A total 11 Korean rice cultivar was prepared and investigated for its starch and quality characteristics. Amylose content, damaged starch contnent, water contnent, water absorption index (WAI), water solubility index (WSI), particle size and pasting properties of rice flours were measured. The amylose content of waxy, middle waxy and non waxy type domestic normal rice cultivars were 7.09%, 11.69% and 18.58-21.52%, respectively. Moisture content of 11 Korean rice cultivar were 7.19-13.89%. WAI and WSI did not show variations by amylose contents. Sample with high moisture contents was lower damaged starch contents. Particle size of samples was 27.61-189.67 µm. Final viscosity and pasting temperature of the samples was shown to rage from 45.54 to 313.94 RVA and from 71.03 to 87.98℃, respectively. In this study, results indicated that samples with low moisture contents tend to shown low particle size and high damaged starch contents regardless waxy, middle-waxy, and non waxy type.
