Embodiment 1

[0048] Separation of weakly acidic aroma components in the particulate matter of high-quality cigarette smoke:

[0049] (1) Extraction:

[0050] On the rotary smoking machine, the filter capture method is adopted, and the Cambridge filter (92mm in diameter, each Cambridge filter collects 20 cigarette smoke particles) is used to collect high-quality tobacco smoke particles, and the Cambridge filter is obtained Captures: 30 pieces of Cambridge filter captures that capture high-quality cigarette smoke particles are first soaked in ether for extraction, then ultrasonically extracted for 5 minutes, then shaken for 30 minutes, left for one day, and then extracted again to obtain the extracted liquid. Concentrate the obtained extract under reduced pressure to obtain the concentrated solution O of the dark brown crude extract, that is, the diethyl ether solution of the dark brown crude extract; wherein, the vacuum degree of the reduced pressure concentration is 870 mbar, and the temp...

Embodiment 2

[0069] Separation of weakly acidic aroma components in the particulate matter of high-quality cigarette smoke:

[0070]In addition to the vacuum concentration obtained in step (1) to obtain the concentrated solution O of the dark brown crude extract after concentrating the extract under reduced pressure, the vacuum degree of the concentration under reduced pressure is 500mbar, and the temperature of the water bath is 60°C, and the step (2.4) reduces The vacuum concentration of the organic phase extract O3 obtained after concentration under pressure is 500 mbar, and the temperature of the water bath is 60 ° C. Other separation steps are the same as in Example 1, and finally the target weakly acidic fragrance component SF14 is obtained.

[0071] The weakly acidic fragrance component SF14 obtained in this example is detected by GC-MS, and its main fragrance substance is 3-methyl-2-hydroxycyclopentenone. The weakly acidic fragrance component SF14 was redissolved with ethanol to pr...

[0074] Separation of weakly acidic aroma components in the particulate matter of high-quality cigarette smoke:

[0075] In addition to obtaining the extract obtained in step (1) after being concentrated under reduced pressure to obtain the concentrated solution O of the dark brown crude extract, the vacuum degree of concentration under reduced pressure is 1000mbar, and the temperature of the water bath is 25 ° C, and the step (2.4) reduces The vacuum concentration of the organic phase extract O3 obtained after concentration under pressure is 1000 mbar, and the temperature of the water bath is 25°C. Other separation steps are the same as in Example 1, and finally the target weakly acidic fragrance component SF14 is obtained.

[0076] The weakly acidic fragrance component SF14 obtained in this example is detected by GC-MS, and its main fragrance substance is 3-methyl-2-hydroxycyclopentenone. The weakly acidic fragrance component SF14 was redissolved with ethanol to prepare a sol...

Abstract

The invention relates to separation of critical phenols and weak acidic trace aromatic components in cigarette mainstream smoke, especially separation method of trace aromatic components from large amount of harmful components. The invention takes unblended cigarette of high-quality tobacco leaf as material. Collected smoke particulate phase condensate is subjected to steps of extraction, acid washing, alkali washing, vacuum concentrating, normal phase liquid phase chromatographic separation, etc., to give six elution fractions F1-F6, which are subjected to gas chromatography-mass spectrometry (GC-MS) analysis in combination with sensory evaluation, to select elution fraction F4 with obvious sensory effect. Through further preparative liquid phase chromatography separation method and combination of chemical analysis and sensory evaluation, separation and purification are further performed to enrich aromatic fraction, finally weak acidic aromatic component SF14 is screened. The inventive separation method removes large amount of components without contribution to cigarette aroma, enriches trace beneficial aromatic components, uses them in flavoring field of tobacco shred or filter tip, and is necessary for improving smoking quality of cigarette.

Description

technical field [0001] The invention relates to the separation of key phenols and weakly acidic trace flavor components in cigarette mainstream smoke, in particular to a separation method for separating trace flavor components from a large number of harmful components. Background technique [0002] The phenols and weakly acidic components in cigarette smoke mainly include phenols and ketone alcohols. Among them, there are 444 kinds of phenols in the smoke, mainly simple phenols, and contain a small amount of polyphenols, phenolic acids and quinones. Phenols are mainly derived from the cracking of monosaccharides, cellulose, pectin, chlorogenic acid, rutin and other polyphenolic components during the burning process of cigarettes. The role of phenols in smoke is relatively complicated. Due to their strong volatility, these compounds directly enter the smoke through evaporation and other channels during smoking, and have a direct impact on the aroma of the smoke. Some have sp...
