Embodiment 1

[0035] A method for improving the clarity of soft liquor base liquor, comprising the steps of:

[0036](1) Distill the liquor base liquor at 100°C and 95kpa, the distillate is recorded as fraction 1, and the distillation residue is recorded as fraction 2; the fraction 2 is distilled at 50°C and 15kpa, and the distillate is recorded as fraction 3, and the distillation residue is Liquid is recorded as fraction four; fraction four is filtered, and the filtrate is recorded as fraction five; fraction six is ​​obtained by mixing fraction one, fraction three and fraction five; the reflux ratio of distillation is 1:1;

[0037] (2) Add the first part of activated carbon into Fraction 6, and stir for the first time for 3 minutes, then let it stand for 0.4 hours after stirring, then add the second part of activated carbon into Fraction 6, and perform the second stirring for 3 minutes. Stand still for 0.4h for the second time, and finally add the third part of activated carbon to fraction...

Abstract

The invention provides a method for improving the clarity of soft white spirit base liquor. The method comprises the following steps of (1) performing two-step distillation; (2) adding activated carbon for three times; (3) adding chitosan twice; (4) filtering the obtained white spirit base liquor by adopting filter cloth, then filtering the white spirit base liquor by adopting a sand core, and finally filtering the white spirit base liquor by adopting a membrane; (5) detecting the clarity, and if the clarity is not qualified, carrying out secondary clarification until the clarity of white spirit is qualified; and (6) carrying out ultraviolet and ultrasonic treatment on the white spirit. According to the method disclosed by the invention, firstly, substances which cause turbidity after reduction of the alcohol content of the white spirit are enriched through the two-step distillation, then the substances are adsorbed through the activated carbon and the chitosan and are removed through staged filtration; the steps are progressive layer by layer and cooperate; and by the method, the removal rate of the substances which cause turbidity after reduction of the alcohol content of the white spirit can reach 96%, and the sensory quality of the white spirit is not damaged.

Description

technical field [0001] The invention relates to the technical field of liquor production, in particular to a method for improving the clarity of soft liquor base liquor. Background technique [0002] Baijiu is the collective name of domestic alcoholic beverages, also known as shochu, Laobaigan, Shaodaozi, etc. Liquor has a compound aroma with esters as the main body. It is a variety of wines made from koji and distiller's saccharification starter, using starchy raw materials, cooking, saccharification, fermentation, distillation, aging and blending. Grain is used to make it, and liquor will change with the alcohol content and temperature, and the solute in it will become oversaturated, resulting in the formation of crystals. The shapes and colors of the crystals are various, and the shapes include flakes, flocs, needles and powders. The colors are off-white, brown, green, milky white, light yellow, blue-black and so on. Especially liquor-based liquor, which is rich in nut...
