Problems solved by technology

[0004] At present, low-temperature (below -16°C) filtration is mostly used to reduce the turbidity of liquor, but this method is limited by the temperature, and the removal rate is only about 80%.
In addition, the more common method at present is the method of using activated carbon or other media for adsorption. This method has a low removal rate and will lose various trace components produced during the fermentation process.
Moreover, most of the current methods use finished wine as a raw material to remove the substances that cause the liquor to become turbid after the alcohol is reduced. However, most of the finished wines are prepared, the volume increases and the concentration of the target substance is low, which increases the difficulty of removing turbidity.
[0005] It can be seen that the current problem of reducing the turbidity of liquor has not been well resolved, and the method of removing turbidity in liquor still needs further research

Embodiment 3

[0072] Adopt gas chromatography internal standard method to detect the content of higher fatty acid ethyl ester (ethyl palmitate, ethyl oleate, ethyl linoleate) in liquor base liquor and embodiment 1~2 gained fraction 1~5, the result As in Table 1:

[0073] Table 1 Content of higher fatty acid ethyl ester

[0074]

[0075] Except for fraction five, fraction one and fraction three were not detected to contain higher fatty acid ethyl esters, indicating that the method provided by the present invention can effectively remove higher fatty acid ethyl esters, and the removal rate can reach 94.5%. Higher fatty acid ethyl esters are the main substances that cause the liquor base wine to become turbid after the alcohol is reduced. The present invention uses the content of these substances to measure the effect of removing turbidity. The results show that the method provided by the invention has a good effect of removing turbidity and can improve the quality of the finished wi...

Abstract

The invention relates to the technical field of food, in particular to a method for removing turbidity of liquor base. The method for removing the turbidity of the liquor base comprises steps as follows: firstly, to-be-removed substances resulting in turbidity after liquor alcohol reduction are enriched through two-step distillation, and then the substances are removed through low-temperature filtering. According to the method, the removal rate of the substances resulting in the turbidity after liquor alcohol reduction can be up to 95%, main aroma matters in the base are not reduced obviously, and the sensory attributes of the base are not damaged. Besides, the base is directly taken as a raw material for removing the turbidity, compared with a finished liquor product as a target, the size is smaller, the operation is more convenient, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of food, in particular to a method for removing turbidity from liquor-based liquor. Background technique [0002] In recent years, due to the country's promotion of the development of low-alcohol liquor, as well as the media's publicity and changes in consumer consumption habits, medium and low-alcohol liquor has been greatly developed, while the production and sales of high-alcohol liquor have shrunk. According to the survey, the current low-alcohol liquor with an alcohol content below 40° has accounted for 36% of the total liquor production, the moderate liquor with an alcohol content of 40°-50° has accounted for 50%, and the high-alcohol liquor with an alcohol content above 50° Alcohol accounts for only 14%. [0003] For the quality of liquor, not only the taste and style corresponding to its fragrance type are required, but also the clarity and transparency of the liquor body is required. However, as t...
