Summary Starch, protein and lipids are the main rice grain components that affect cooking and eating quality. An analysis of the literature indicates that rice of good eating quality shows the following characteristics: low amylose and low protein contents and large breakdown as measured by an amylograph. However, there are significant cultural differences in quality preferences and the most important acceptance factors for Asian consumers living in the United States are cooked rice appearance and aroma. This review examines the major constituents of rice (starch, lipid and protein) and their impact on eating quality as reflected by the functional properties of rice.
