In addition, it is pointed out that the operational path of the sye middlings of embodiment of the present invention employing, large moisture is drawn through constantly summing up for many years, is the operational path of posture koji optimum matching.Concrete, in the process of actually operating, can in conjunction with the present invention for embodiment, and carry out the koji operation according to the step in following content:
1, profit grain moisture is large, the time is long, the profit grain time reaches 10-16 hour, and wheat is fully water-swelling under high-moisture, and the enzyme system of wheat self brings back to life, sub-fraction starch is decomposed into sugar under the effect of wheat enzyme system, for the saccharomycetic Fast-propagation of earlier fermentation provides sufficient nutrient.During pulverizing, the wheat of expansion is crushed, and the wheat skin is moisture heavy, becomes soft and can not be chopped up, the wheat heart is pressed into powdery, and a lot of fine powders directly stick to Mai Pishang, so, the common one-tenth of wheat material wheat skin after pulverizing, rare fine powder, the tertia by 40 mesh sieves does not account for 80%~85%.
The degree of grinding of sye middlings, guaranteed that the mould fungi microorganism can take full advantage of the starch that is powdery, grows healthy and strong plentiful mycelia.Simultaneously, because the curved billet that exists of sheet wheat skin can keep the strength of calligraphic strokes and sedimentation preferably, for aerobic microbiological, in the interpolation growth of earlier fermentation amount reproduction and mycelia, provide sufficient oxygen to divide.Also the abundant discharge for fermentation later stage moisture provides " passage ".
2, spice moisture is large, steps on the curved billet water content of making shape and reaches 40%-42%.Curved billet is directly exposed in the middle of air, and moisture distributes comparatively fast, and therefore, embodiments of the invention have increased the water content of curved billet, avoids curved billet fast because of moisture loss, causes moisture deficit, thereby affects the breeding metabolism of microorganism.
3, the fermenting house amount of fetching water is large, and the time of fetching water is long.Curved billet was sprayed on curved billet with the bent mother liquor that has activated after entering the room and fermenting in first 2 days equably, every day 2-3 time, take the humidity that keeps the curved billet surface, reached as the curved billet surface seeding, formed good extension clothing.From curved billet enter that room starts until very the phase finish, every day is water-sprinkling 3-4 time earthward, keeps at any time the humidity on ground, to remain the high humidity state of fermenting house, allow microorganism in curved billet, breed fully metabolism, produce more heat energy, promote the curved billet temperature and further improve, reach higher top temperature.Extended simultaneously the curved billet fermentation in time very, tamed better the beneficial microorganism in the song.The operational path of sye middlings, large moisture, fundamentally solved the bent ubiquitous extension clothing of posture poor, heat up not high, in very short, knee-piece of time harden and do not steep the difficult problems such as gas, fermentation is not thorough.
4, curved billet earlier fermentation, utilize water-sprinkling earthward, on curved billet, sprays bent mother liquor, start the measures such as electrothermal heating line (room temperature below 10 ℃ time), improve temperature, humidity in fermenting house, allow microbial spore under suitable temperature and humidity condition, promptly germinating growth.Generally, in 24h, on visible curved billet, start to produce the needle-like white point, after 48h, complete the extension clothing process of curved billet.In this stage, diligent door window ventilates and changes oxygen, controls the temperature rising, to be no more than 40 ℃, is advisable.After 6 days, the product temperature reaches 60 ℃ (with middle level curved billet thermometer) of top temperature, enters the thermophilic fermentation phase, and curved billet gives out strong fragrance, and therefore, this stage is given birth to the fragrant phase also referred to as high temperature.The thermophilic fermentation phase (subordinate phase) will keep the stability of temperature and higher humidity, and the time of door window humidity discharging can not be long, the moisturizing of often spraying water earthward.
Holding time as 10-12 days of pliotherm period, from the earlier fermentation to the subordinate phase, the temperature of curved billet is the rising state always, and range of temperature is larger, these those length that disappear of the breeding of various microorganisms, kind and the quantity of enzyme are on the increase, the compounds such as the starch in curved billet, protein, fat are under the effect of various microbial enzymes, under higher temperature, humidity condition, through the chemical reaction of series of complex, the a large amount of aromatics of final generation, form compound Qu Xiang.This a series of chemical reaction, in certain temperature range, temperature is higher, and humidity is larger, and it is fierce and complicated that reaction just more is tending towards, and the kind that generates aromatics is also just more.The hot and humid time length is longer, and the growing amount of aromatics is just larger.Multiple a large amount of flavour ingredient and precursor, formed the strong lasting compound bent perfume (or spice) of Daqu and Daqu stronger life fragrant ability in the wine brewing process.After the knee-piece fermenting-ripening, store 3-6 month ability and use, the quality of storage, directly bent style and the quality of impact.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
