Anti-deterioration cellar mud and preparation method thereof

Abstract

The invention discloses anti-deterioration cellar mud and a preparation method thereof. Based on 100 percent of yellow clay, the anti-deterioration cellar mud comprises the following components: 3 to 5 percent of yeast powder, 8 to 10 percent of double bottom dreg, 5 to 8 percent of mixed culture solution of caproic acid bacteria and liquid cellar mud, 2 to 3 percent of M type microbial fermentation liquor, 15 to 20 percent of peat, 5 to 8 percent of cellar mud, 10 to 12 percent of yellow water, 1 to 2 percent of propionibacterium liquid, 4 to 6 percent of impure alcohol, 2 to 3 percent soybean cake powder and 0.05 to 0.1 percent of K2HPO4. The cellar mud realizes the rational regulation of pH value, moisture, humus, nutrient substance, N, P, K and the like by the regulation of a formula and the ratio of the mixed culture solution of the M type microbe to the propionibacterium liquid to the caproic acid bacteria to the liquid cellar mud is well regulated, so that the pH value of the active and excellent cellar mud is always maintained between 5 and 7.

Description

technical field

[0001] The invention relates to the technical field of liquor brewing, in particular to an anti-degeneration pit mud and a preparation method thereof. Background technique

[0002] The quality of Luzhou-flavor Daqu liquor is closely related to the quality of the pit mud. The reason is that the microorganisms in the pit mud can produce chemical substances with pit aroma, strong aroma and complex aroma during the fermentation process of the fermented grains. Since the artificial pit mud has been widely promoted, various enterprises use artificial pit mud for the production of Daqu liquor, but many enterprises pay too much attention to the index of caproic acid bacteria in the cultivation of artificial pit mud and ignore caproic acid bacteria reproduction, Various conditions of metabolism, especially some microorganisms that play a coordinating role in the pit mud are neglected, so that the cultivated artificial pit mud tends to degrade after a certain period of...

[0025] The preparation method of the above-mentioned anti-degeneration pit mud comprises the following steps:

[0026] A. Finely crush the yellow clay and lay it flat on the production site, evenly sprinkle boiling water and infiltrate it for 24 hours, requiring uniform infiltration;

[0027] B. Sprinkle peat on the soaked yellow clay and dig carefully. It is required to mix the yellow clay and peat evenly, and then sprinkle the boiled yellow water, wine tail, K 2 HPO 4 After the solution is mixed evenly, cover with plastic film and infiltrate for 20 hours;

[0028] C. Uncover the plastic film, evenly spread the pit mud, bean cake powder, Daqu powder, and double-wheel bottom grains on the soil soaked with various materials, and then dig the third time to ensure that the digging is thorough and even ;

[0029] D. Put the mud mixer in place, turn on the power button, and sprinkle the mixed culture solution of caproic acid bacteria, liquid pit mud, propionic acid bacteria liqu...
