Abstract:
The time-dependent dynamic evolution of flavor profiles in low-salt fermented fish remain poorly understood. This study employed a multi-omics approach (flavoromics, 16S rRNA, lipidomics) to investigate lightly salted tilapia during controlled fermentation. Results revealed a starter-driven microbial succession shifting from early Staphylococcus xylosus dominance to a synergistic co-dominance with Pediococcus pentosaceus. This succession was strongly associated with dynamic lipid metabolism, particularly the accumulation-then-transformation of N-acylethanolamines (NAE) as a highly predictive correlational biomarker. Based on the integrated sensory and flavoromics analyses, the optimal flavor profile was reached at 27 h. Ultimately, a time-resolved conceptual model was proposed where flavor maturation correlated with microbial succession through stage-specific lipid remodeling. This work established a novel theoretical framework for optimizing low-salt fermented fish by demonstrating how a starter culture-driven microbial switch modulated time-resolved lipid metabolism, offering a predictive approach for the precise control of flavor maturation.
