Abstract

The invention relates to the technical field of baijiu brewing, in particular to a method for reducing the content of fusel oil in Xiaoqu liquor. The method includes the processes of grain soaking, primary steaming, grain braising, secondary steaming, spreading cooling, yeast adding, culture saccharification, blended grain fermentation, distillation in a steamer and the like. After culture saccharification is completed, yeast extract powder with the mass being 0.05-0.07% the grain addition amount and ammonium bicarbonate with the mass being 0.02-0.04% the grain addition amount are added into saccharified grains, the concentration of an assimilable nitrogen source is increased, and thus the content of fusel oil is decreased. By means of the method, the problem that the content of fusel oil in Xiaoqu liquor is high is solved, operation is easy and convenient, cost is low, and the quality of liquor is improved; the method is mainly applied to the production process of brewing Xiaoqu baijiu.

Description

technical field

[0001] The invention relates to the technical field of liquor brewing, in particular to a method for reducing the content of fusel oil in Xiaoqu liquor. Background technique

[0002] Fusel oil is a mixture of fatty alcohols with more than 2 carbon atoms and monovalent alcohols with more than three carbon chains. It is the main by-product of ethanol and beer produced by fermentation of cereal crops, including n-propanol, isobutanol, Isoamyl alcohol, active amyl alcohol, phenethyl alcohol, etc., are mainly calculated by the content of isobutanol and isoamyl alcohol in liquor.

[0003] Fusel oil has a high boiling point, and its oxidation rate in the human body is slower than that of ethanol, so it stays in the human body for a long time, which can make the nervous system congested, cause headaches and dizziness, and thus be harmful to the human body. In addition, it also brings evil and miscellaneous flavors to the flavor of liquor, is one of the main sources ...
