A kind of base liquor of Fen-flavor liquor improved by membrane distillation and membrane distillation method thereof

Abstract

The invention relates to a base liquor of Fen-flavor liquor that has been upgraded through membrane distillation and a membrane distillation method thereof, and belongs to the technical field of brewing production. The base wine of the membrane distillation fragrance type liquor of the present invention comprises the following components: ethyl acetate 0.6-2.6g / L, ethyl lactate 0.4-2.4g / L, ethyl caproate 0.01-0.02g / L, isoamyl alcohol 0.4 -0.6g / L. The content and proportion of each component in the base wine of membrane distillation fragrance type liquor of the present invention are reasonable and coordinated, and the quality and flavor are good, so that the wine quality of the base wine that cannot be used for blending pure grain solid-state fermented wine is improved, and the cost of wine body blending is reduced. Difficulty, so that the system of Chinese liquor with extremely complex components can be optimized, so that the base liquor of the existing Fen-flavor liquor with unreasonable components can achieve a better balance, so that its quality is improved and the 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 Fen-flavor liquor that has been upgraded by membrane distillation and its membrane distillation method, which belongs to brewing production. technology field. Background technique [0002] Baijiu is also called shochu. It is a kind of distilled liquor unique to China. It is made from starchy raw materials, added with sugar starter, fermented in solid, semi-solid or liquid state, distilled, stored, and blended. 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 i...

AI Technical Summary

Problems solved by technology

[0026] The present invention aims to solve the inconsistency of the component proportions in the base wine of the existing Fen-flavor liquor, which leads to low quality and unmellow flavor, and the problems existing in the quality and flavor control of Chinese liquor when membrane distillation technology is applied in other fields, and overcomes other problems. Deficiencies, provide a base liquor of Fen-flavor liquor that has been upgraded by membrane distillation, to achieve the purpose of reasonable and coordinated component content and ratio, and good quality and flavor
