Outline of Final Research Achievements |
Starch is the major component of the rice flour, and utilization of the rice flour is mainly affected by the characteristics of the starch. By controlling the water absorption of the rice flour, gelatinization of starch can be controlled, and improvement of the cooking quality of the rice flour is enabled. Enzyme, heat, and alkali treatments were employed to alter the water absorption of the rice flour. Combination of pullulanase treatment and annealing of the starch lead to the reduction of water absorption of the rice flour. Although starch crystallinity is highly correlated with the water absorption capacity, the absorption rate can be separately controlled. Therefore, these procedures can be used to improve the usage of the rice flour, which can lead to the development of novel utilizations.
