From: Anticancer effects of washed-dehydrated solar salt doenjang and its metabolites
Partial least squares discriminant analysis (PLS-DA) score plots of doenjang 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 (A) was evaluated by R2X, R2Y, Q2, and p-value and validated by cross validation with a permutation test (B)
