A method for preparing cigarette paper with rich cigarette aroma

Abstract

This invention relates to a method for preparing cigarette paper with a rich aroma. The method comprises a blend of flue-cured tobacco leaves, sun-dried tobacco leaves, aromatic tobacco leaves, and Burley tobacco leaves. The blended tobacco leaves are dried at low temperature in an oven, pulverized, and sieved to obtain blended tobacco powder. The blended tobacco powder is extracted with ethanol to obtain extract L1. After passing through an ultrafiltration membrane and removing the ethanol, a tobacco extract L2 is obtained. L2 is mixed with water, allowed to stand overnight, and then centrifuged to obtain an aqueous solution L3 and a precipitate P1. P1 is added to an ethanol solution, stirred evenly, and then dewaxed by freezing. After centrifugation, the ethanol is removed to obtain an alcohol extract L4. L3 is passed through an ultrafiltration membrane to obtain a water-soluble component L5. L4 and L5 are taken in proportion and diluted with ethanol to obtain a coating solution L6. L6 is evenly sprayed onto cigarette paper to obtain cigarette paper with a rich aroma. When burned, the cigarette paper simultaneously produces woody, sweet caramel, and licorice aromas, with a good and abundant fragrance.

Description

Technical Field

[0001] This invention belongs to the tobacco industry, specifically relating to a method for preparing cigarette paper that enriches the aroma of cigarettes. Background Technology

[0002] With the continuous improvement of living standards and the growing awareness of health, reducing harm and tar in cigarettes has become a trend in the tobacco industry. As harmful substances decrease, the aroma components in cigarettes also decrease, which inevitably affects the consumer experience. Adding flavoring to cigarette paper is a common way to compensate for this.

[0003] Invention patent CN111418875A provides a method for preparing cigar-flavored cigarette paper, which effectively enhances the cigar flavor of cigarettes. Invention patent CN114990924B provides a method for preparing cinnabar-smoked glutinous rice-scented cigarette paper, which provides a rich and lasting "glutinous rice" aroma when burned. However, existing flavor-enhancing cigarette papers offer relatively limited aromas, failing to meet consumers' desire for a richer flavor profile. Therefore, providing a cigarette paper that enriches the aroma of cigarettes has become a pressing problem in this field. Summary of the Invention

[0004] The purpose of this invention is to provide a method for preparing cigarette paper with rich cigarette aroma, so as to solve the problems existing in the background art.

[0021] Preferably, in step (8), the ratio of alcohol extract L4 to water-soluble component L5 is 5:3-3:1.

[0022] Preferably, the cigarette paper with rich cigarette aroma contains furfural, furfuryl alcohol, phenylacetaldehyde, solanone, 2-acetylpyrrole and guaiacol, and can produce woody, caramel sweet and licorice aroma when burned.
