The contrast of physical and chemical index
In addition, it is pointed out that the sye middlings that the embodiment of the present invention adopts, the operational path of large moisture is through constantly to sum up for many years and draws, 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 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 abundant 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 wheat skin is moisture heavy, becomes soft and can not be chopped up, the wheat heart is then pressed into powdery, and a lot of fine powder directly sticks to Mai Pishang, so, wheat material common one-tenth wheat skin after pulverizing, rare fine powder, does not account for 80% ~ 85% by the tertia of 40 mesh sieves.
The degree of grinding of sye middlings, ensure that mould fungi microorganism can make full use of the starch in powdery, grows healthy and strong plentiful mycelia.Meanwhile, there is curved billet and can keep the good strength of calligraphic strokes and sedimentation due to sheet wheat skin, divides for aerobic microbiological provides sufficient oxygen in the interpolation growth of earlier fermentation amount reproduction and mycelia.Also for the abundant discharge of fermentation later stage moisture provides " passage ".
2, spice moisture is large, steps on the curved billet water content 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 increase the water content of curved billet, avoid curved billet because of moisture loss fast, cause moisture deficit, thus affect 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 is entered the room after fermentation, within first 2 days, is sprayed at equably in curved billet with bent mother liquor activate, every day 2-3 time, with keep curved billet surface humidity and for curved billet surface seeding, form good extension clothing.From curved billet enters room until in very the phase terminates, every day, water-sprinkling 3-4 time earthward, kept the humidity on ground at any time, to maintain the high humidity state of fermenting house, allow microorganism breed metabolism fully in curved billet, produce more heat energy, promote curved billet temperature to improve further, reach higher top temperature.Extend in curved billet fermentation simultaneously and endure the time, tamed the beneficial microorganism in song better.The operational path of sye middlings, large moisture, fundamentally solve posture bent ubiquitous extension clothing poor, heat up not high, in very time short, knee-piece harden do not steep gas, the difficult problem such as not thorough of fermenting.
4, curved billet earlier fermentation, utilizes water-sprinkling earthward, curved billet is sprayed bent mother liquor, start the measures such as electrothermal heating line (when room temperature is below 10 DEG C), improve temperature, the humidity in fermenting house, allow microbial spore under suitable temperature and humidity condition, promptly germinating growth.General in 24h, visible curved billet starts produce needle-like white point, after 48h, complete the extension clothing process of curved billet.In this stage, diligent door window ventilates and changes oxygen, and control temperature slowly rises, and is advisable to be no more than 40 DEG C.After 6 days, product temperature reaches top temperature 60 DEG C (with middle level curved billet thermometer), and enter the thermophilic fermentation phase, curved billet gives out strong fragrance, and therefore, this stage is also referred to as the high temperature raw fragrant phase.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, moisturizing of often spraying water earthward.
Pliotherm period hold time as 10-12 days, from earlier fermentation to subordinate phase, the temperature of curved billet is always in upward status, and range of temperature is larger, and the breeding of various microorganism is shifting, kind and the quantity of enzyme are on the increase, the compounds such as the starch in curved billet, protein, fat under the effect of various microbial enzyme, under higher temperature, humidity condition, through the chemical reaction of series of complex, the aromatics that final generation is a large amount of, forms compound Qu Xiang.This series of chemical reaction, in certain temperature range, temperature is higher, and humidity is larger, and reaction is more tending towards fierce and complicated, and the kind generating aromatics is also more.The hot and humid time length is longer, and the growing amount of aromatics is larger.Multiple a large amount of flavour ingredient and precursor, define the fragrant ability of life that Daqu strong lasting compound song is fragrant and Daqu is stronger in wine brewing process.After knee-piece fermenting-ripening, 3-6 month ability be stored and use, the quality of storage, the style that directly impact is bent and quality.
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 amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
