Tobacco absolute, preparation method thereof, fuming substrate and tobacco product

Abstract

The invention discloses a preparation method of tobacco absolute. The preparation method comprises the steps of raw material extraction, column chromatography separation, concentrated part screening and product purification. In the processes of raw material extraction, column chromatography separation and concentrated screening, different organic solvents are used for selecting specific aroma substances in tobacco powder, and through the selection, components which do not contribute to the tobacco aroma and tobacco components which can generate irritation during smoking are removed; and the tobacco absolute with rich tobacco fragrance can be obtained. The invention also discloses a fuming substrate and a tobacco product containing the tobacco absolute obtained by the method, and the fuming substrate and the tobacco product can emit rich tobacco fragrance when in use.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a tobacco pure oil and a preparation method thereof, a smoking substrate and a tobacco product. Background technique [0002] Tobacco flavor is an important component of cigarette smoking matrix. The use of flavors and fragrances enriches the flavor of cigarette products, so that the flavor quality of cigarettes can meet the tastes of different consumers. The formation and development of tobacco flavor and fragrance technology research is closely related to the development of the cigarette industry, and plays an important role in promoting the development of the tobacco industry. As a key technology in the development of the tobacco industry, the technology of tobacco flavors and fragrances has been highly valued by cigarette companies and has become an important core technology for the development and expansion of cigarette brands. [0003] Common methods for preparing extract...

AI Technical Summary

Problems solved by technology

In the preparation method, only 95% ethanol is used for eluting in the separation step of the chromatographic column, and it is difficult to separate the aroma-inducing substances in the tobacco components, and the extract will inevitably contain many components and irritants that do not contribute to the aroma. strong ingredients

And in the process of judging whether to collect the eluate, only the subjective judgment methods such as color and aroma are used as the collection basis, which makes it difficult to effectively control the components of the extract and the repeatability of the test is poor.
