Chemometric Discrimination of Korean and Chinese Kimchi Using Untargeted Metabolomics.

ABSTRACT: Background/Objectives: Kimchi has gained global recognition for its unique taste and health benefits, but its quality is totally different according to its geographical origin of materials and production methods. Methods: In this study, differences between Korean (53 samples) and Chinese kimchi (72 samples) were investigated through comprehensive metabolomic analysis using gas chromatography-mass spectrometry (GC-MS) and ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF MS). Results: Multivariate statistical analyses revealed a clear separation between the two groups. Thirty-four metabolites contributing to the separation were identified. Korean kimchi was enriched in sucrose, quinic acid, sinapic acid derivatives, rutin, c
