Abstract: In order to study the variation of robust flavor style tobacco extract during pyrolysis process, B011 tobacco from Henan was used as the raw material and tobacco extract was prepared by using ethanol-water solution as the extraction solvent. After freeze drying, the extract was subjected to microwave pyrolysis, the pyrolysis products were analyzed and added into an electronic cigarette for sensory evaluation. The results were obtained using a microwave power at 900 W and pyrolysis time at 120 s. The results showed that:1) the total amount and total mass of aroma components in the pyrolysis products were larger; 2) the amount and mass of each volatile aroma component in the pyrolysis products were larger; 3) the average RSD of peak areas of five replicate tests was 2.52%; 4) the results of sensory evaluation indicated that the sensory quality of electronic cigarette containing pyrolysis products was better.
