Description

Technical Field

[0001] The invention belongs to the technical field of atomizing liquid component design, and particularly relates to a mixed tobacco flavor used in atomizing liquid and a preparation method thereof. Background Art

[0002] As the world is trying to control cigarettes, electronic aerosol generators have developed rapidly as new tobacco products to meet consumers' smoking and health needs. The atomizing liquid of electronic aerosol generators is mainly composed of solvents, nicotine and flavors. Compared with traditional cigarettes, the tobacco flavor of the atomizing liquid of electronic aerosol generators is more dependent on tobacco flavors.

[0003] Tobacco extract as tobacco flavor can restore the original tobacco flavor to the greatest extent, giving cigarettes full smoke, delicate taste and pure tobacco smoking experience. However, when tobacco flavor is applied to atomizer liquid, a single type of tobacco flavor often leads to a poor smoking experience. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a mixed tobacco flavor for use in an atomized liquid, comprising Virginia tobacco absolute oil and Zimbabwe tobacco fractionated extract in a weight ratio of 1 to 3:1.

[0005] Preferably, the weight ratio of Virginia tobacco absolute oil to Zimbabwe tobacco fractionated extract is 2:1.

[0006] The present invention also provides a method for preparing the mixed tobacco flavor used in the atomized liquid:

[0007] (1) Preparation of Virginia Tobacco Absolute Oil

[0008] After fully extracting Virginia tobacco extract with a weakly polar organic solvent, the extract is concentrated and then added to ethanol for dissolution, the resulting solution is allowed to stand at low temperature for stratification, and the upper layer solution is taken and concentrated to obtain Virginia tobacco absolute oil;

[0009] (2) Preparation of Zimbabwean tobacco fraction extract

[0010] Adding Zimbabwean tobacco extract to ethanol to dissolve, standing the obtained solution at low temperature to separate layers, taking the upper layer solution, and concentrating it to obtain Zimbabwean tobacco absolute oil, and then molecularly distilling the obtained Zimbabwean tobacco absolute oil, and the distilled light component is the Zimbabwean tobacco fractionation extract;

[0011] (3) The Virginia tobacco absolute obtained in step (1) and the Zimbabwe tobacco fractionated extract obtained in step (2) are mixed evenly.

[0012] Preferably, in step (1), the weakly polar organic solvent is one or a combination of petroleum ether, n-hexane, cyclohexane, diethyl ether, dichloromethane, chloroform, and ethyl acetate.

[0013] Preferably, in step (1), the mass amount of the weak polar organic solvent is 1 to 10 times the mass of Virginia tobacco extract.

[0014] Preferably, in step (1), the mass amount of ethanol used is 1 to 10 times the mass of the concentrated extract.

[0015] Preferably, in step (1), the ethanol is anhydrous ethanol or an ethanol aqueous solution with a volume concentration of more than 95%.

[0016] Preferably, in step (1), the low temperature is -20°C to -10°C, and the standing time at low temperature is 10h to 15h.

[0017] Preferably, in step (2), the mass amount of ethanol is 1 to 10 times the mass of Zimbabwe tobacco extract.

[0018] Preferably, in step (2), the ethanol is anhydrous ethanol or an ethanol aqueous solution with a volume concentration of more than 95%.

[0019] Preferably, in step (2), the low temperature is -20°C to -10°C, and the standing time at low temperature is 10h to 15h.

[0020] Preferably, in step (2), the treatment conditions of molecular distillation are as follows: heating temperature of 50-70°C, evaporation temperature of 80-150°C, condensation temperature of the first stage of 10°C-40°C, condensation temperature of the second stage of 10°C--10°C, condensation temperature of the third stage of -10°C--30°C, rotation speed of 100-300 r / min, vacuum degree of 10-200 Pa, and flow rate of 0.5-3 ml / min.

[0021] In this scheme, Virginia tobacco pure oil and Zimbabwe tobacco fractionated extract are mixed in a mass ratio of 1 to 3:1, which not only ensures the flue-cured tobacco aroma of Virginia tobacco, but also has the unique sweet and burnt aroma of Zimbabwe tobacco. Compared with a single tobacco or a compound flavor exceeding the above-mentioned ratio range, the smoke aroma, coordination, miscellaneous smell, irritation, and aftertaste of the tobacco flavor in this scheme are significantly improved, and there is no burnt smell, which means that the tobacco flavor in this scheme is not carbonized, thereby ensuring the atomization quality.
