Simultaneous and sequential estimation of kinetic parameters in a starch viscosity model.

A modified Brookfield viscometer equipped with a data acquisition system was used to study gelatinizing behavior of native corn starch. Data for the dependent variable (continuous torque), and independent variables were collected. The independent variables were time–temperature history, shear histor...
