Abstract: The present work has evaluated the dynamic and steady-state shear rheological properties of siriguela (Spondias purpurea) pulp as function of temperature (0-80 degrees C), as well as the applicability of the Cox-Merz rule. The product flow behavior could be well described by the Herschel-Bulkley's model (R(2) > 0.98), whose parameters were modeled as function of temperature (R(2) > 0.91). The product has shown a weak gel behavior, with storage modulus higher than loss modulus in the evaluated frequency range. The storage and loss modules could be well described by a power function of the oscillatory frequency (R(2) > 0.93), whose parameters were modeled as function of temperature (R(2) > 0.97). Moreover, a power modified Cox-Merz rule could describe the rheological properties of S. purpurea pulp (R(2) > 0.96). The obtained data are potentially useful for future studies on food properties and process design. (C) 2011 Elsevier Ltd. All rights reserved.
