Overview

This study demonstrates differences in metabolomics and sensory properties between fu brick tea and fu loose tea, indicating pressing process effects on quality.

Key Points

  • Fu loose tea displays a stronger aroma and mellower taste than fu brick tea, impacting consumer preference.
  • The quantity of Eurotium cristatum was 56.7% higher in fu loose tea compared to fu brick tea, reflecting significant biochemical diversity.
  • Twelve differential metabolites were identified through metabolomics, highlighting unique compounds between the tea types.
  • Gallic acid, catechin, and epicatechin were found at much higher levels in fu loose tea, serving as key markers for distinction.
