Abstract
|
|
|
|
Gelatinization temperatures of upland and Lowland waxy brown rice starches annealed at 25°and 60℃ for 24hr were investigated with differential scanning calorimetry. No annealing effect was observed at low temperature. The upland rice starch showed narrower range of gelatinization temperature upon annealing treatment at 60℃ compared with the lowland rice starch. The enthalpy of gelatinization was not changed in case of the upland rice starch but was increased in case of the lowland one upon annealing.
