preparation example Construction

[0024] A preparation method of selenium-enriched pit mud, comprising the following steps:

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

[0026] S2. Add 20% of the old pit mud (cellar age more than 10 years) to the primary cellar mud and mix evenly, apply to the wall of the new cellar pool (cellar age less than 3 years), the thickness is 4-8 cm, and the bottom of the pool is 10-20 cm. The koji powder with 1% mass of the pit mud is added to the fermented grains, fermented by the conventional process, and after 2-3 normal fermentations, the selenium-enriched pit mud i...

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 ...
