Problems solved by technology

At present, the traditional method is to extract the tobacco raw material with a polar solvent and concentrate it into a paste, or to extract the water extract through alcohol precipitation and then take the clear liquid to concentrate to obtain a tobacco paste. The relative content of the aromatizing ingredients contained in the tobacco is not high, the solvent consumption is large and there are problems such as residues, which cannot meet the needs of the further development of the tobacco industry

Embodiment 1

[0013] Weigh 200g of pieces of tobacco leaf (C2F) into a container, add 2000g of 70% ethanol, then add 1g of phosphoric acid, heat with an electric heating mantle and extract at 90°C for 2 hours. The obtained product was filtered and cooled to 20° C., left to stand for 1 hour, and the supernatant was concentrated under reduced pressure to a paste. The relative density of the paste was 1.258, and 110 g of tobacco extract was obtained.

[0014] Tobacco extract was added to tobacco leaves (X3F) at a mass ratio of 0.1%, and the sensory evaluation results are shown in Table 1.

Embodiment 2

[0016] Weigh 1000g of pieces of tobacco leaf (C2F) into a round bottom flask, add 7000g of 90% ethanol, then add 15g of sulfuric acid, heat with an electric heating mantle and extract at 80°C for 1 hour. The obtained product was filtered and then cooled to 25°C, left to stand for 1.5 hours, and the supernatant was concentrated under reduced pressure to a paste with a relative density of 1.245 to obtain 548 g of tobacco extract.

[0017] Tobacco extract was added to tobacco leaves (X3F) at a mass ratio of 0.07%, and the sensory evaluation results are shown in Table 1.

Embodiment 3

[0019] Weigh 2000g of pieces of tobacco leaf (C2F) into a container, add 10000g of 95% ethanol, and then add 60g of phosphoric acid, heat with an electric heating mantle and extract at 60°C for 3 hours. The obtained product was filtered and cooled to 28°C, and left to stand for 2 hours. The supernatant was concentrated under reduced pressure to a paste. The relative density of the paste was 1.255, and 1162 g of tobacco extract was obtained.

[0020] Tobacco extract was added to tobacco leaves (X3F) at a mass ratio of 0.05%, and the sensory evaluation results are shown in Table 1.

Abstract

The invention relates to a preparation method of tobacco extract and application of the tobacco extract in cigarettes. The preparation method includes: weighing tobacco material, adding 70-95% ethanol according to the material-liquid mass ratio of 1:5-1:10, adding phosphoric acid or sulfuric acid accounting for 0.5-3% of the tobacco material by weight, performing heat reflux extraction for 1-3 hours at the temperature of 60-90 DEG C, filtering the product, allowing for cooling and clarifying, and subjecting supernate to reduced pressure compression to obtain extract, namely herbal extract; adding the tobacco extract, accounting for 0.05-0.1% of a tobacco leaf set by weight, to the tobacco leaf set. The tobacco extract made by the method is natural and safe, has the significant effect of making tobacco products more fragrant and less irritating, and has high application value. The preparation method is simple and easy, and the technical process is highly repeatable.

Description

technical field [0001] The invention relates to the technical field of preparation and application of tobacco extract. Background technique [0002] In recent years, with the promotion of the level of cigarettes, reducing the tar release of cigarettes, the lack of taste of tobacco and the weakening of satisfaction are problems that the tobacco industry needs to solve urgently. [0003] Tobacco extract is a dark brown viscous paste, which can be used in tobacco essence to increase the natural aroma of tobacco and improve the smoking quality of tobacco. At present, the traditional method is to extract the tobacco raw material with a polar solvent and concentrate it into a paste, or to extract the water extract through alcohol precipitation and then take the clear liquid to concentrate to obtain a tobacco paste. The relative content of the aromatizing components contained in the tobacco is not high, the solvent consumption is large and there are problems such as residues, whic...
