The gelatinization characteristics of starches were determined
using differential scanning calorimetry (DSC model 2010, TA Instruments,
New Castle, USA). Starch samples (approximately
2.5 mg, dry basis) were weighed directly in an aluminum pan, and distilled water was added to obtain a starch-water ratio of 1:3 (g/g).The pan was hermetically sealed and allowed to equilibrate for 1 h
before analysis. The sample pans were then heated from 20 to
100 C at a rate of 10 C min1.
