摘要: Abstract Monascus mold produces useful bioactive compounds such as pigments, monacolin K, and ergosterol. In this study, metabolomics analysis was used to investigate the metabolic profile changes in aurantiacus Li AS3.4384 (MALA) induced by genistein at different fermentation times using UHPLC-Q-TOF-MS/MS. The addition of found not only reduce citrinin but also suppress significant differential metabolites. A total 21 metabolites were involved most pathways (impact >0.1). These affected aspartic acid, glutamic acid pathway, tricarboxylic (TCA) cycle, pyruvate synthesis lysine degradation pathway. Thus, may change precursor for Monascus. findings provide insight into will help improve quality control safety food supplements.
