Embodiment Construction

[0143] Embodiment 1 of the present invention. The high performance liquid chromatography determination method of volatile phenolic compounds in liquor, comprises the following steps,

[0144] Precisely weigh phenol, guaiacol, p-cresol, m-cresol, o-cresol, 4-methylguaiacol, 4-vinylphenol, 4-ethylphenol, 4-vinyl Each 25 mg of guaiacol and 4-ethyl guaiacol reference substance was used to dilute to 25 mL with 1% glacial acetic acid solution (4-vinylphenol and 4-vinyl guaiacol were distilled to volume with methanol), and into a standard stock solution of 1 mg / mL. Doubling dilution was performed with 1% glacial acetic acid solution to prepare mixed reference substance solutions of phenolic compounds with mass concentrations of 0.02, 0.2, 1.0, 2.0 and 4.0 μg / mL. Linear regression was performed on the mass concentration (X, μg / mL) of the peak area (Y) to establish a calibration curve (also called a regression equation) for 10 volatile phenolic compounds, which was used for quantitat...

Abstract

The invention discloses a high performance liquid chromatography determination method for volatile phenolic compounds in white spirits. By adopting a high performance liquid chromatogram-fluorescence detector (HPLC-FLD) technique to analyze volatile phenolic compounds in white spirits, the method of the invention, when used in analysis of volatile phenolic materials, can determine the following 10 volatile phenolic compounds of phenol, guaiacol, p-cresol, m-cresol, o-cresol, 4-methylguaiacol, 4-vinylphenol, 4-ethylphenol, 4-vinylguaiacol and 4-ethylguaiacol in white spirits. And the method has the advantages of no need for derivatization, high accuracy, high sensitivity and good repeatability.

Description

technical field [0001] The invention relates to a high-performance liquid chromatography determination method for volatile phenolic compounds in liquor, belonging to the technical field of liquor detection. Background technique [0002] Beverage wine usually contains some volatile phenolic substances. They have been found in beer, wine and distilled spirits. Volatile phenolic compounds are important aroma components of drinking wine. Since this type of component plays an important role in the smell, taste and stability of wine, it has attracted the attention of many researchers. [0003] In 1980, the Food Fermentation Research Institute of the Ministry of Light Industry in China took Moutai as the main research object. In the analysis and research of volatile phenolic compounds in liquor by chemical derivation method combined with GC-FID / GC-MS, the pre-treatment was cumbersome and derivation was required. and the addition recovery of 4-methylguaiacol and 4-ethylguaiacol is...
