Differential scanning calorimetry (DSC) and dynamic mechanical analysis were used to study low moisture (10-50%) gelatinized cornstarch in order to understand the severe embrittlement on ageing often seen in these systems. On ageing at 22°C, gelatinized starch having 11-20% moisture (glass transition temp. (Tg) = 112-30°C) developed endothermic DSC peaks characteristic of enthalpy changes due to s ...
