Abstract
Chinese yam (Dioscorea opposita Thunb.), as one of the medicinal and edible homologous plants, is rich in various nutrients and functional factors. In this study, Chinese yam fermented by Saccharomyces boulardii was performed to investigate its bioactive components and metabolic profile. And then, the main bioactive components and biological activities of fermented Chinese yam ethanol extract (FCYE) were evaluated. Results showed that there were 49 up-regulated metabolites and 52 down-regulated metabolites in fermented Chinese yam compared to unfermented Chinese yam. Besides, corresponding metabolic pathways analysis initially revealed that the distribution of bioactive substances was concentrated on alcohol-soluble small molecular substances. Ulteriorly, the total polyphenol content and the total flavonoid content in FCYE were significantly increased, and the corresponding antioxidant and immunomodulatory activities in vitro were also significantly enhanced. Our study provided a new reference for the comprehensive utilization of Chinese yam and laid a theoretical foundation for the development and application of natural probiotic-fermented products.
期刊介绍:
Food Science and Human Wellness is an international peer-reviewed journal that provides a forum for the dissemination of the latest scientific results in food science, nutriology, immunology and cross-field research. Articles must present information that is novel, has high impact and interest, and is of high scientific quality. By their effort, it has been developed to promote the public awareness on diet, advocate healthy diet, reduce the harm caused by unreasonable dietary habit, and directs healthy food development for food industrial producers.
