Abstract

Thermal and rheological properties of physically modified wheat, potato and pea starches were determined in comparison to those of the native ones. The enthalpy value of a pea starch preparation was higher compared to that of the native pea starch. Storage and loss moduli of 10% gels from native starches were higher than the values obtained for modified starches. The rheological properties of non-yeasted wheat doughs were changed under supplementation (10%) with modified starch preparations. Compared to the control sample, an increase in storage and loss moduli was noticed at temperatures from 30 °C to 60 °C, whilst at temperatures up to 90 °C, the values of both moduli were found to decrease.
