Abstract

The invention discloses rosemary extract and application thereof in cigarettes and relates to the field of tobacco additives. The tobacco additive is extracted and prepared from Rosmarinus officinalis L. by supercritical CO2 extraction technology and molecular distillation technology. The natural plant extract mainly comprises pinene, cineole, camphene, limonene, linalool, camphor, borneol, terpilenol, bornyl acetate and the like. The extract added into the cigarettes has the effects of increasing fragrance amount and quality, improving fineness, reducing stimulus, covering peculiar odors, and improving comfort.

Description

technical field [0001] The invention belongs to the technical field of tobacco additives, and in particular relates to the preparation of a rosemary extract, and at the same time, the invention also relates to the application of the rosemary extract in tobacco processing. Background technique [0002] In tobacco products, the aroma and taste of tobacco are very important. With the reduction of the tar content of cigarettes in recent years, the smoke flavor of low-tar cigarettes has become lighter and the aroma has weakened. Cigarette products lose their original style and are difficult to be consumed. issues accepted by the reader. Therefore, while reducing the harm and coke of cigarettes, the key issues are to increase the flavor of cigarettes and increase the concentration of smoke. Cigarette flavoring is one of the core technologies of the tobacco industry. Flavoring and adding materials can make up for the lack of fragrance in the cigarette leaf group formula, eliminat...
