Embodiment 1

[0033] The acidic compound in cigarette mainstream smoke was sampled, and the sample volume was 2.5 mL. A 20 g normal-phase silica gel column (Agela Flash Column Silica) was selected, with a column volume of 40 mL, a diameter of 2.6 cm, and an aspect ratio of 4.2. 40-60μm, the pore size is ) for its linear gradient elution separation preparation. Wherein, during linear gradient elution, 2 times column volume of n-hexane is first used for elution, and then 4 times column volume of n-hexane-ether mixed eluent (the ratio of n-hexane and ether mixed eluent Linear gradient elution from n-hexane and diethyl ether with a volume ratio of 100:0 to a volume ratio of 0:100 n-hexane and diethyl ether), and finally eluted with 2 times column volume of diethyl ether, the flow rate is controlled at 5mL / min . After sample injection, 8 eluted fractions F1-F8 were collected sequentially in equal volume, and each fraction was collected in equal volume of 40 mL. The eluted fractions F1-F8 wer...

Embodiment 2

[0062] The acidic compound in cigarette mainstream smoke was sampled, and the sample volume was 2.5 mL. A 40 g normal-phase silica gel column (Agela Flash Column Silica) was selected, with a column volume of 80 mL, a diameter of 3.1 cm, and an aspect ratio of 4.5. 40-60μm, the pore size is ) for its linear gradient elution separation preparation. Wherein the method of linear gradient elution is the same as in Example 1, and the flow rate is 5mL / min. After sample injection, 8 eluted fractions F1-F8 were obtained by sequentially collecting equal volumes, and each eluted fraction was collected in equal volume of 80 mL. The eluted fractions F1-F8 were analyzed by gas chromatography-mass spectrometry, and the results showed that the key acidic components were mainly concentrated in the eluted fractions F4, F5 and F6, of which F4 was a weak acid (or phenolic) compound, and F5 was a saturated Acid compounds, F6 is an unsaturated acid and aromatic acid compound, the qualitative ana...

Embodiment 3

[0065] The acidic compound in cigarette mainstream smoke was sampled, and the sample volume was 3.5 mL. A 20 g normal-phase silica gel column (Agela Flash Column Silica) was selected, with a column volume of 40 mL, a diameter of 2.6 cm, and an aspect ratio of 4.2. The particle size of the silica gel filler was 40-60μm, the pore size is ) for its linear gradient elution separation preparation. Wherein the method of linear gradient elution is the same as in Example 1, and the flow rate is 5mL / min. After sample injection, 8 elution fractions F1-F8 were obtained by sequentially collecting equal volumes, and 40 mL of each elution fraction was collected in equal volume. The eluted fractions F1-F8 were analyzed by gas chromatography-mass spectrometry, and the results showed that the key acidic components were mainly concentrated in the eluted fractions F4, F5 and F6, of which F4 was a weak acid (or phenolic) compound, and F5 was a saturated Acid compounds, F6 is an unsaturated aci...

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.
