Process for producing lees-burnt baijiu by using first-stage yellow wine lees

Abstract

The invention discloses a process for producing lees-burnt baijiu by using first-stage yellow wine lees, and belongs to the technical field of wine brewing. The process comprises the following steps:carrying out direct or solid-state stacking fermentation on the yellow wine lees which are obtained by brewing, squeezing and separating according to the conventional yellow wine production process; distilling remaining lees (commonly known as the first-stage yellow wine lees) after processing of the lees-burnt baijiu; after cooling and crushing the remaining lees, uniformly inoculating multi-grain distiller's yeast and baijiu functional bacteria into the remaining lees; meanwhile, adjusting the water content; and after carrying out solid-state stacking fermentation for 5-10 days, carrying outdistilling to obtain the lees-burnt baijiu. Results show that the lees-burnt baijiu produced by the process has the yield about 8% (converted into 50% vol of alcoholic strength); compared with first-stage lees-burnt baijiu (baijiu obtained after distilling the yellow wine lees for the first time), the lees-burnt baijiu has the advantages of high total ester, low fusel oil, light after-bitterness,soft and sweet mouthfeel and the like; and the utilization rate of raw materials is improved, and moreover, the protein content in the yellow wine lees is improved by 3 to 5 percent; and if the yellow wine lees is used as a feed raw material, the selling price can also be further increased.

Description

technical field [0001] The invention discloses a process for producing distiller's distiller's distiller's grains with distiller's grains, and belongs to the technical field of brewing. Background technique [0002] Yellow distiller's grains is one of the main by-products in the brewing of yellow rice wine. Taking traditional Shaoxing Yuanhong wine or Jiafan wine brewing as an example, the final grain production rate is about 35% (calculated by feeding glutinous rice). This fresh yellow distiller's grains It contains about 10% alcohol, about 50% volatile components, about 35% crude starch, about 10% protein, about 6% crude fiber, and is rich in nutrients. [0003] The original method of large-scale rice wine enterprises to deal with distiller's grains is to distill fresh distiller's grains directly or after a period of accumulation and fermentation to burn white wine. Liquid fermentation), and then distilled in an alcohol tower to copy the distiller's grains, and the rema...

AI Technical Summary

Problems solved by technology

In recent years, due to the impact of environmental protection pressure, the pig farming industry in rural areas has decreased sharply. The distiller's grains after liquid fermentation have no way to digest, and the processing cost is high. Feed ingredients sold to feed mills

[0004] However, the distiller's grains still contain about 30% of coarse starch. If they are directly sold at a low price as feed raw materials, not only the added value of the product is not high, but also a large amount of starchy raw materials are wasted, which is not conducive to the development of enterprises.
