Rice pollution by cadmium in China is becoming a crucial problem in food safety. It is of great importance for the future design of cadmium-removal strategy by studying the binding behaviors of cadmium to different fractions of rice proteins (RPs). In this study, the thermodynamics and kinetics involved in the bindings of cadmium to four different RP fractions, i.e., glutelin, prolamin, globulin and enzyme-extracted proteins, were investigated. The results showed that cadmium was readily bound to each fraction of RPs, and the equilibrium was attained within 30 min. Of all the protein fractions, prolamin obtained the highest binding capacity with …
