[0018] Separation method of burnt-sweet aroma components in mainstream smoke of Brazilian Luzhou-flavor single-material tobacco

[0019] According to the method stipulated in ISO3308 and GB / T 19609-2004, smoke 40 Brazilian strong-flavor single-material cigarettes on the smoking machine, extract the Cambridge filter with 60 ml of dichloromethane, remove the solvent, then add 10 ml of water, and shake fully Afterwards, freeze-dry to obtain the water-soluble components of mainstream smoke. Weigh 0.5 g of the above-mentioned water-soluble components, and use gel permeation chromatography to separate them. The filler is Sephadex G-10, distilled water is used as the mobile phase, and the flow rate is 3 mL / min. The collection process is monitored by an ultraviolet detector with a detection wavelength of 365 nm.

[0020] The automatic fraction collector collects a fraction every 3 minutes, and a total of 40 fractions are collected, labeled as F1, F2, F3, F4, F5, F6...F40. According t...

[0030] Separation method of burnt-sweet aroma components in mainstream smoke of Dajinyuan cigarettes

[0031] According to the methods specified in ISO3308 and GB / T 19609-2004, smoke 20 Dajinyuan cigarettes on a smoking machine, the ambient temperature is 22±2°C, and the humidity is 60±5%. Extract the Cambridge filter with 40 milliliters of ethyl acetate and remove the solvent, add 10 milliliters of water, shake fully, filter with a filter membrane with a pore size of 0.22 microns, freeze-dry to remove water, and obtain the water-soluble component of the mainstream smoke particulate matter. Weigh 0.5 g of the above-mentioned water-soluble components and separate them by gel permeation chromatography. The chromatographic column filler is Sephadex G-20, distilled water is used as the mobile phase, and the flow rate is 3 mL / min. The collection process is monitored by an ultraviolet detector with a detection wavelength of 365 nm.

Abstract

The invention discloses a method for separating a neutral aroma component from mainstream cigarette smoke. The method is characterized by comprising the following specific steps of (1) extracting cambridge filter mainstream smoke condensate from an organic solvent phase; (2) performing water-phase extraction on a smoke extract to obtain a water-soluble component; (3) performing gel permeation chromatographic fractional separation on the water-soluble component; (4) separating out the neutral aroma component by liquid chromatographic separation. According to the method for separating the neutral aroma component from the mainstream cigarette smoke, an aroma rating method (GB / T14454.2-2008) in the field of essences and flavors is introduced into the research on aroma component of cigarettes to instruct gel permeation chromatographic fractional separation and the liquid chromatographic separation of the water-soluble component of the mainstream smoke; furthermore, eluted fractions are screened to find out a series of components with neutral aroma, such as methyl cclopentenolone, strawberry furanone and maltol. According to the separation method, no acidic and alkaline reagent is added, and the pH is not obviously changed; furthermore, the separation and extraction efficiency is high; the number of required cigarettes is small. The method disclosed by the invention can be used as a portable method for screening the neutral aroma component in cigarettes.

Description

technical field [0001] The invention belongs to the technical field of separation and identification, and in particular relates to a method for separating burnt-sweet aroma components in cigarette mainstream smoke, that is, a method for extracting and separating burnt-sweet aroma components from smoke condensate. Background technique [0002] Burnt sweet aroma is an important part of flue-cured tobacco aroma, which has a crucial impact on the sensory quality of cigarettes, and has received extensive attention from domestic and foreign tobacco companies. The burnt sweet aroma is produced during the smoking process of cigarettes, and is mainly produced by the high-temperature degradation of carbohydrates. In 1971, Elmenhorst first discovered maltol with burnt sweetness from cigarette condensate ( Acta Chemica Scandinavica , 1990, 44 , 916). Since then, Japanese, Swedish and other tobacco companies have carried out in-depth research on the burnt-sweet aroma of cigarettes, an...
