My current research focuses on comparing the physicochemical properties of organic and conventional starches from various plant sources in terms of their thermal and rheological behaviors. The properties of interest are the gelatinization temperature range and retrogradation rates analyzed by the Differential Scanning Calorimetry (DSC), the time-, temperature-, and shear-dependence analyzed using a Rheometer, as well as the amylose and amylopectin content. The results will have significance in determining the processing conditions in organic food production experiencing ingredient transition from the conventional to the organic form.
