Example Embodiment

[0024] A method for preparing selenium-rich pit mud includes the following steps:

[0025] S1. Take selenium-enriched clay, distiller’s grains, bean cake, potassium dihydrogen phosphate, and koji powder in proportion, stir it evenly, add yellow water and tail water to mix evenly, make the pit mud water content 45-55%, stack it, cover the straw, Fermentation at 25-35°C for 60 days, during which the surface of the pit mud is sprinkled and cured to keep the surface moist, and the primary pit mud is obtained.

[0026] S2, the primary pit mud is mixed with 20% old pit mud (the pit age is more than 10 years), smear it on the wall of the new pit pool (the pit age is less than 3 years), the thickness is 4-8 cm, and the bottom is 10-20 cm. Koji powder with 1% of the quality of the upper pit mud is added to the fermented glutinous rice and fermented by conventional technology. After 2-3 times of normal fermentation, the selenium-rich pit mud is obtained.

[0027] S3. When making selenium-enri...

Abstract

The invention provides selenium-rich pit mud. The selenium-rich pit mud is prepared from selenium-rich clay, vinasse, soybean cakes, potassium dihydrogen phosphate, yellow water, tail water and yeastpowder, wherein mass parts of vinasse, soybean cakes, potassium dihydrogen phosphate, yellow water, tail water and yeast powder account for the mass of selenium-rich clay by 2-3%, 2-3%, 0.5-1.5%, 1-5%, 1.5-2.5% and 1-2% respectively. The selenium-rich pit mud and the preparation method thereof by adoption of selenium-rich soil for preparation of the pit mud, inorganic selenium in the soil is converted into organic selenium by microorganisms such as selenium-rich yeast in a pit-sealed fermentation process; by natural enrichment of mineral elements such as selenium, the selenium content of fermented wine is increased, and generation and accumulation of aroma and flavor substances in a fermentation system are promoted.

Description

technical field [0001] The invention relates to the technical field of selenium-enriched liquor brewing, in particular to a selenium-enriched cellar mud and a preparation method thereof. Background technique [0002] To produce selenium-enriched liquor, pit mud is the basis. Pit mud is the clay used to seal the pit and make the bottom of the pit, that is, the sealing equipment for the anaerobic fermentation of the fermented grains in the pit. The quality of the pit mud directly determines the quality of the wine. inferior. Pit mud is also the carrier of microorganisms. Pit mud is the carrier and habitat of various beneficial microorganisms such as caproic acid bacteria, methane bacteria, and butyric acid bacteria, and is also a hotbed for their reproduction. The types and quantities of these beneficial microorganisms are the measure of pit mud. of a standard. The cellar pool is built with artificial pit mud, and after a long period of training, an artificial old cellar is ...
