Abstract:
This study elucidated flavor formation in fermented shrimp juice using metagenomics and correlation analyses. The amino acid nitrogen content peaked at 0.54 g/100 mL on the 30th day, surpassing that of traditional fish sauce. Phenolic compounds, including guaiacol and phenylacetaldehyde, were identified as key flavor contributors. The microbial community gradually developed into a stable microbiota dominated by nine genera, including Aspergillus, Lactiplantibacillus, and Meyerozyma. Metagenomic analysis demonstrated that this core microbiome governed critical metabolic pathways for carbohydrate, amino acid, and lipid metabolisms, collectively driving the efficient flavor development in the fermented product.
