The relative crystallinity (% e RC) and X-ray diffraction pattern of native and HMT starches are shown in Fig. 3. The RC of HMT starches ranged from 29.1% to 34.5%. The relative crystallinity (RC) of HMT starch was more than the native starch whereby the extent of the increased RC on HMT was 7.5e12.9% (Fig. 2, data in parenthesis).
