Rheological Properties of Waxy Maize Starch Pastes

摘要：

The pastes of the waxy maize starch were prepared based on different ratios between starch and water. The rheological properties of the waxy maize starch pastes were researched by rotational viscometer, and the rheological models of the starch pastes were concluded, the fluid models were validated. The results showed that the shear stress of the waxy maize starch pastes is increased as the sheer rate is increased and the shear stress is increased with the increase of the ratio of starch with water under the identical sheer rate. The rheological properties data of the waxy maize starch pastes were regressed by nonlinear regression method and their rheological models were established. The waxy maize starch pastes belong to a yield-pseudoplastic fluid, the rheological properties of the starch pastes are characterized by yield pseudoplastic model. The research on the rheological properties and fluid models of waxy maize starch pastes will provide theoretical foundation for development and application of waxy maize starch.
