Cereals are known as one of dietary fibers sources. These compounds are not fully digested in human body, and they have strong binding capacity for toxic agents. Thus, dietary fibers have been indicated having ability for decreasing the residue of heavy metals in the body. Heavy metals such as cadmium (Cd) are widely found in natural environments and can be accumulated in the food chain. People can be exposed to cadmium primarily through contaminated foods. In this study, various cereals including mung bean (Vigna radiate (L.) Wilczek), red rice (Oryza sativa L.), black soybean (Glycine soja), and black glutinous rice (Oryza sativa L. Forma Glutinosa) were assessed their ability on binding with Cd in vitro. Concentration and particle size of cereals were used as independent variables. The result demonstrated that the higher concentration of cereals resulted in the higher cadmium adsorption. In mung bean and black soybean samples, the bigger the particle size, the higher the higher cadmium adsorption. On the other hand, in red rice and black glutinous rice samples, the smaller the particle size, the higher cadmium adsorption. The higher cadmium adsorptions were found in insoluble fractions of cereals. Each cereal also showed different ability on binding cadmium. Black soybean and black glutinous rice showed the highest binding ability among other cereals, which about 60 – 99 µg and 69 – 97% respectively.
