Abstract: Konjac glucomannan (KM) is a water soluble glucomannan with high molar mass. KM aqueous solution shows extremely high viscosity. KM can be depolymerized by γ-rays irradiation. The molar mass of original KM was 1020 kDa. The molar mass of irradiated KM decreased significantly with increase of absorbed dose up to 2 kGy and then decreased gradually. The molar mass of 10 kGy irradiated KM was 236 kDa. The radius of gyration (R G ) of original KM was 98.0 nm. The R G value decreased significantly with increase of t… Show more
