From: Antiobesity effect and metabolite analysis of catechin functional kimchi
Partial least squares discriminant analysis (PLS-DA) score plot of kimchi metabolites (A) and its quality parameters (B). Metabolites were analyzed using ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC–Q-TOF MS). The statistical acceptability of the PLS-DA model was evaluated by R2X, R2Y, Q2, and p value and validated by cross validation with a permutation test.
