Embodiment 1

[0026] Two-step acetic acid fermentation method produces the method for vinegar, comprises the following steps:

[0027] (1) Liquefaction of raw materials: Mix sorghum flour, corn flour and rice flour in a mass ratio of 3:2:1 as raw materials, then mix the raw materials and water evenly in a mass ratio of 1:3.5, and then add 0.3% of the total weight of raw materials High-temperature amylase, liquefied at 98°C for 1 hour;

[0028] (2) Alcoholic fermentation: after the liquefaction is completed, when the temperature drops to 30°C, add 30% Daqu, 20% saccharified koji, 10% red koji, 0.1% Saccharomyces cerevisiae and 0.05% aroma Yeast, after stirring evenly, carry out low-temperature continuous aeration or open-open fermentation for the first 24 hours. The temperature is kept at 29°C. After 24 hours, carry out airtight anaerobic fermentation. The fermentation period is 5 days. ;

Abstract

The invention discloses a method for producing table vinegar by adopting a two-step acetic acid fermentation method and belongs to the technical field of brewing of the table vinegar. According to the method, the problems of low alcohol intolerance, long fermentation period and low acetification rate for acetic acid fermentation in a traditional method are solved. The method comprises the following steps of: uniformly stirring sorghum flour, corn flour, rice meal and water; adding thermostable alpha amylase for liquefying; after liquefying, reducing the temperature, adding Daqu, saccharifyingkoji, red starter, saccharomyces cerevisiae and aroma-producing yeast and carrying out alcoholic fermentation to obtain liquor; adopting the two-step acetic acid fermentation method: firstly, mixing the liquor; adding acetic acid bacteria subjected to liquid amplification culture for carrying out primary acetic acid fermentation; when the alcoholic strength of brewing mass is reduced to 6-5DEG C,adding wheat bran and rice husk as accessories for mixing; inoculating fire fermented liquor for carrying out secondary acetic acid fermentation; sealing the liquor; smoking the liquor; spraying vinegar; filtering; and packaging to obtain a finished product. According to the method disclosed by the invention, the high-content alcohol can be effectively converted; the acid yield and the acetification rate in unit time are improved; and the flavor of the table vinegar produced by adopting a traditional solid acetic acid fermentation method is ensured.

Description

technical field [0001] The invention belongs to the technical field of vinegar brewing, and relates to a method for producing vinegar by two-step acetic acid fermentation. Background technique [0002] According to reports, the annual output of vinegar in the world is as much as 20 million tons, and the annual output of vinegar in my country is about 3.5 million tons, of which the grain vinegar made from grain is the main one. In the traditional brewing method, solid-state fermentation uses grain as the main raw material, which is crushed, stirred with water, steamed, and fermented with alcohol. If rice is used as the main ingredient, it should be cooked and cooled to about 30°C, then mixed with rhizopus wine medicinal starter, and then mixed with rice bran and acetic acid bacteria seeds (fired unstrained spirits) after brewing wine to carry out acetic fermentation. Continue to turn the unstrained spirits in the cycle to mature. [0003] Solid-state acetic acid fermentation...
