The thermal parameters of native, HMT-20 and HMT-30 starches determined by DSC are summarized in Table 3. Native mung bean starch had an endothermic transition ranging from 67.0 _C to 76.2 _C with enthalpy of 5.1 J/g (dry sample). Results clearly show that HMT starch had an endothermic transition over a range of approximately 75.6 _Ce99.5 _C, with an increase of onset melting temperature of HMT starch about 9 _C. The increase in melting
enthalpy for HMT starches were about 11.1e17.0 J/g than in native starch. These results indicate that HMT starch showed more heat stability than that of native starch.
