The aim of this study was to determine the effect of three fruit pulp:water ratios (1.0: 2.5, 1.0: 3.5 and 1.0: 4.5) on color, sedimentation, apparent viscosity, and general sensory acceptability in nectar of mamey (Mammea americana L.) Cartagena variety. The mamey was subjected to a precooking at 40 °C to soften the pulp and avoid enzymatic browning; in the standardization stage all the ingredients for a nectar were mixed: CMC (0.07%), citric acid (0.1%), potassium sorbate (0.05%), sugar and fruit. The pasteurization was carried out at 85 °C for 10 minutes, to reduce the microbial load and ensure the safety of the product. The modified Levene test indicated the existence of homogeneity of variances of the parametric variables; the analysis of variance indicated a significant effect of the pulp:water in parameters L * and b * of the color, sedimentation, and apparent viscosity in mamey nectar. The Duncan test determined that at higher pulp:water ratio, lower value for the parametric variables. The test of Friedman indicated that there was no significant difference among the non-parametric samples evaluated (p > 0.05). The best treatment corresponds to the ratio pulp:water of 1.0:2.5.
