Problems solved by technology

It shows that this method has no obvious removal effect on the two harmful impurities of methanol and fusel oil, and cannot solve the technical problem of getting on the head after drinking
In addition, the method adopts a porous material container with a catalyst, the catalyst being TiO 2 or activated carbon, the porous material SiC or Al ２ o ３ , these materials may contain other impurities, which are introduced into the processed base wine and bring new hazards
[0006] Invention patent CN104479978B "Liquor aging agent, aging aging method and aging tank", discloses a liquor aging agent, aging aging method and aging tank, using a fibrous iron-loaded attapulgite base to accelerate aging Additives and attapulgite are mixed, granulated and calcined to make 10-20 mesh granules as a liquor aging agent for industrial production; these materials may contain other impurities, which are introduced into the treated base wine to bring new harm
Although the above methods have a certain effect on promoting the aging of liquor to varying degrees, the effect on removing impurities in liquor is not obvious
And all belong to physical and chemical methods, which may bring new impurities
Adopt a kind of biochemical method to remove the related method of impurity in liquor, have not yet been reported

Embodiment 1

[0020] Take 2kg of raw eggs, remove the egg shells, put them into a container, stir them evenly with an electric mixer, add them into 22.5L of 60% white wine (old-fashioned sorghum shochu) base wine, and stir them well until they are even. At room temperature of 25°C, a light yellow precipitate gradually formed, which was left standing for 4 days. When a large amount of flocculent precipitate appears at the bottom of the container, filter the light yellow precipitate with a filter cloth to obtain the filtrate, put the filtrate into a wine still for distillation, take the wine whose distillation temperature is below 90 degrees, and obtain the processed wine of 75 degrees base wine.

[0021] The analysis results of some trace components by gas chromatography are shown in Table 1.

Embodiment 2

[0025] Example 2: Take 1.5kg of raw eggs, remove the shells, put them into a container, stir them evenly with an electric mixer, add them into 1.8L of 45% white wine (old-fashioned corn shochu) base wine, and stir them well until they are even. At room temperature of 30°C, a light yellow precipitate gradually formed, which was left standing for 6 days. When a large amount of flocculent precipitate appears at the bottom of the container, filter the light yellow precipitate with a fine gauze to obtain the filtrate, put the filtrate into a wine still for distillation, take the wine whose distillation temperature is below 90 degrees, and obtain the processed wine of 75 degrees base wine.

[0026] The main component index analysis results of gas chromatography analysis are shown in Table 2.

Abstract

The invention provides a biochemical method for removing impurities in Baijiu and provides a method for removing the impurities in the Baijiu by utilizing a bioactive substance. According to the biochemical method provided by the invention, one bioactive substance (whole egg liquid, i.e., raw eggs without egg shells (containing egg white and yolks)) has a mutual effect with the impurities in the Baijiu to be subjected to biochemical reaction; then filtering and distillation methods are carried out to obtain the treated Baijiu. By adopting the biochemical method provided by the invention, the impurities in the Baijiu can be effectively removed, so that the treated Baijiu has a soft taste, people do not get headache after drinking the Baijiu, the discomfort is reduced and damages, caused byharmful substances in the Baijiu, to human bodies are reduced. The biochemical method provided by the invention has the advantages of low requirements on equipment, low technical threshold, short response time, simplicity in operation and low cost. An old distillery does not need to be transformed in a large scale, so that a lot of funds can be saved.

Description

technical field [0001] The invention relates to a method for removing impurities in liquor, a biochemical method for removing impurities in liquor by using biologically active substances, and belongs to the technical field of brewing. Background technique [0002] In the brewing process of liquor, in addition to mainly producing ethanol, alcohols, aldehydes, ketones, acids, esters and other catabolites and their derivatives will also be produced. This causes the base liquor that just distills to have the disadvantages of pungent, bursting, strong irritation and bad taste. Some of the substances have toxic effects on the human body, and the most common reaction is headache (commonly known as the top of the head). The main cause of dry mouth and headache after drinking liquor is the high content of methanol, acetaldehyde, and fusel oil in the liquor. Whether there will be any discomfort in the body after drinking is a problem that consumers are very concerned about today, an...
