Embodiment 1

[0040] (1) Screen and weigh each formula component as required

[0041] Prepare mixed mud 1000kg (including loess 600kg, lotus pond mud 300kg, old cellar mud 100kg

[0042] On this basis, add the following substances in proportion:

[0043]

[0044] (2) Prepare high-quality artificial pit mud according to the aforementioned preparation steps.

[0045] (3) Natural fermentation culture of artificial pit mud

[0046] The artificial pit mud starts to ferment the next day, observe the fermentation situation, and make a record of the temperature of the fermentation tank. The temperature of the cellar pool is controlled at 30-35°C.

[0047] (2) The fermentation time is 50 days. The high-quality artificial pit mud tested after fermentation is taken out and put into production.

Embodiment 2

[0049] Use the fermented pit mud to build a pit in the koji wine workshop. After removing the bad grains from the cellar pool, clean the four walls, and paste the mature pit mud with a thickness of 15-20cm from the bottom, 15cm from the bottom, and 8cm from the top. Go up, and then produce raw wine on the basis of the original production process. The fermentation period is 60 days. The inspection results of the high-quality raw wine produced are as follows:

[0050] Table 1 The quality of liquor after using artificial high-quality pit mud

[0051]

[0052] It can be seen from Table 1 that after the use of artificial high-quality pit mud, the quality of the produced liquor remains stable after round rowing, and the concentration of ethyl hexanoate reaches 3.0g / above, which meets the standard of high-quality liquor and achieves the expected purpose.

Abstract

The invention provides high-quality artificial pit mud in Baijiu production and a preparation method of the high-quality artificial pit mud in the Baijiu production. The high-quality artificial pit mud comprises the components of loess, lotus pond mud, aged pit mud, peat, yeast powder, silkworm chrysalis powder, bone meal, caproic acid bacteria solutions, dipotassium phosphate, sodium acetate, magnesium sulfate, ammonium sulfate, soybean cake powder, yellow water, after-run, pot bottom water and the like. The preparation method comprises the following steps: 1) selecting raw materials according to requirements, and weighing each component according to the proportion; 2) preparing the high-quality artificial pit mud, namely mixing and stirring uniformly according to the dry-to-wet order, controlling the water content within 40 to 45% by pot bottom water, adjusting the pH value within 6.0 to 6.8, beating the mud into a pit, covering the pit mud tightly by plastic cloth, and tucking four sides tightly; 3)carrying out natural fermentation cultivation on the artificial pit mud, controlling the pit entering temperature at 30 to 35 DEG C, and lasting the fermentation time for 30 to 60 days; testing to reach standards, thus obtaining the high-quality artificial pit mud. The high-quality artificial pit mud disclosed by the invention is simple in preparation, short in fermentation and aging time and good in effect, can be used for replacing the high-quality aged pit mud and put into production, and further has very good economic benefits and social benefits.

Description

technical field [0001] The invention relates to a technique for liquor production, in particular to a high-quality artificial pit mud for liquor production and a preparation method thereof. Background technique [0002] We know that in the production of Luzhou-flavor liquor, pit mud is the foundation, craftsmanship is the key, koji medicine is the driving force, and blending is the guarantee. There are a large number of beneficial microorganisms mainly caproic acid bacteria in the pit mud. They use the pit mud as their habitat, and the fragrant grains as their source of nutrition. After a long period of infiltration in the mud grains, these beneficial bacteria grow, reproduce, metabolize, and interact with each other The coordination effect has created the unique aroma and style of Luzhou-flavor liquor with ethyl caproate as the main aroma. Therefore, high-quality pit mud is the basic condition for producing high-quality Luzhou-flavor Daqu liquor. However, the pit mud of ...
