The objective of this work was the sensorial evaluation of mapará meat, in natura and without osmotic pre-treatment before drying. For the acceptability test of the mapará fish muscle bisquit, the in natura fish samples were used and dried under optimum osmotic dehydration conditions, in solutions of NaCl, NaCl + sucrose and in solution of NaCl + corn syrup solution before drying. 25 not trained testers were used, of both sex, ages ranging from 20 to 60 years. The evaluated sensorial attributes of the samples were appearance, aroma, flavor, texture and overall impression. The aroma and texture of the samples with and without osmotic pre-treatment were the ones most widely accepted by the consumers. It is concluded that the samples treated with osmotic solutions, with the exception of those processed with NaCl + corn syrup solution, provided products with better texture, flavor and a more pleasant aroma.

Osmotic dehydration of mapará fillets has been used as a pre-treatment before dehydration and refrigeration of food as a means of reducing product moisture content. The aim of this study was to optimize mass transfer occurring during osmotic dehydration of mapará using the response surface methodology. Osmotic dehydration was carried out following a 23 complete factorial design, with eight factorial, three central and six axial points, totalizing 17 assays, where the values of the dependent variables, weight loss (PP), water loss (PA), solid gain (GS), GS/PA and tiobarbituric acid (TBA), are a function of the independent variables, temperature, concentration of NaCl and immersion time. The statistic analysis, applied to the experimental data was carried out using the pure error and the residual SS. Applying the response surface methodology, the best condition of convergence of lower weight loss, greater water loss and lower salt gain corresponded to a sodium chloride concentration of 22%, temperature of 46 °C and time of 7 hours.
