Study on Functional Properties of Physically Modified Dietary Fibres Derived from Defatted Rice Bran

Abstract

In this study, we investigated the predictive indices for hypoglycemic effect of physically modified fibers. Micronization, ultrasonic, microwave and extrusion cooking treatments were applied to defatted rice bran dietary fibers to get modified defatted rice bran dietary fiber. The effects of physical treatments, pH and time of digestion, on the water binding Capacity (WBC), Swelling Capacity (SWC), Cation exchange Capacity (CEC) and Glucose retardation capacity (GDRI) were studied. All modified fibers exhibited significance (p
