A base wine of sesame-flavor liquor improved by membrane distillation and membrane distillation method thereof

Abstract

The invention relates to a base liquor of sesame-flavored liquor that has been upgraded through membrane distillation and a membrane distillation method thereof, belonging to the technical field of winemaking production. The base liquor of the film distillation sesame flavor liquor of the present invention comprises the following components: ethyl acetate 0.4-2.5g / L, ethyl lactate 0.2-2.2g / L, ethyl caproate 0.1-1.2g / L, 3-methyl Thiopropanol 0.5-200mg / L, Isoamyl Alcohol 0.2-0.6g / L. The content and proportion of each component in the base liquor of the film distillation sesame-flavored liquor of the present invention are reasonable and coordinated, and the quality and flavor are good, so that the quality of the base liquor that cannot be used for blending pure grain solid-state fermented liquor is improved, and the blending of liquor body is reduced The difficulty of making Chinese baijiu, a system with extremely complex components, has been optimized, so that the base wine of sesame-flavored baijiu with unreasonable components can achieve a better balance, so that its quality is improved and its flavor is more mellow and positive.

Description

technical field [0001] The present invention relates to a base liquor of liquor and its preparation method in brewing production, more specifically, the present invention relates to a base liquor of sesame-flavored liquor upgraded by membrane distillation and its membrane distillation method, which belongs to liquor brewing field of production technology. Background technique [0002] Liquor, also known as shochu, is a kind of distilled liquor unique to China. It is made from starchy raw materials, adding sugar starter, solid, semi-solid or liquid fermentation, distillation, storage, and blending. The semi-finished wine that has been distilled from the fermented grains and temporarily stored in the warehouse to be graded is habitually called "original wine" in the industry. The alcohol content of original wine is generally 60-80%vol. After the original wine is graded and classified, it will be combined and put into the warehouse for aging. The original wine aged in the war...

AI Technical Summary

Problems solved by technology

[0027] The present invention aims to solve the problems existing in the control of the quality and flavor of Chinese liquor by applying membrane distillation technology in other fields to the uncoordinated proportion of ingredients in the base liquor of the existing sesame-flavored liquor, resulting in low quality and unmellow flavor. Its defect is to provide a base wine of sesame-flavored liquor through membrane distillation, which can achieve the purpose of reasonable and coordinated component content and proportion, and good quality and flavor
