Metabolomic insights into Monascus-fermented rice products: Implications for monacolin K content and nutritional optimization.

ABSTRACT: This study aims to elucidate the detailed metabolic implications of varying monacolin K levels and sterilization methods on Monascus-fermented rice products (MFRPs), acclaimed for their health benefits and monacolin K content. Advanced metabolite profiling of various MFRP variants was conducted using ultrahigh-performance liquid chromatography coupled with tandem time-of-flight mass spectrometry (UHPLC-Q-TOF MS). Statistical analysis encompassed t-tests, ANOVA, and multivariate techniques including PCA, PLS-DA, and OPLS-DA. Notable variations in metabolites were observed across MFRPs with differing monacolin K levels, particularly in variants such as MR1-S, MR1.5-S, MR2-S, and MR3-S. Among the 524 identified metabolites, significant shifts were noted in organic acids, derivat
