Problems solved by technology

However, tobacco extract usually contains a relatively large proportion of nicotine, and adding a large amount to cigarettes will increase the strength, irritation, and roughness of the cigarette
When the amount added is small, the effect of increasing flavor is poor, and the effect of improving product quality is not obvious

Embodiment 1

[0027] Tobacco leaves in Qujing, Yunnan Province were used as raw materials to prepare low-nicotine tobacco extracts, and the specific steps were as follows:

[0028] 1) Extraction: crush the tobacco raw material, pass through a 30-mesh sieve, add 5 times the mass of acetone to the obtained smoke powder, extract at 50°C for 2 hours, and then filter impurities to obtain a tobacco extract;

[0029] 2) Purification and concentration: add water to wash the tobacco extract for 2 times, and the amount of water added each time is 3 times the mass of acetone used in step 1) and layered, take the upper organic phase, concentrate under reduced pressure to remove acetone, and obtain crude tobacco extract;

[0030] 3) Molecular distillation: Carry out molecular distillation and separation of crude tobacco extract to obtain 2 fractions of light component and heavy component; molecular distillation process conditions are distillation temperature 80°C, distillation pressure 1mbar, scraper spe...

Abstract

The invention discloses a low-nicotine tobacco extract and a preparation method thereof. The preparation method comprises the following steps: firstly, preparing tobacco extract liquid with relatively low nicotine content by extracting through a ketone or ester solvent; secondly, removing a certain amount of nicotine by water washing; thirdly, concentrating for removing the solvent; finally, completely removing the nicotine through molecular distilling to obtain a tobacco extract spice which is very low in nicotine content and higher in fragrance quality. By adopting the preparation method, the treated tobacco extract can be added into cigarettes in a larger amount, the cigarette fragrance can be improved more remarkably, the fragrance and concentration are enhanced, the strength and irritation are not increased basically, and the cigarette quality is improved well.

Description

technical field [0001] The invention belongs to the field of tobacco additives, and relates to a low-nicotine tobacco extract and a preparation method thereof. Background technique [0002] In the process of cigarette design, in order to improve the quality of cigarette products and maintain the stability of the style of cigarette products, it is usually necessary to add certain aroma substances to enhance the flavor of the product. Tobacco extract is the most important type of tobacco flavors. Because it is extracted from tobacco, it has many advantages such as coordination, safety and pertinence. However, tobacco extract usually contains a relatively large proportion of nicotine, and when added in a relatively large amount to cigarettes, it will increase the strength, irritation and roughness of the cigarette. And when the addition amount is small, its fragrance-increasing effect is relatively poor, and the product quality-improving effect is not obvious. Therefore, in t...
