Abstract

The invention provides a Blue Dream white liquor aroma component concentrating method. Blue Dream white liquor is measured and is added into a container, then a saturated salt solution is added, mixing is performed to obtain a solution to be extracted, wherein the volume ratio of the Blue Dream white liquor to the salt solution is 1:3-7; a mixed solution of dichloromethane, diethyl ether and hexane is added into the solution to be extracted, continuous extraction is performed to obtain an upper-layer organic phase, moisture in the organic phase is removed, and then filtration is performed by adopting a filter membrane; the mixed solution obtained after filtration by adopting the filter membrane is added into an impalement type fractionation device, the fractionation device is put into a constant-temperature water bath kettle of 45-55 DEG C to perform impalement type fractionation and concentration, and the mixed solution subjected to impalement type fractionation and concentration is concentrated by using a pressure blowing concentrator to obtain a Blue Dream white liquor aroma component. The Blue Dream white liquor aroma component concentrating method is simple and convenient to operate, capable of saving time and effort and low in cost, can play enrichment and concentration roles on minor components, facilitates qualitative and quantitative analysis on extremely trace amounts of substance, meanwhile effectively reduces loss of volatile components and improves the recovery rate of aroma substance.

Description

technical field [0001] The invention belongs to the field of food science and relates to Mengzhilan Baijiu, in particular to a method for concentrating the aroma components of Mengzhilanbaijiu. Background technique [0002] Aroma is one of the factors that affect the quality of liquor. Through the analysis of the aroma components of Mengzhilan Baijiu, the identification of the characteristic aroma components of the liquor is of great significance for improving the quality of the liquor. [0003] At present, the concentration methods of the aroma components of wine mainly include: nitrogen blowing method, rotary evaporation method, vacuum centrifugal concentration method and K-D concentration method. However, these methods have their own advantages and disadvantages. Because more organic solvents are used during wine extraction, such as nitrogen blowing and rotary evaporation, the highly volatile aroma substances are easily lost, and trace components are difficult to analyze...
