Physicochemical properties, antioxidant activities and hypoglycemic effects of soluble dietary fibers purified from Lentinula edodes

Lentinula edodes (L. edodes), which imparts various health benefits to humans, is considered a novel source of soluble dietary fiber (SDF). In this study, ultrasonic-assisted hot-water method was used extract SDF (U-SDF) from L. edodes, and physicochemical, antioxidant hypoglycemic properties the U-SDF were investigated. Physicochemical showed that water solubility, holding capacity, swelling oil capacity higher than extracted using hot without ultrasonication. The DPPH, •OH, •O2- radical clearance rates indicated exhibited better activities. also notable α-amylase α-glucosidase inhibition Treatment with alleviated glucose peroxidation metabolism disorders in vivo. Histological analysis improved oxidative tissue damage diabetic mice. These results provided theoretical basis for development utilization derived edodes.
