Embodiment 1

[0022] 1. The preparation process of lactic acid bacteria culture solution is:

[0023] (1). Strain activation: connect the preserved original species Lactobacillus delbrueckii to 10ml5 0 In the test tube medium of Bx wort, culture at 45°C for 24h. It can be transferred several times appropriately.

[0024] (2). First-level seed culture: Put the above-mentioned test tube culture solution into a triangular flask containing 200ml culture solution. The composition of the culture medium is: wort 6~8 0 Bx, yeast extract 1g / L, natural pH. Sterilize for 20-25 minutes at a gauge pressure of 90kPa. After inoculation, incubate at 48-50°C for 12 hours, the pH drops to 3.5, add a small amount of sterilized calcium carbonate, and continue to incubate for 10-12 hours.

[0025] (3) Preparation of sugar solution and yeast mud: take the saccharification solution in production, and then measure a small amount of yeast mud in the alcohol fermentation mash that has been fermented for 72 hours, add it...

Embodiment 2

[0039] After pulverizing the main raw material Yuan rice and sorghum rice into powder, add water to make a powder slurry and add 5-10U / g raw material starch amount of high-temperature α-amylase, heat up to 85℃~92℃, liquefy for 10~15min, then heat up Inactivate the enzyme at 100°C for 5 minutes, then cool down to 65°C, pour it into the glucoamylase tank, and add 6-8U / g raw starch glucoamylase. After saccharification at 63°C for 1.5h, cool down to 30°C and add 10% Daqu and 0.15% Saccharomy cerevisiae (Saccharomy cerevisiae) were expanded by alcohol fermentation at 33°C for 64 hours to obtain a mash with 8% (v / v) alcohol concentration. Put the wine mash into the acetic acid fermentation tank, and add the auxiliary materials wheat bran, sorghum and 1% cultured mature acetic acid bacteria (AS.1.01) solution according to the ratio of main ingredients and auxiliary ingredients of 1:3, and add 2% according to the implementation Example 1: Preparation process of lactic acid bacteria cultur...

Embodiment 3

[0041] After pulverizing the main raw material Yuan rice and sorghum rice into powder, add water and adjust into a powder slurry, high temperature α-amylase, liquefy by heating for 10-15 minutes, inactivate enzyme at 100°C for 5 minutes, cool down to 65°C, add glucoamylase After saccharification for 1.5 hours, cool down to 30°C, add 10% Daqu and 0.2% of high-temperature resistant brewing active dry yeast (Saccharomy Cerevisiae) expanded wine mother, and alcoholic fermentation at 33°C for 64h to obtain 7.5% (v / v) Alcoholic mash. Put the wine mash into the acetic acid fermentation tank, and add the auxiliary materials wheat bran, sorghum and 1% cultured mature acetic acid bacteria (AS.1.01) solution according to the ratio of main ingredients and auxiliary ingredients of 1:2.5, and add 0.5% according to the implementation Example 1: Preparation process of lactic acid bacteria culture broth. Expanded culture broth of lactic acid bacteria (Lactobacillus delbrueckii), heated and fermen...

Abstract

The invention discloses a making method of health vinegar, which is characterized by the following: adopting Chinese sorghum (rice) as raw material and bran, Chinese sorghum, rice shell (jujube,longan, safflower, liquorice, tremella, honey and so on) as auxiliary material; obtaining the health vinegar with total acid not less than 2. 5% and not less than 1. 0% non-volatile acid and reducing sugar not less than 2. 0g/100ml; displaying gloss, amber colour to reduce serum cholesterol.

Description

Technical field [0001] The present invention belongs to the field of condiment brewing engineering technology. It is an organic combination of modern biological and chemical engineering technology and traditional brewing engineering technology. It is a clarified and non-deteriorating vinegar (health vinegar) created by the improvement of the current vinegar production process. Manufacturing process. technical background [0002] With the improvement of people's awareness of life and health care, the quality requirements for vinegar and the demand for vinegar have greatly changed and increased. People are increasingly demanding green organic vinegar with unique flavor, high quality, and low health care. The specific requirements are: (1) The raw and auxiliary materials used in production are all green and organic; (2) The taste is changed from extremely sour vinegar with a total acid content of 50-100g / L to a sweet and sour with a total acid content of 35g / L. Type vinegar; (3) In ...
