Revealing the dynamic changes in the metabolites and sensory quality of Citri Reticulatae Pericarpium during aging using feature-based molecular networks and metabolomics.

ABSTRACT: The contribution of non-volatile metabolites to the unique flavor formation in Citri Reticulatae Pericarpium (CRP) during aging remains poorly characterized. This study employed sensory evaluation, electronic tongue (E-tongue) assessment, untargeted metabolomics in conjunction with feature-based molecular networks (FBMN) to elucidate flavor differentials and metabolic mechanisms during the aging process of CRP. The results showed that extended aging time enhanced the bitterness, astringency, aftertaste-bitterness, aftertaste-astringency, and sweetness of the CRP. FBMN tool used for the first time to annotate flavonoid components of CRP. Multivariate statistical analyses revealed that of the total 1092 identified metabolites, 189 differed significantly during aging. Combined with the result
