Base liquor of sesame-flavor liquor upgraded by membrane distillation and membrane distillation method thereof

Abstract

The invention relates to base liquor of sesame-flavor liquor upgraded by membrane distillation and a membrane distillation method thereof, belonging to the technical field of wine production. The base liquor of membrane distillation sesame-flavor liquor provided by the invention comprises the following ingredients: 0.4-2.5 g / L of ethyl acetate, 0.2-2.2 g / L of ethyl lactate, 0.1-1.2 g / L of ethyl caproate, 0.5-200 mg / L of 3-methylthiopropanol and 0.2-0.6 g / L of isoamyl alcohol. The base liquor of membrane distillation sesame-flavor liquor provided by the invention is reasonable and harmonious in ingredient contents and proportions and excellent in quality and flavor, the quality of the base liquor originally incapable of being used for blending solid fermented pure grain liquor is improved, the blending difficulty of the liquor is reduced, the complex ingredient system of the Chinese liquor is optimized, the existing base liquor of drug-flavor liquor with unreasonable ingredients is better balanced, the quality of the base liquor is perfected, and the flavor of the base liquor is more mellow and normal.

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 wa...

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
