摘要：The variations in the secondary metabolite profiles and bioactivities of red raspberry juice during Wickerhamomyces anomalus fermentation remain unknown. Herein, the effects of W. anomalus on the secondary metabolites (phenolic acids, flavonoids, terpenoids, etc.), other selected constituents (total sugars, reducing sugars, and total acids) and bioactivities (antioxidant capacity, α-glucosidase and cholesterol esterase inhibitory activity) of the raspberry juice were assessed. In general, the fermentation decreased the content of total sugars, reducing sugars, total acids and anthocyanins, but increased the content of polyphenols and flavonoids; it significantly enhanced the antioxidant capacity and α-glucosidase inhibitory activity, whereas the cholesterol esterase inhibitory activity was reduced. Moreover, 721 secondary metabolites were identified, wherein 437 secondary metabolites (240 upregulated, 197 downregulated) were selected as differential metabolites via targeted metabolomics. A total of 89 secondary metabolites were annotated in the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, most of which were matched to biosynthesis of secondary metabolites and metabolic pathways. Phenolic acids were mainly synthesized and transformed via phenylalanine metabolism and tyrosine metabolism. ? 2023, The Authors. All rights reserved.
