ABSTRACT. The digestibility and Glycemic Index (GI) of rice starch are partly attributable to the inherent properties of starch. In this study, the composition of rice with respect to moisture content, resistant starch (RS), total carbohydrate, dietary fiber, protein content, ash content and glycemic indices of three popular rice varieties, Bg 300, Bg 358 and At 405 were examined under two processing conditions (raw, parboiled) and three cooking methods (rice cooker method, boiling and straining method and conventional cooking method). The RS content of variety At 405 (7.50 ± 0.37 %) was significantly higher (p
