Method for enriching burnt-sweet aroma note in yunnan flue-cured tobacco and aerosol-forming material

Abstract

A method for enriching a burnt-sweet aroma note in Yunnan flue-cured tobacco includes: S1: diluting a Yunnan flue-cured tobacco extract with a diluent to obtain an obtained diluted solution; S2: subjecting the obtained diluted solution to an elution treatment using a C18 column under a pressure of 5-20 bar, the elution treatment including: first performing a primary elution with a first eluent, then performing a secondary elution with a second eluent, and collecting a secondary elution solution as a collected secondary elution solution, the first eluent including water or an aqueous ethanol solution with a mass concentration of less than 10%, and the second eluent including an aqueous ethanol solution with a mass concentration of 38-42%; and S3: concentrating the collected secondary elution solution to obtain a sample with the burnt-sweet aroma note.
