Mango is an exotic fruit with great agro-industrial potential and high consumption due to its high nutritional value, bittersweet flavor and pleasant aroma. However, few studies have been conducted on its physical properties used in agroindustrial processes, specifically regarding the rheological behavior of sweetened pulp. The aim of this study was to evaluate the effect of temperature (10-50 °C) and sucrose concentration (0-25%) in the rheological properties of the sweetened pulp of hilacha mango (Mangifera indica L. cv. Magdalena river). The power law showed the best adjustment to the rheological behavior with high determination coefficient values (R2=0,997). Sweetened mango pulp exhibited a pseudoplastic behavior when exposed to shear thinning (n<1). The consistency coefficient was found to be dependent on the temperature and concentration of soluble solids described by the Arrhenius relationship and an exponential model, respectively.
