A kind of preparation method rich in butanedioic acid mature vinegar and the mature vinegar rich in butanedioic acid
Technical field
The invention belongs to technical field of seasoning processing, specially a kind of preparation method rich in butanedioic acid mature vinegar and it is rich in
The mature vinegar of butanedioic acid.
Background technology
The fermentation process of Shanxi mature vinegar includes two important steps of alcoholic fermentation and acetic fermentation, different in each link
Microorganism forms multi microorganism fermentation system, and mutual cometabolism, which produces to be rich in, has esters, amino acid, organic acid, vitamin etc. small
Molecular substance.These material compositions also constitute the material base of color, body, also allow vinegar to become the diet five tastes
The primary flavouring of condiment.Although acid content is very high in Shanxi mature vinegar, have no excitement, and tart flavour is soft, have acid,
The peculiar flavours such as silk floss, sweet tea, the effect of organic acid is particularly important among these, and organic acid is both again aromatic in acid substance, therefore is had
The composition and content of machine acid not only determine the peculiar flavour of Shanxi mature vinegar, and closely related with the quality of product.
Butanedioic acid, i.e. succinic acid, the fixed acid belonged in vinegar organic acid, by increasing capacitance it is possible to increase the mellow sense of vinegar, play
Coordinate vinegar flavor and improve the effect of mouthfeel, the secretion of human consumption's gland can also be stimulated, improved a poor appetite.
Corynebacterium glutamicum is a kind of facultative anaerobic microorganism, and under anaerobic, corynebacterium glutamicum does not give birth to
It is long, but the acidity of vinegar using transforming glucose as materials such as lactic acid, succinic acid and acetic acid, can be improved.In addition, glutamic acid rod-like stem
Bacterium biotransformation method produces succinic acid, mainly by the reduction branch road of krebs cycle pathway (TCA), by glycolytic pathway
(EMP) PEP or pyruvic acid obtained in passes through a step CO2Fixed and two step reduction reactions generation fourth two
Acid, therefore the targeting addition glutamic acid producer preparation in alcoholic fermentation process, promote microbial metabolism to produce butanedioic acid, utilize simultaneously
It is easy to the Zymolysis Equipment automatically controlled, so as to realize the industrialization of the vinegar brewing technique rich in butanedioic acid, standardization.
The content of the invention
The present invention is in order to solve the problem of succinic acid content is low in current spontaneous fermentation vinegar, vinegar quality difference, there is provided
A kind of preparation method rich in butanedioic acid mature vinegar and the mature vinegar rich in butanedioic acid.
The present invention adopts the following technical scheme that realization:A kind of preparation method rich in butanedioic acid mature vinegar, using sorghum as
Staple food grain, it is 1 by staple food grain, Daqu and water:0.6:2 parts are divided into after 3.3 part by weight mixing, a directly progress alcoholic fermentation
And acetic fermentation, unstrained spirits is then smoked, the Corynebacterium glutamicum bacteria preparation that distiller's wort weight 4%-7% is added in another carries out alcohol
Fermentation, then according to distiller's wort:Wheat bran:Cavings:Rice husk:The weight ratio of water is 400:120:80:80:180 mixed materials, carry out vinegar
Acid fermentation, obtain white unstrained spirits;White unstrained spirits is 7 according to weight ratio with smoked unstrained spirits:3 mixing, method is drenched by the white unstrained spirits of acquisition using circulating sleeve and smoked
Unstrained spirits carries out leaching system, the sterilizing of new vinegar, the filtering of acquisition.
Specifically comprise the following steps:
(1)Feedstock treating:Sorghum removal of impurities, as staple food grain is crushed to after 10-20 mesh under steam pressure 0.3MPa after expanding treatment,
It is standby for 10-20 mesh that Daqu is crushed to curved surface fineness;
(2)Batch mixing:Staple food grain, Daqu and water after will be expanded press 1:0.6:Compound, is then averaged by 3.3 part by weight batch mixing
It is divided into 2 parts, 1 part carries out white unstrained spirits fermentation, and 1 part carries out smoked unstrained spirits fermentation;
(3)White unstrained spirits fermentation:A, alcoholic fermentation:Corynebacterium glutamicum bacteria preparation is proportionally added into the material mixed and carries out alcohol hair
Ferment, it is 28-30 DEG C to control fermentation temperature, after 48-72h main fermentation terminate, be then sent into and support wine with dregs tank and carry out anaerobism after-ripening, control
15-20 DEG C of temperature, time 15d, complete alcoholic fermentation;B, acetic fermentation:Steam in clear soup 15 min after wheat bran, rice husk, cavings are mixed thoroughly,
25-30 DEG C is cooled to, admixes distiller's wort, intelligent continuous rotary barrel type solid-state fermentation equipment is sent into and carries out acetic fermentation, it is aqueous to mix unstrained spirits
Amount 63 ± 1%, alcoholic strength 5.5%, the interior material weight 10%-15% of inoculation fermentation equipment unstrained spirits, ferment 9-10d, obtains vinegar fermented grain;By maturation
Vinegar fermented grain compacting after it is closed, anaerobism store 7 days, control 15-24 DEG C of temperature, then enter Bai Linchi;
(4)Smoked unstrained spirits fermentation:Smoked unstrained spirits fermentation with compound be sent into intelligent continuous rotary barrel type solid-state fermentation equipment carry out alcoholic fermentation,
Acetic fermentation, fermentation condition is identical with white unstrained spirits fermentation condition, and the ripe vinegar fermented grain obtained after the completion of fermentation enters smoking unit, smokes
It is sent into smoke after 5 days and drenches pond, 85 ± 5 DEG C of control unstrained spirits temperature, once, stirring condition is inverted after being rotating forward stirring 10min and stirred for stirring daily
Mix 10min;
(5)Drench vinegar:White unstrained spirits, the smoked unstrained spirits obtained carries out leaching system using circulating sleeve leaching method, by obtained new vinegar is sterilized, filtering i.e.
Can.
The Chen Qu times of the Daqu are more than 6 months, and saccharifying power is 800 enzyme activity.
The Corynebacterium glutamicum bacteria preparation be Corynebacterium glutamicum (Corynebacterium glutamicum) hair
Zymotic fluid, the preparation method of Corynebacterium glutamicum bacteria preparation are:(1)Activated spawn:The Corynebacterium glutamicum of Storage in refrigerator is rule
It is inoculated on slant activation culture medium, 28-30 DEG C of activation 24h, the proportioning of activation medium is as follows:Beef infusion broth 1.0L, albumen
Peptone 10.0g, NaCl 5.0g, 20.0~25.0g of agar, add water to be settled to 1L, pH 7.2~7.4;The preparation of the beef infusion broth
Method is:Lean beef is cleaned, and chopping, the lean beef for weighing 550 grams of choppings is soaked in 1375ml water, soaked overnight, is filtered, filter
0.6kg/cm after liquid packing2It is standby after sterilizing 40min;(2)Switching strain:The strain activated is inoculated in BM fluid nutrient mediums
In, 30-32 DEG C of 100r/min shaking table culture 24 hours;(3) ferment Corynebacterium glutamicum bacteria preparation:By the strain of switching by inoculation
Measure in the fermentation tank equipped with fermentation medium for being transferred to and having sterilized for 10%-15%, 200r/min shaker fermentations at 30-32 DEG C
24-36 hours, the proportioning of fermentation medium are as follows:KH2PO4 0.5g,K2HPO4 0.5g,MgSO4·7H2O 0.5g,FeSO4·
7H2O 0.0006g,MnSO4·H2O 0.0042g, biotin 0.0002g and thiamine 0.0002g, add water to be settled to 1L, pH
7.0-7.2.Treat that Corynebacterium glutamicum grows to its logarithmic phase, reach 108-109Individual/ml can be used.
Corynebacterium glutamicum of the present invention (Corynebacterium glutamicum) micro- purchased from Chinese industrial
Biological inoculum preservation administrative center, numbering are:CICC 10186.
Beneficial effects of the present invention are:On the basis of traditional vinegar technology of alcohol, Corynebacterium glutamicum bacterium is added
