Another parameter obtained from application of the Power Law model was the flow behavior index, which indicates the degree of pseudoplasticity or the dilatant character of a fluid. The flow behavior index (n) ranged from 0.55 to 0.64 (n ¼ 1), indicating that all ice cream samples behaved as pseudoplastic fluids (Table 3).the rheological properties of ice cream are described as pseudoplastic. For the ice cream submitted to enzymatic treatment, there was an increase in the pseudoplastic properties as the flow behavior index approachedzero. This behavior was also evidenced by with the cross-linking of whey proteins through the action of TG. The favoring of a pseudoplastic behavior probably occurred due to higher-molecular-weight polymers formed during the cross-linking reaction promoted by the TG. Innocente, Comparin, and Corradini (2002) affirmed that with an increase in the shear rate, large polymer molecules tend to disentangle and possibly align in the flow field, offering less resistance to flow.
