Abstract

Dietary fiber (DF) from corn sprouts, subjected to pretreatment with static magnetic field (SMF), was systematically investigated for its structural and functional characteristics using an enzymatic method. After SMF treatment, the surface of soluble DF showed higher pore density and pore structures, and insoluble DF showed more folds and a concave-convex surface profile. FT-IR and thermogravimetric analyses also showed that SMF pretreatment improved the functional group structure and thermal stability of DFs in corn sprouts. Moreover, SMF pretreatment improved the inhibitory effects on α-amylase and α-glucosidase activities, as well as increased water holding, oil holding, and water swelling capacities. Compared to the untreated corn sprouts, the DF obtained from SMF treatment exhibited stronger antioxidant activity. In summary, these findings suggest that SMF pretreatment enhances the physicochemical and functional properties of DF derived from corn sprouts. It suggests that SMF can serve as a prospective technique for corn sprouts products processing.
