Hot pot is popular among consumers because it provides a rich and multi-level flavor experience during boiling. In this study, the aroma compounds of hot pot seasoning (HPS) during different boiling times were characterized by comprehensive two-dimensional gas chromatog.-olfactometry-mass spectrometry. Twenty-four aroma-active compounds with high flavor dilution (FD) factors were selected by aroma extract dilution anal. Based on the odor activity values (OAVs), 23 key aroma-active compounds were identified as characterizing the main aroma profile of HPS during boiling. Furthermore, multivariate statistical anal. was used to screen out 10 key differential aroma-active compounds, which were used to distinguish the difference in aromas for HPS during the different boiling times. Finally, kinetic fitting was used to reveal the generation regularity of these 10 compounds The results showed significant changes in the content of acetophenone, (E)- 2-heptenal and phenylacetaldehyde, conforming to first-order kinetics during boiling. However, other compounds were not well-fitted into the classical reaction kinetics models.
