Embodiment 1

[0017] Get 200g white hair tobacco leaves, grind it to 50 mesh and carry out subcritical extraction: extraction pressure 0.78MPa, extraction temperature is room temperature, extraction solvent is dimethyl ether, solid-liquid ratio is 1:8, entrainer is 95% ethanol, The amount of entrainer is 1.5 times of the raw material, and the extraction time is 1h. After the extraction is completed, the extraction mixture enters the separation tank, and the extraction solvent is separated by the principle of reduced-pressure evaporation to obtain the fume extract. Add 5 times the mass of 95% ethanol to the above extract under stirring, heat to 50 o C and kept for 30min to fully dissolve, cooled to room temperature and transferred to the refrigerator (-5 o C) Freezing for 24 hours; after suction filtration, the filtrate was concentrated under reduced pressure until no ethanol was present, to obtain kerosene absolute. The above-mentioned hair fume absolute is transferred to the feed tank of...

Embodiment 2

[0021] Take 200g of Yunnan hairy tobacco raw material, crush it to 100 mesh and carry out subcritical extraction: the extraction pressure is 0.89MPa, and the extraction temperature is 40 o C, the extraction solvent is propane, the ratio of solid to liquid is 1:15, and the extraction time is 1.5h. After the extraction is completed, the extraction mixture enters the separation tank, and the extraction solvent is separated by the principle of reduced-pressure evaporation to obtain the fume extract. Add 10 times the mass of 95% ethanol to the above extract under stirring, heat to 40 o C and kept for 50min to fully dissolve, cooled to room temperature and transferred to the refrigerator (-20 o C) Freezing for 8 hours; after suction filtration, the filtrate was concentrated under reduced pressure until no ethanol was present, to obtain kerosene absolute. The above-mentioned hair fume absolute is transferred to the feed tank of molecular distillation, and the parameters are set as ...

Embodiment 3

[0025] Get 200g of fumao tobacco leaves, grind it to 10 meshes and carry out subcritical extraction: the extraction pressure is 0.45MPa, and the extraction temperature is 50 o C, the extraction solvent is butane, the ratio of solid to liquid is 1:10, and the extraction time is 0.5h. After the extraction is completed, the extraction mixture enters the separation tank, and the extraction solvent is separated by the principle of reduced-pressure evaporation to obtain the fume extract. Add 8 times the mass of 95% ethanol to the above extract under stirring, heat to 30 o C and kept for 60min to make it fully dissolved, cooled to room temperature and transferred to the refrigerator (-10 o C) freezing for 12 hours; centrifuging the supernatant (4000 rpm, 30 min), and concentrating the supernatant under reduced pressure until ethanol-free, to obtain kerosene absolute. The above-mentioned hair fume absolute is transferred to the feed tank of molecular distillation, and the parameters...

Abstract

A method for preparing hair tobacco essential oil, characterized in that: using combined technology of subcritical extraction and molecular distillation to extract and separate hair tobacco as a raw material, so as to effectively increase the content of volatile aroma substances in the essential oil. Applying tobacco essential oil to cigarettes can improve the aroma quality and taste of cigarettes, and improve the sensory comfort of cigarettes; applying tobacco essential oil to e-cigarette liquids can give e-cigarettes a strong aroma of tobacco and enhance the sense of satisfaction , reduce the sweetness of the solvent. The biggest features of the present invention are: (1) Compared with steam distillation, the extraction rate of essential oil is greatly improved; (2) The combination of subcritical extraction and molecular distillation technology reduces the content of non-volatile macromolecular substances in essential oil, The content of volatile aroma substances is increased, among which the content of nicotine, solanone, neophytadiene, macrostigmatrienone, farnesyl acetone, etc. is significantly increased compared with subcritical extracted absolute oil, making the characteristic aroma of tobacco more for highlighting.

Description

technical field [0001] The invention relates to the field of extraction and application of natural plant essential oils, in particular to a preparation method of hair tobacco essential oil and its application in cigarettes and electronic cigarettes. Background technique [0002] In recent years, with the reduction of the tar content of cigarettes, low-tar cigarettes have weaker smoke taste, weaker aroma, and weakened style characteristics of cigarette products, which are difficult to be accepted by consumers. Therefore, while reducing the harm and coke of cigarettes, increasing the flavor of cigarettes and increasing the concentration of smoke is an urgent problem to be solved. Cigarette flavoring can make up for the lack of flavor in the formula of cigarette leaves, and is one of the effective means to improve product style and improve the quality of cigarette aroma. Tobacco extract is a compound extracted and separated from tobacco raw materials. It has good coordination ...
