description Shaping, a critical step in green tea manufacturing, profoundly influences the quality of green tea, yet its effects on non-volatile metabolites remain underexplored. This study evaluated how different shaping techniques influence green tea quality and identified key metabolites governing sensory attributes. A multi-platform approach integrating E-tongue, colorimetric analysis, and untargeted metabolomics was employed. Sensory evaluation indicated that flat green tea technique could attain superior overall quality. A total of 115 non-volatile metabolites encompassing 10 distinct categories were identified, with flavonol and flavonol/flavone glycosides (30.4 %) and amino acids and derivatives (25.20 %) being the predominant categories. Moreover, 48 non-volatile metabolites were recognized as pivotal differential metabolites under four shaping techniques based on VIP > 1and p < 0.05. Correlation analysis indicated that l-leucine and strictinin positively correlated with the bitterness of tea infusion whereas theobromine exhibited a negative correlation with the sweetness. These findings bridge empirical tea-processing practices with metabolomic evidence, offering actionable strategies for precision manufacturing of shape-specific green teas with enhanced sensory appeal.
