Metabolomics and sensomics reveal non-volatile flavor dynamics in summer-autumn steamed green tea flakes processing.

ABSTRACT: Summer-autumn steamed green tea flakes have attracted attention as a cost-effective extended product of traditional spring shaded Tencha, but their metabolic and sensory transformations during processing remain unexplored. This study employed non-targeted metabolomics and sensomics approaches, including quantitative descriptive analysis, electronic tongue evaluation, and weighted gene co-expression network analysis-to systematically investigate the dynamic non-volatile metabolic transformations and their associations with sensory attributes. A total of 228 metabolites were significantly correlated with sensory traits. Results showed a decline in green characteristics, while seaweed-like notes, umami intensity, and overall preference were enhanced, particularly during the second oven-drying
