3.3. Properties of rice flours
The amylose content of rice starch isolated from Hopyung rice was 16.46 1.54 g/100 g. Hopyung rice was deemed to be from low amylose rice cultivars as classified by the International Rice Research Institute (IRRI, Manila, Philippines). Particle size and damaged starch are two factors affecting the properties and application of flour. The damaged starch of rice flour was increased with decreasing particle size of flour (Table 1).
