Embodiment
The method that the many bacterial classifications of employing of the present invention are produced Shanxi mature vinegar is on the traditional technology basis, adopts the front end product of modern microbial technique and zymin application facet, at the improvement of Shanxi mature vinegar zymotechnique.
Method of the present invention has comprised the main technique step in original Shanxi mature vinegar production, that is:
Raw material processing → liquefaction → saccharification → wineization → acetify → smokedization → (pouring vinegar) ageing;
Method of the present invention mainly is the part link in above-mentioned technological process, adds amylase, saccharifying enzyme, wheat bran, the special-purpose Daqu of old vinegar, fixed yeast etc. stage by stage respectively; Interpolation is in proper order:
A. raw material liquefaction stage: adding content by per hundred kilograms of raw material weights is the amylase 50-70ml of 100,000 unit of enzyme, and adding temperature is 90-100 ℃.
Main purpose in this stage is that the long-chain starch in the raw material is converted into short-chain amylose, traditional technology is to adopt the way of immersion and boiling to make starch pasting, present method adds amylase after raw material is heated to 90 ℃, and amylase cuts the macromole long-chain starch in the raw material and makes it promptly be converted into micromolecular dextrin in the short period of time.
B. the saccharification stage adds: adding content by per hundred kilograms of raw material weights is the saccharifying enzyme 160-240ml of 100,000 unit of enzyme; Wheat bran 15-30Kg, adding temperature is 55-65 ℃.
Starch material is after liquefaction stage is converted into dextrin, and the effect in this stage through saccharifying enzyme will make it be converted into grape glucose.Simultaneously, in order to keep the local flavor of traditional Shanxi mature vinegar, also will add a certain amount of wheat bran, its effect is to promote saccharifying, simultaneously materials such as the protein in the raw material, pectin and hemicellulose is converted into materials such as amino acids, lipid, alcohols.Add wheat bran and also help certain assorted bacterium quantity in the maintenance feed liquid, be beneficial to the carrying out of subsequent technique and the maintenance of traditional flavor.
C. wine stage: add the special-purpose Daqu 20-30Kg of old vinegar by per hundred kilograms of raw material weights, adding temperature is 30-35 ℃; Adding cell count is the fixed yeast liquid 20-24Kg of 0.8-1.2 hundred million, and adding temperature is 25-35 ℃.
This stage is one of main fermentation stage of Shanxi mature vinegar production technique.Transforming gained glucose etc. and be converted into alcohols material and a small amount of lipid material in this stage will be with saccharifying, wherein mainly is ethanol in the alcohols material.Its main organism of fermentation is a yeast, and the present invention has adopted the fixed yeast fermentation process to make the fermented yeast bacterial classification.Described fixed yeast fermentation process is one of new technology of system wine sector application comparative maturity, but have no precedent precedent in the vinegar industry, reason is to make vinegar than wine brewing process complexity, it is more to relate to microbe species, wine can keep its traditional style by blending old vintage, but the particular flavor with old vinegar of historical tradition hardly may be by blending acquisition.Can only obtain by specific brewing process.Therefore, the making method of various traditional vinegars of China all changes not quite so far.Method of the present invention is introduced the Shanxi mature vinegar production process with the fixed yeast zymotechnique, its main processes is identical with the method for making liquor process, concrete steps comprise: the required bacterial classification of inoculation wine yeast in solid support material, adding is a certain amount of aforementioned through saccharification stage gained saccharification material after putting into yeast culture tank, and maintenance inserts the required temperature range (usually between 20-35 ℃) of bacterial classification, cultivate after 8-12 hour, promptly obtain the fixed yeast liquid that cytokine reaches 0.8-1.2 hundred million, it is added the wine jar, and adding temperature is 25-35 ℃.
The bacterial classification that inserts in present method immobilized yeast vector material mainly is liquor-making yeast and ester-producing yeast two classes.In liquor-making yeast, also can select simultaneously thermotolerant yeast and acidproof yeast as auxiliary yeast.So-called thermotolerant yeast refers to that leavening temperature is at 28-38 ℃ yeast.Add the heatproof degree that can improve whole fermented bacterium group behind this yeast-like fungi, make Shanxi mature vinegar not need season the manual shift room temperature still can ordinary production at summer high-temperature.Acidproof yeast refers to still can keep when distiller's wort acidity reaches 1-1.2 the yeast of vigorous vigor.Select for use such barms can make mash than under the low ph condition normally the fermentation.
Wine yeast commonly used has the Lars, and No. 2, No. 12, Lars, K word yeast, Nanyang No. 5 yeast, Nanyang mix 1308 yeast, workers and peasants' 501 yeast.Ester-producing yeast comprises No. 1295 yeast of AS.2300 yeast, AS2.338 yeast, the preservation of food fermentation institute of former China National Light Industrial Products Department, No. 1312 yeast, No. 1274 yeast, Hansenula anomala.Thermotolerant yeast wherein and acidproof yeast can reach 30-33 ℃ by selecting in the wine yeast as No. 12 yeast fermentation temperature in Lars, reach as high as 38 ℃, are ideal thermotolerant yeasts comparatively; It then is the acidproof yeast of using always that 1308 yeast are mixed in Nanyang.
In addition, in the wine jar, also add the special-purpose Daqu of Shanxi mature vinegar, be traditional be the special-purpose Daqu of Shanxi mature vinegar that raw material is made with barley and pea, its effect is in order to promote wine speed and to keep carrying out smoothly of traditional Shanxi mature vinegar local flavor and subsequent technique.Multiple microbial process in this special use Daqu has guaranteed the peculiar flavour of Shanxi mature vinegar.
In traditional old vinegar production technique, be that the raw material of boiling is directly mixed to go into cylinder behind the song and ferment.The saccharification of raw material and wineization are simultaneously or intersect and carry out.Therefore, its production cycle is very long, and prepared using is not thorough, and the Daqu consumption is a lot.The special-purpose Daqu consumption of old vinegar has only the 40-50% of traditional technology consumption in the technology of the present invention.And fermentation time shortens greatly.
Acetify fermentation stage subsequently and pouring vinegar are then identical with traditional Shanxi mature vinegar technology with the ageing process process.Present method has inserted thermotolerant yeast and acidproof yeast in fixed yeast liquid, therefore, unstrained spirits stage fermentation temperature can reach 42-48 ℃ in acetify, the high 5-8 of acetify temperature of more traditional Shanxi mature vinegar technology ℃, the acetify time decreased 1-3 days, the per kilogram major ingredient goes out sour rate then have been increased about 20%.Single sour cost has only 45% of traditional technology.
Each the phase temperature scope that provides in the specific embodiment of the present invention plays the temperature range of the microorganism suitable growth of principal fermentation when representing this stage, be meant the temperature range that enzyme activity is the strongest for amylase or saccharifying enzyme.Amylase and saccharifying enzyme all can be buied from the domestic market.
