A kind of base wine of fragrance-flavored liquor improved by membrane distillation and membrane distillation method thereof

Abstract

The invention relates to base liquor of fragrant scent liquor extracted by membrane distillation and a membrane distillation method thereof, and belongs to the technical field of liquor making production. The base liquor of the fragrant scent liquor extracted by the membrane distillation comprises the following components: 95-174mg / 100mL of ethyl acetate, 87-140mg / 100mL of ethyl caproate, 53-72mg / 100mL of ethyl lactate, 16-29mg / 100mL of ethyl butyrate, 2-6mg / 100mL of ethyl formate and 34-44mg / 100mL of isoamyl alcohol. According to the base liquor of the fragrant scent liquor extracted by the membrane distillation, the contents and proportions of the components are reasonably coordinated, the quality and flavor are better, the vinosity of the base liquor which originally can not be used for being blended with pure grain solid-state brewed liquor is improved, the difficulty of liquor blending is reduced, the extremely-complex system of the components of Chinese liquor is optimized and processed, the existing base liquor of the fragrant scent liquor with the unreasonable components achieves better balance, the quality of the base liquor is improved, and the flavor is more mellow and normal.

Description

technical field [0001] The 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 fragrance-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 warehous...

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 proportions of the ingredients in the base liquor of the existing fragrant-flavor liquor, resulting in low quality and unmellow flavor. Its defect is to provide a base wine of fragrant and fragrant 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
