This study prepared buckwheat dietary fiber with improved biological activity through liquid fermentation and found that fermented buckwheat dietary fiber had potential prebiotic effects in ameliorating obesity, as well as reducing hepatic lipid profile, oxidative stress, and regulating gut microbiota.
Tartary buckwheat is a popular natural grain commonly used as a functional food in various countries. This study aimed to prepare buckwheat dietary fiber with improved biological activity using liquid fermentation of Aspergillus niger and to elucidate its physicochemical properties and related mechanisms. Compared with un-fermented buckwheat dietary fiber, Aspergillus niger fermentation increased the soluble dietary fiber content, thereby improving dietary fiber's physical and chemical properties such as water, oil retention capacity, and swelling cholesterol-binding capacity. Fermented Tartary buckwheat dietary fiber treatment for 14 weeks significantly decreased the hepatic lipid profile, oxidative stress, and protein expression in mice. In addition, fermented Tartary buckwheat dietary fiber intervention could regulate high-fat diet-induced disorders of gut microbiota. These results suggested that fermented Tartary buckwheat dietary fiber has potential prebiotic effects in ameliorating obesity.
