In this work, it was determined, experimentally, the rheological behavior of mango (Keitt) and pineapple (Perola) pulps, whole and centrifuged, in a Haake Rotovisco RV-20 rheometer with parallel plates PQ45, at 30° C. On the rheograms it was adjusted the Mizrahi-Berk (M-B) model, using the shear rate and shear stress. The results were presented as a ratio between the apparent viscosities (whole/centrifuged) with shear rate. This results showed the relative effect of suspended solids on the rheological behavior of each pulp.
