A kind of base wine of medicinal-flavor liquor upgraded by membrane distillation and membrane distillation method thereof

Abstract

The invention relates to a base liquor of medicinal-flavor liquor improved by membrane distillation and a membrane distillation method thereof, and belongs to the technical field of brewing production. The base liquor of the membrane-distilled medicinal-flavor liquor of the present invention comprises the following components: ethyl acetate 0.8-1.8g / L, ethyl caproate 0.5-1.0g / L, ethyl lactate 0.4-0.7g / L, ethyl butyrate Ester 0.15-0.4g / L, isoamyl alcohol 0.4-0.9g / L. The content and proportion of each component in the base wine of the membrane distillation medicinal-flavor liquor of the present invention are reasonably coordinated, and the quality and flavor are good, so that the quality of the base wine that cannot be used for blending pure grain solid-state fermented wine is improved, and the blending of the wine body is reduced. The difficulty of making Chinese liquor, which has extremely complex components, can be optimized, so that the base liquor of medicinal-flavored 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 medicinal-flavor 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 wa...

Problems solved by technology

[0026] The present invention aims to solve the problems existing in the control of the quality and flavor of Chinese liquor by applying the membrane distillation technology in other fields to the uncoordinated proportion of ingredients in the base liquor of the existing medicinal-flavored liquor, resulting in low quality and unmellow flavor. Its defect is to provide a base wine of medicinal-flavored liquor that has been upgraded by membrane distillation, so as to achieve the purpose of reasonable and coordinated component content and proportion, and good quality and flavor
