Description

Acetic acid fermentation process for mature vinegar by steaming auxiliary materials and vinegar residues
Technical Field
The invention relates to the technical field of mature vinegar production, in particular to an acetic acid fermentation process of mature vinegar with steaming auxiliary materials and vinegar residues.
Background
The traditional brewing technology of Shanxi mature vinegar is a national non-material cultural heritage, which is prepared by taking sorghum as a main raw material, taking bran, chaff and rice husk as auxiliary materials, taking Daqu prepared from barley and peas as raw materials as a saccharification starter, fermenting by adopting solid acetic acid after alcohol fermentation, and brewing by processes of fumigating, ageing and the like, wherein the product has unique flavor of 'sour, soft, sweet, fragrant and fresh'.
The main function of the auxiliary materials such as bran, chaff, rice husk and the like is to loosen vinegar grains of acetic acid fermentation, absorb moisture, store air, adjust the moisture content and the alcohol content before fermentation, and facilitate the smooth fermentation. However, these auxiliary materials are the outer shell parts of fruits where crops are directly exposed, often have the offensive smell, the evil foreign taste and the bran foreign taste, and are the main sources of the unpleasant taste in the vinegar. And the auxiliary material bran contains a certain amount of nutrient substances, and is extremely easy to be damp and mildewed and insect-grown in the storage process.
The Shanxi province is a Shanxi province for producing vinegar, a large amount of vinegar residues are produced when the Shanxi mature vinegar is brewed by the traditional process, and if the vinegar residues are not timely and effectively utilized, the problems of environmental pollution, soil acidification and the like can be caused, and the vinegar residues are concentrated in feed, fertilizer, matrix and energy utilization. However, the vinegar residue has loose structure and good air permeability, and also contains partial nutrient substances, can be used as a culture medium for acetic acid bacteria growth, is acidic, and can make the new fermented grains slightly acidic after being mixed with the wine mash and auxiliary materials, can inhibit the propagation of miscellaneous bacteria, and can be completely used as auxiliary materials to be added in the acetic acid fermentation process of brewing vinegar to replace partial chaff and rice husk in the traditional acetic acid fermentation material mixing process of brewing mature vinegar.
At present, the auxiliary material steaming process introduced in Chinese patent CN200510020564.2 ' a process for brewing strong aromatic white spirit ' by first clearing and bottom reaching ', which is used for screening auxiliary materials namely chaff steaming to ensure the porosity of fermented grains, but the patent does not innovate a steaming mode method, and the brewing and steaming auxiliary material process is used for steaming auxiliary materials while steaming the auxiliary materials and can not be used for singly mechanically steaming the auxiliary materials in the brewing process of mature vinegar due to the difference of the processes; chinese patent CN201810001094.2, "an anti-oxidation factor-enriched mature vinegar and preparation method thereof," only refers to steaming auxiliary materials, and is not described in detail. In addition, the technology for recycling the vinegar residue after treatment in the brewing process of the mature vinegar is not disclosed yet, the prior art has the technology that the vinegar residue is directly mixed with bran koji and added into the acetic acid fermentation and mixing process of the Shanxi mature vinegar, and the vinegar residue enters the acetic acid fermentation process after stacking, and the technology can utilize part of the vinegar residue, but the using amount of the vinegar residue is far smaller than the generating amount of the vinegar residue, the utilization rate of the vinegar residue in the brewing process of the edible vinegar is lower, most of the vinegar residue still adopts forage and fertilizer treatment, and the waste of resources is still caused for edible vinegar production enterprises, so the method for recycling the vinegar residue needs intensive research.

(1) And (3) vinegar residue extrusion: vacuum squeezing and filtering the fresh wet vinegar residue to obtain dehydrated vinegar residue;
(2) Steaming auxiliary materials and vinegar residue: the method comprises the steps that a horizontal continuous auxiliary material steaming machine is adopted to steam auxiliary materials and dehydrated vinegar residues, a shell of the horizontal continuous auxiliary material steaming machine is made of an aluminum plate or a stainless steel plate, materials are conveyed through a stainless steel mesh belt, steam penetrates through a material layer from the bottom, the whole machine body conveying process is closed, the horizontal continuous auxiliary material steaming machine is provided with three feed inlets which are an auxiliary material bran feed inlet, an auxiliary material chaff feed inlet and a dehydrated vinegar residue feed inlet respectively, the auxiliary materials and the dehydrated vinegar residues enter the mesh belt from the respective feed inlets, the thickness of the materials is controlled to be 20-40cm by a material adjusting plate, the materials move slowly along with the mesh belt, steam in the steam chamber is sprayed out through a steam pipeline, the steam penetrates through the mesh belt to steam the materials, the travel of the materials on the whole mesh belt is required to be 20-30min, the steaming temperature is 100 ℃, the steamed materials are discharged to the conveying belt at the tail end of the auxiliary material steaming machine under normal pressure;
(3) Mixing materials to prepare fermented grains: conveying the steamed vinegar residue and auxiliary materials to a mixing stirrer through a conveying belt at the temperature of 40-45 ℃ by utilizing the residual heat after the auxiliary materials and the vinegar residue are steamed, uniformly stirring the materials with the wine mash after the alcoholic fermentation is finished to prepare fermented grains, and then discharging the fermented grains into an acetic acid fermentation tank or a jar through a fixed point of the conveying belt, wherein the temperature of the fermented grains is 38-40 ℃, the moisture content of the new fermented grains is 65-70%, and the alcoholic strength is 4.3-4.5%vol;
(4) And (3) fire connection: after acetic acid fermented grains are put into a pool or a jar, the fermented grains are inoculated rapidly;
(5) Acetic acid fermentation: starting acetic fermentation after the connection of fire, turning over the fermented grains every day, wherein the total acid is more than or equal to 4.5g/100mL after 10-11 days, the alcoholicity is less than 0.2 ℃, the vinegar grains are copper brown and glossy, the acetic fermentation is finished when the vinegar flavor is present, the acetic fermentation is finished, and the steps of fumigating the grains and spraying vinegar are performed.
The vinegar residue and the auxiliary materials are treated by the high Wen Qingzheng, so that the effects of sterilizing and killing eggs can be achieved, and a high safety defense line is built for vinegar production; meanwhile, the vinegar residue and auxiliary materials have the pathogenic odor, the earthy odor, the vinasse odor and the bran odor, and also contain some polyglutamate, so that aldehyde substances such as furfural and the like are generated in the fermentation process, and the vinegar is burnt and bitter, and if the vinegar is not specially treated, the brewed vinegar may have the pathogenic odor, the bran odor, the burnt bitter and other bad odors. The bad smell in the vinegar residue and auxiliary materials can be removed by steaming before acetic acid fermentation, so that the taste of the brewed vinegar is purer.
Preferably, in the above-mentioned acetic acid fermentation process of the aged vinegar containing steaming auxiliary material and vinegar residue, the moisture content of the dehydrated vinegar residue is 40-45%.
The beneficial effects of the technical scheme are as follows: the material after the fermentation is finished is called new fermentation, the water content of the traditional brewing process is about 62-70%, the water content of the traditional brewing process is a key control point of an acetic acid fermentation stage, the water content of the traditional brewing process after the fermentation is derived from two parts, the main source is the water content in the mature beer mash, and the water content of the raw and auxiliary materials, namely bran, chaff and rice husk, is generally lower than 20%. However, the moisture content of the wet vinegar residue is generally 65-72%, which is far higher than that of the auxiliary materials such as bran, chaff and rice husk, if the vinegar residue is taken as the auxiliary material to be added into the acetic acid fermentation process in a large amount, the moisture content of the new fermented grains is increased, the mixed bacteria are easily polluted by the fermented grains with the excessive moisture content, and the microorganisms in the fermented grains are excessively fast to metabolize, so that the raw materials are not thoroughly utilized. The water content of the vinegar residue is reduced to 40-45% after the vinegar residue is extruded and filtered, and the dehydrated vinegar residue amount which can be used for acetic acid fermentation is obviously increased under the influence of 62-70% of the water content of the new fermented grains.

Preferably, in the above-mentioned acetic acid fermentation process for steaming auxiliary materials and vinegar residues, the inoculation amount of the fire fermented grains in the step (4) is 10-15% of the amount of the acetic acid fermented grains.
The beneficial effects of the technical scheme are as follows: the acetic acid bacteria are main strains in the acetic acid fermentation process, the inoculation amount of the fire grains is consistent with that of the traditional brewing process, the dominant strains in the new grains are yeasts, only a small amount of acetic acid bacteria are contained, and the acetic acid bacteria cannot be made into dominant strains in the new grains in a short time, so that a large amount of acetic acid bacteria (fire grains) in a growth log phase are required to be inoculated, so that the acetic acid bacteria are greatly propagated in the new grains and quickly become dominant strains, and acetic acid fermentation is carried out. The main reason that acetic acid bacteria are required to be fast changed into dominant bacteria is that the quality of finished vinegar is affected due to the fear of pollution of mixed bacteria, and the inoculation amount of fire grains is set to be 10-15% from the aspects of portability of operation, yield of vinegar, enterprise cost and the like.
Preferably, in the above-mentioned process for fermenting mature vinegar with steaming adjuvant and vinegar residue, in the step (5) acetic acid fermentation, the temperature is controlled at 38-40deg.C for 3 days before fermentation, 45-48deg.C for 4-8 days, and 35-38deg.C for 9-11 days.
The beneficial effects of the technical scheme are as follows: the temperature is controlled to be 38-40 3 days before fermentation, the temperature is fast, bacteria are not easy to dye, the pre-heating period can be shortened, beneficial microorganisms are rapidly developed into dominant strains, the temperature is controlled to be 45-48 ℃ 4-8 days after fermentation, acetic acid bacteria are well metabolized, lactic acid bacteria, monascus, aspergillus flavus and other high-temperature strains are well metabolized, and rich pyrazine, phenols and other components are produced by the metabolism of the high-temperature strains, so that the aroma contribution to the finished vinegar is large. The temperature of fermentation is controlled to be 35-38 ℃ in 9-11 days, which is favorable for the continuous conversion of residual starch, sugar and ethanol and improves the yield.
Compared with the prior art, the invention discloses an acetic acid fermentation process for steaming auxiliary materials and vinegar residues, which has the following advantages:
(1) According to the invention, the vinegar residue produced by the traditional mature vinegar brewing process is extruded and filtered, the water content of the vinegar residue is reduced, the use ratio of the vinegar residue is more than 26%, and the use ratio of the vinegar residue in the research on the vinegar residue continuous [ Mi Cheng ] live acetic acid fermentation mature vinegar production process is about 8.2-10.3%, compared with the vinegar residue, the use ratio of the vinegar residue in the process is greatly improved, and the problems of difficult utilization of the vinegar residue and resource waste are solved;
(2) The temperature of the fermented grains is about 20-25 ℃ when the traditional Shanxi mature vinegar process is not connected with fire, the temperature of the connected fire fermented grains is about 40-43 ℃, and the temperature of the connected fire fermented grains is low, so that the growth of acetic acid bacteria is not facilitated, and the fire starting (the acetic acid bacteria widely grow in a whole pond or a jar, the temperature of the fermented grains in the whole pond or the jar is about 40 ℃, and acetic acid fermentation starts to enter a vigorous stage) needs 1-2 days. The process utilizes the waste heat after steaming auxiliary materials and vinegar residues, and mixes the steamed auxiliary materials, vinegar residues, wine mash and fire grains, wherein the temperature is about 38-40 ℃, acetic acid bacteria in the fire grains are beneficial to quickly oxidizing alcohol into acetic acid at the temperature, and the propagation of the acetic acid bacteria is completed when the ethanol is oxidized, so that the fire is rapid, and the acetic acid fermentation period is obviously shortened by 1-2 days;
(3) In the traditional brewing process of the mature vinegar, the auxiliary materials for acetic acid fermentation are used as the auxiliary materials and the filling materials for acetic acid fermentation, wherein the auxiliary materials comprise 80-120% of chaff and 30-50% of rice husk, which are used as raw materials, by weight of sorghum. The process disclosed by the invention uses wet vinegar residues generated in the traditional Shanxi mature vinegar brewing process, and completely replaces rice hulls in the traditional Shanxi mature vinegar brewing acetic acid fermentation process after extrusion, filtration and steaming, so that rice hulls are replaced by nearly 50%, and the production cost of enterprises is reduced. The bran contains a large amount of fermentable starch and a proper amount of protein, has loose texture, light weight and large surface area, can contain certain air, and is an indispensable auxiliary material in the acetic acid fermentation process; the chaff has better porosity and water absorption; although the rice hulls are good in porosity, the rice hulls are poor in water absorption, and the effects of the rice hulls on adjusting some physicochemical indexes of the new fermented grains such as indexes of starch, moisture, sugar degree, alcohol degree and the like are poor compared with the rice hulls; the vinegar residue has loose structure and good air permeability, and also contains partial nutrient substances, and can be used as auxiliary materials and filling materials for acetic acid fermentation. Therefore, the invention completely replaces rice hulls with steamed vinegar residues and replaces partial rice hulls, thereby greatly reducing the production cost of enterprises.
