Problems solved by technology

Due to the differences in individual feelings and the inaccurate judgment results of this method, the quality of the sealing mud of some teams is still good after seven rounds, but they cannot accurately judge its quality and discard it, resulting in waste of resources and increased production costs
In addition, in order to strive for accuracy, technicians sometimes make frequent sensory evaluations, which consumes manpower

Embodiment 1

[0047] First, the quality-related parameters of multiple groups of sealing mud samples were measured using the above-mentioned measurement method provided by the embodiment of the present invention, including the density, maximum water content, organic matter content, porosity, and percentage of odorous substances of the sealing mud samples. The results of the measurement are shown in Table 1 below.

[0051]

[0052] The grading in Table 1 here is based on the sensory evaluation of the sealing mud samples and previous practical experience. In order to ensure that the sensory evaluation of cellar sealing mud samples is sufficiently accurate, different from the usual sensory evaluation of cellar sealing mud samples, this time each group of cellar sealing mud samples is evaluated by technicians in multiple shifts (for exa...

Embodiment 2

[0070] In the present embodiment, the organic content X of the sealing mud of a certain round of wine is measured 1 0.0342g / g, density X 2 2.47 g / cm 3 , the maximum water content X 3 31.52%, porosity X 4 is 38.85, the percentage of different smell substances X 5 It is 12.87%, according to the formula Y=K·X+b=3.124+23.573 X 1 -2.207X 2 +3.800X 3 +0.033X 4 +1.578X 5 . The result is 1.2, that is, the grade of sealing mud is about 1, and the effect is good.

Embodiment 3

[0072] In the present embodiment, the organic content X of the sealing mud of a certain round of wine is measured 1 0.0466g / g, density X 2 2.41g / cm 3 , the maximum water content X 3 31.81%, porosity X 4 is 38.95, the percentage of different smell substances X 5 It is 39.78%, according to the formula Y=K·X+b=3.124+23.573 X1 -2.207X 2 +3.800X 3 +0.033X 4 +1.578X 5 . The result is 2.0, that is, the grade of sealing mud is about 2, and the effect is better.

Abstract

The invention discloses a quality identification method for pit sealing mud, and belongs to the technical field of wine making. The method is characterized by comprising the following steps: measuring quality related parameters of a pit sealing mud sample, selecting a quality related index X from the quality related parameters, wherein the quality related parameters of the pit sealing mud sample comprises a first weight m1 obtained by weighing after drying the pit sealing mud sample at 105 to 130 DEG C and a second weight m2 obtained by weighing after drying again the pit sealing mud sample at 350 to 1000 DEG C for 1 to 3 hours, and the organic content X1 of the pit sealing mud sample is obtained from the formula in the specification; establishing function relationship between quality level scores Y and the quality related index X of the pit sealing mud sample; determining the quality level score of the pit sealing mud to be identified according to the function relationship and the quality related index of the pit sealing mud to be identified. By using the quality identification method, the quality of the pit sealing mud can be scientifically and accurately identified, and the quality identification method has a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of brewing, in particular to a method for identifying the quality of pit sealing mud. Background technique [0002] The fermentation in the cellar is one of the important features of Maotai-flavor liquor brewing, and the cellar for fermentation in the cellar is sealed with mud. Specifically, the fermenting of wine grains in the cellar is to put the accumulated and fermented wine grains into the cellar pool, and cover the surface of the cellar with a layer of about 7cm thick cellar sealing mud for sealing and fermentation. Therefore, the sealing mud plays an important role in the sealing of the cellar pool and the brewing of wine. In practice, due to the repeated use of the sealing mud, the density of the sealing mud decreases, the organic matter content, maximum water content and porosity increase, and the volatilization The increase in the content of destructive substances will lead to a decrease in the vi...
