摘要： Fermented golden pompano ( Trachinotus ovatus) ) has a distinctive flavor, but the key flavor compounds and aroma profiles remains unclear. Thus, a molecular sensory science approach was used to investigate flavor and key aromatic compounds. The fermentation process enhanced the overall flavor, as evidenced by sensory evaluation and electronic nose (E-nose) analyses. A total of 48 aroma compounds were identified at different fermentation stages. Among them, 11 key aroma compounds were identified by flavor dilution (FD) factors >= 8 and odor activity values (OAVs) >= 1. Aroma recombination model successfully reproduces the characteristic floral and fruity aromas of fermented golden pompano. Omission experiments identified hexanal, decanal, 1octen-3-ol, limonene, and isovaleric acid as significant contributors to the overall aroma profile. This study elucidates flavor dynamic modulation and key aromatic compounds during golden pompano fermentation, to provide a theoretical reference for the targeting process regulation of the product.
