Problems solved by technology

Whether it is preparing e-liquid or directly heating shredded tobacco, if the tobacco components have not undergone the combustion process of traditional cigarettes, it is difficult for smokers to obtain the unique sensory enjoyment of traditional cigarettes, and traditional tobacco extracts and existing flavors and fragrances cannot make up for this defect
[0007] In the prior art, there are few researches on tobacco carbonization technology, and the research mainly focuses on carbonization equipment, process flow and nicotine extraction. As for the influence of carbonization process on the components of tobacco carbonization extract, there is a lack of systematic research

Embodiment 1

[0034] Weigh 4g of shredded tobacco and put it into a tube furnace, heat it to 200°C, and keep the temperature constant for 2.5h. Use nitrogen to bring the flue gas generated by thermal cracking into the absorption bottle placed in the cold trap. The absorption bottle is pre-installed with 25mL propylene glycol , the temperature of the cold trap is -15°C, and the smoke condensate in the pipeline is washed out with 40mL propylene glycol, and the absorption liquid in the absorption bottle is combined with the smoke condensate washed out in the pipeline to obtain tobacco essential oil.

[0035] The obtained tobacco essential oil was analyzed by GC-MS, and it was identified that there were 11 kinds of aroma components that contributed to the senses but did not exist in tobacco itself, namely benzyl alcohol, maltol, 3-hydroxy-β-damascenone, and benzoic acid. , Pyridine, 2-picoline, 5-methylfurfural, 1-methylpyrrole-2-carbaldehyde, 2-formylpyrrole, 2-acetylpyrrole, 5-hydroxymethyl-2-...

Embodiment 2

[0037] Weigh 4g of shredded tobacco and put it into a tube furnace, heat it to 400°C, and keep the temperature constant for 3h. The flue gas generated by heating and cracking is brought into the absorption bottle placed in the cold trap with nitrogen gas. The absorption bottle is pre-installed with 25mL propylene glycol. The temperature of the cold trap is -15°C, and the smoke condensate in the pipeline is washed out with 40mL propylene glycol, and the absorption liquid in the absorption bottle is combined with the smoke condensate washed out in the pipeline to obtain tobacco essential oil.

[0038] The obtained tobacco essential oil was analyzed by GC-MS, and it was identified that there were 18 kinds of aroma components that contributed to the senses but did not exist in tobacco itself, namely 2,3,4-trimethyl-2-cyclopentenone, malt Phenol, 3-hydroxy-β-damascone, pyridine, 2-picoline, 2,6-lutidine, 2-ethylpyridine, 2-furanethanone, 2,4-dimethyl Pyridine, 2,5-lutidine, 2,3-lut...

Embodiment 3

[0040] Weigh 4g of shredded tobacco and put it into a tube furnace, heat it to 500°C, and keep the temperature constant for 3.5h. Use nitrogen gas to bring the flue gas generated by heating and cracking into an absorption bottle placed in a cold trap. The absorption bottle is pre-installed with 25mL propylene glycol. , the temperature of the cold trap is -15°C, and the smoke condensate in the pipeline is washed out with 40mL propylene glycol, and the absorption liquid in the absorption bottle is combined with the smoke condensate washed out in the pipeline to obtain tobacco essential oil.

[0041]The obtained tobacco essential oil was analyzed by GC-MS, and a total of 11 flavor components were identified that contribute to the senses but do not exist in tobacco itself, namely maltol, pyridine, 2-picoline, 2,6-dimethyl Pyridine, 2-ethylpyridine, 2-furan ethyl ketone, 2,4-lutidine, 2,5-lutidine, 2,3-lutidine, 3-ethylpyridine, 2,3 ,6-collidine.

Abstract

The invention discloses a tobacco essence, an extraction method and application thereof. The extraction method comprises following steps of: (1) carrying out heating and pyrolysis operation on tobaccos within the temperature range for heating and pyrolysis of 150 to 1000 DEG C; (2) absorbing heating and pyrolytic products by utilization of a solvent and condensing absorption liquid in order to obtain tobacco essence.The tobacco essence, the extraction method and application thereof have following beneficial effects: a mode of carbonization and pyrolysis is utilized for processing tobacco so that conventional cigarettes undergo complicated reactions including dissociation and maillard during a burning process; cigarette smoke can be restored to the maximum degree by acquired tobacco in order to compensate for defects that novel tobacco products including electronic cigarettes and non-burning cigarettes during heating have insufficient flavors and obscure styles; and without affecting sensory quality of cigarettes, effects of reducing cigarette smoke and avoiding pollution of second hand smoking to the environment are achieved.

Description

technical field [0001] The invention relates to the technical field of tobacco products, in particular to a tobacco essential oil and its extraction method and application. Background technique [0002] Smoking not only harms the health of the smoker himself, but the crowd around the smoker will also be harmed by passive smoking. In order to reduce the pollution and harm caused by smoke to the public environment, it is urgent to develop smoke-free products. The existing technology Among them, new tobacco products such as electronic cigarettes, heat-not-burn cigarettes, snus, and chewing tobacco have appeared, and these new tobacco products have attracted widespread attention from the tobacco industry at home and abroad. [0003] The above-mentioned new tobacco products are emerging strategic products of the tobacco industry. In these new tobacco products, the shredded tobacco has not undergone a combustion process, and most of them are heated at low temperature to release sm...
