Agarwood leaf-based wood flavor flavor for tobacco and its preparation method and application

Abstract

The invention provides a method for preparing spice of costustoot flavored cigarettes based on aquilaria leaves. The method comprises the following steps: crushing and screening aquilaria leaves; performing enzyme treatment; performing heat reflux extraction; carrying out solid-liquid separation; concentrating at reduced pressure; performing supercritical CO2 extraction; reclaiming an entrained solvent; carrying out membrane separation, sectioning and dicing; and preparing to obtain the novel spice of the costustoot flavored cigarette based on aquilaria leaves. The spice has the characteristics that the aquilaria leaves with rich resources are used as a raw material, are subjected to wall-breaking treatment by using an enzyme method and are treated by heat reflux extraction to obtain an extract; aquilaria leaf essential oil is extracted from the extract by using a supercritical extraction process, and the extraction yield can be remarkably increased by virtue of the combined process; the aquilaria leaf essential oil is sectioned and diced by using membrane separation, and is mixed with guaiacol, santalol, cedar camphor, vetiver oil, ethanol and propylene glycol in a certain proportion; the prepared spice is added into cigarettes in a certain weight proportion. Therefore, the cigarettes are mellow and rich in flavor, the fragrance is improved, an elegant costustoot flavor is given to the cigarettes, and the sensing quality of the cigarettes can be remarkably improved.
