Objective To explore the rheological characteristics of the film-forming solutions made from potato starch. Methods Discovery HR-2 rheometer was used to determine the effects of different amounts of potato starch, time of potato starch gelatinization, and storage time on the static and dynamical rheological properties of the film-forming solu? tions. Results The results showed that the film-forming solution was a pseudoplastic non-Newtonian fluid, and the rheo? logical characteristics could be fitted by Ostwald-de-Waele model. Meanwhile, the changes of the flow behavior index and consistency coefficient were affected by the amounts of potato starch, time of potato starch gelatinization, and storage time. During the dynamic oscillatory experiments all the film-forming solutions showed a gel-like behavior in the low-frequency range, with the storage modulus G′larger than the loss modulus G″. Conclusion The rheological characteristics of film-forming solutions have very important theoretical and practical significance for the processing of films.
