Abstract

Pyrolysis behavior of sucrose esters (SEs) significantly impacts the aroma and quality of cigarettes. However, there is limited research on SEs and their pyrolysis in Flue-cured tobacco. In this study, nine SEs and their three pyrolysis products, glucose esters (GEs), were identified using LC-MSⁿ, with six esters being reported in Flue-cured tobacco for the first time. The aging and baking processes of tobacco leaves promoted the pyrolysis of most SEs along with the formation of GEs. During long-term storage at 4 ℃, tobacco SE was found to undergo 3-methylvaleryl intramolecular migration from glucose to fructose as well as intermolecular elimination and addition reaction of acetyl groups, greatly enriching the types of tobacco SEs. By comparing different storage temperatures, this acyl migration demonstrated a temperature dependence. Under simulated cigarette smoking conditions via thermal microwave plasma treatment, SE was rapidly degraded into GE intermediates, fatty acids, furfural, and other aroma compounds. These insights advance our understanding of SE pyrolysis and aroma development, and provide potential explanations for the structural diversity of tobacco SEs.

期刊介绍： The Journal of Analytical and Applied Pyrolysis (JAAP) is devoted to the publication of papers dealing with innovative applications of pyrolysis processes, the characterization of products related to pyrolysis reactions, and investigations of reaction mechanism. To be considered by JAAP, a manuscript should present significant progress in these topics. The novelty must be satisfactorily argued in the cover letter. A manuscript with a cover letter to the editor not addressing the novelty is likely to be rejected without review.
