Method for separating and preparing key acid flavor components in cigarette mainstream smoke and application of key acid volatile components

Abstract

The invention relates to a method for separating and preparing key acid flavor components in cigarette mainstream smoke. The method takes the acidic components in the cigarette mainstream smoke as a raw material, the acidic components in the cigarette mainstream smoke are subjected to linear gradient elution through medium-pressure prepared liquid chromatography, and the same volumes of eluted fractions are sequentially collected; and the gas chromatography-mass spectrometry is adopted to analyze all the eluted fractions, and with the help of sense smoke panel test, three key acid flavor components F4, F5 and F6 are screened finally. The result shows that the fraction F4 has obvious functions of improving smoke impact, increasing smoke concentration and reducing stimulation; the fraction F5 has obvious functions of improving aroma quality and smoke impact and increasing smoke concentration as well as the functions of increasing aroma quantity, covering miscellaneous gases and improving permeability; and the fraction F6 has the obvious functions of improving aroma quality, increasing aroma quantity, improving permeability and smoke impact and increasing smoke concentration as well as the function of improving residual taste.

Description

technical field

[0001] The invention belongs to the field of separation and preparation of tobacco aroma components, in particular to a method for separation and preparation of key acidic aroma components in cigarette mainstream smoke. Background technique

[0002] The aroma components of cigarette smoke are one of the important indicators for evaluating the quality of tobacco and cigarettes. Clarifying the composition of key aroma components in smoke and their impact on cigarette quality plays an important technical role in improving cigarette quality.

[0003] According to the difference in the acidity and alkalinity of the compounds, the particulate matter in mainstream cigarette smoke can be separated into four parts: neutral, weak acid (phenol), acidic and alkaline. Studies have shown that acidic flavor components can adjust the pH of smoke, reduce irritation, make smoke mellow and comfortable, and make an important contribution to the quality of cigarettes.
