Physicochemical properties of starch in relation to rheological properties of wheat dough (Triticum aestivum L.)

In this study, the micro-structure and physiochemical properties of starch from six wheat varieties (lines) with different dough properties were investigated, and the rheological properties of wheat dough were determined. Six varieties with significant different starch properties perform various dough behaviors, among which Xinmai 26 with preeminent dough quality has the highest amylose content, B-type starch granule content, short-range ordered degree and starch swelling power but lowest relative crystallinity and gelatinization enthalpy of starch. The findings indicate that starch physicochemical properties also influence the dough behaviors and provide helpful information for demonstrating the effects of starch on dough properties in the protein-starch matrix.
