fermentation process, humidity etc., but yet batching not adjusted.And the Daqu that adopts above method to produce, bent fat ability is lower, thereby has influenced vinosity to a certain extent.

The object of the present invention is to provide that a kind of to adopt the non-food crop of part and lose the poor by product that waits be the production method of the wine Daqu made of raw material, shorten the production cycle, save food, reduce production costs the purpose of raising vinosity to reach.

Solution of the present invention is that the production method of this kind wine Daqu is to comprise that operating weight per-cent is 10～20% wheat-flour, 15～30% corn or cassava or sweet potato powder, 30～35% waste spent grains powder, 20～30% wheat bran, 5～10% brewer's grains, 0.5～1.5% yeast slurry, fixing agent for microorgans in wine brewing mud, each bran husk rhizopus starter, aspergillus niger song, yeast distiller of 0.1～0.5% of 10～30%, and its production process is:

Earlier send out wet with 7～20% 70～85 ℃ water wheat, pile up after 50～70 minutes, be ground into the not plum blossom flap of mashed skin of the mashed heart.With corn or cassava or Ipomoea batatas dry ground, get final product by 20 mesh sieves more than 70%.Lose the poor brewer's grains that reach and after drying, pulverize, to get final product by 20 mesh sieves more than 70%.Select for use and do not have wheat bran, unmetamorphosed yeast slurry, fixing agent for microorgans in wine brewing mud, bran husk rhizopus starter, aspergillus niger song, the yeast distiller that goes mouldy, mix in the iron pan after cleaning in proportion with above-mentioned raw materials, the water of adding 32～38% after stirring, stir once more, make bent brick then, the peace of entering the room behind the cool sweat is bent, through going out song after the cultivation management.

The production method of above-mentioned bran husk rhizopus starter, aspergillus niger song, yeast distiller is by triangular flask enlarged culturing (not boiling of raw material), tray kind song with test tube strains, it is poor to select for use 100% wheat bran, 30～50% to lose, add 60～90% water, inoculum size inoculation with 3～10%, going into the pond ventilation after the uniform mixing cultivated 24 hours, its temperature is controlled at 28～35 ℃, stores with pack behind 40～50 ℃ the hot-air seasoning again.

The invention has the advantages that to have added the non-food crop of part aborning and lost the poor by product that waits, realized losing the poor utilization again that waits by product, can be a large amount of grain of country's saving every year as raw material.Adopt this method to produce the wine Daqu, to going out song, required time only is 7～15 days from the peace song of entering the room, and its fermentation period reduces by more than half, and correspondingly can improve throughput more than one times.Owing to added fixing agent for microorgans in wine brewing mud as the microbial augmentation agent aborning, improved bent fat ability to wine, can improve vinosity effectively.The result shows, adopts this kind method to produce the wine Daqu, and Qu Chengben per ton can reduce about 15%.

Optimum implementation of the present invention is as follows:

Select 3.866 test tube head mold bacterial classifications for use, through triangular flask enlarged culturing (its raw material does not need boiling) and tray kind song, the fresh of rice steamer fresh wheat bran 100%, the same day of selecting for use went mouldy with interior nothing storage period and lost poor 40% at 15 days, the water of adding 80%, with 5% inoculation of wheat bran amount, to go into the pond ventilation after the uniform mixing and cultivated 24 hours, its temperature is controlled at 30 ℃, store with pack behind 45 ℃ the hot-air seasoning then, it is standby to make bran husk rhizopus starter.

Aspergillus niger song and yeast distiller adopt 3.4309 test tube aspergillus niger strains and 2300 test tube barmses to make respectively, and its batching and technology are consistent with bran husk rhizopus starter.

Select wheat 100kg, send out wet with 10kg80 ℃ hot water, rough even back passes holds together to pile up after 60 minutes, and the plum blossom flap of mashed skin (leather that is about to wheat is worn into sheet, the center pulverize) is not stand-by to be ground into the mashed heart.Corn dry method is pulverized, will be lost poor and brewer's grains are pulverized after drying, all get final product to account for 70% by 20 mesh sieves.Selecting for use does not have the wheat bran that goes mouldy again, unmetamorphosed yeast slurry, and fixing agent for microorgans in wine brewing mud, and bran husk rhizopus starter, the aspergillus niger song, yeast distiller etc., in mixing in the iron pan of following ratio after cleaning:

Wheat-flour 16% Semen Maydis powder 20% waste spent grains powder 30%

Wheat bran 25% brewer's grains 8% yeast slurry 1%

Fixing agent for microorgans in wine brewing mud 15% bran husk rhizopus starter 0.2%

The bent 0.3% yeast solid song 0.1% of aspergillus niger

The above-mentioned raw materials back that stirs is added 35% water, stir once more, make bent brick then, the peace of entering the room behind the cool sweat is bent.The starting temperature of fermenting of entering the room is controlled at 20～22 ℃, and the fermentation top temperature is controlled at 54～56 ℃, through going out song after the cultivation management, warehouse-in storage at last.
