Embodiment 1

[0014] The application of Paulownia flower extract in cigarettes is specifically:

[0015] Put the fresh paulownia flowers into a constant temperature vacuum oven at 60°C and fully dry them, then cool them naturally in the oven, and take them out. Weigh 100g, pulverize it with a grinder, add it to a 1000 mL round bottom flask, add 375 mL 95% ethanol and 375 mL petroleum ether, heat and reflux in a water bath for 6 h, stop heating, filter while hot, and filter the residue with 95% The mixed solvent of ethanol and petroleum ether (volume ratio 1:1) was washed three times. After the filtrate was cooled, the solvent was evaporated under reduced pressure to obtain a light red viscous liquid, namely natural Paulownia flower extract.

Embodiment 2

[0017] The application of Paulownia flower extract in cigarettes is specifically:

[0018] Put the fresh paulownia flowers into a constant temperature vacuum oven at 60°C and fully dry them, then cool them naturally in the oven, and take them out. Weigh 100g, grind it into a 1000mL round-bottomed flask, add 750mL of petroleum ether, heat and reflux in a water bath for 4 hours, stop heating, filter while hot, wash the residue with petroleum ether three times, and decompress the filtrate after cooling The solvent is evaporated to obtain a light red viscous liquid, which is the natural Paulownia flower extract.

Embodiment 3

[0020] Put the fresh paulownia flowers into a constant temperature vacuum oven at 60°C and fully dry them, then cool them naturally in the oven, and take them out. Weigh 100g, crush it by grinding, add it to a 1000mL round bottom flask, add 750mL 95% ethanol, heat and reflux in a water bath for 7h, stop heating, filter while hot, wash the residue three times with 95% ethanol, and cool the filtrate , and evaporate the solvent under reduced pressure to obtain a light red viscous liquid, that is, the natural Paulownia flower extract.

[0021] Composition analysis of the tobacco spices (extract) prepared in the above examples: Agilent 7890A-5975C GC / MS (Agilent Technologies Co., Ltd., USA) and 400 nuclear magnetic resonance spectrometer (Varian Corporation, USA) were used to analyze and find that The main ingredients are: glucoside, quercetin, kaempferol, high eriodiction, 4,5,7-trihydroxy-3-methoxyflavone, 5-hydroxy-3,4,7-trimethoxy Flavonone, luteolin, acetin, benzaldehyde, van...

Abstract

The application of Paulownia flower extract in cigarettes belongs to the technical field of tobacco processing; specifically: add 95% ethanol and / or petroleum ether to the dried and ground Paulownia pollen, heat and reflux in a water bath for 4-7 hours, and after the reflux extraction Filtrate while hot, wash the residue three times with 95% ethanol and / or petroleum ether solvent, after the filtrate is cooled, evaporate the solvent under reduced pressure to obtain a light red viscous liquid, namely the natural Paulownia flower extract, which is the flavor used for tobacco. The tobacco extract of the present invention has the advantages of simple preparation method, low cost, less energy consumption, stable properties, and no side effects; when added to cigarettes, it can significantly reduce irritation, cover miscellaneous gas, improve aftertaste, reduce bitterness, increase Sweetness, mellow and comfortable aftertaste, the tobacco extract is a new flavor for cigarettes with high quality.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to the application of paulownia flower extract in cigarettes. Background technique [0002] Due to the difference and influence of tobacco leaf types, planting environment, climate, harvesting, baking, natural fermentation and other factors, there are great differences in its appearance, chemical composition, physical properties and internal quality, resulting in the inevitable production of cigarettes. Slight or obvious odor and irritation. Therefore, how to reduce the irritation of cigarettes, cover up the miscellaneous gases of cigarettes, and improve the comfort of smoking cigarettes has become an important research topic in the tobacco industry. [0003] Paulownia is the flower of Paulownia, also known as hibiscus flower in traditional Chinese medicine. It is white in color, with light red markings at the base. The aroma is simple, dense and clear, and t...
