ResumenSe estudió la cinética de transferencia de masa durante la deshidratación osmótica de mango (Mangifera indica L.) var. Tomy Atkins en láminas. Se utilizó una relación jarabe/fruta de 3/1 durante 6 h de proceso. Se compararon tres modelos matemáticos para describir la cinética de pérdida de agua y ganancia de sólidos a diferentes temperaturas (20, 35 y 50 ºC) y concentraciones de sacarosa (45-60 °Bx). Se ajustó el modelo empírico de Azuara, un modelo fenomenológico a partir de la solución de la segunda ley de Fick y el modelo empírico de Peleg. Los resultados indicaron que el modelo de Peleg ajustó mejor que el modelo empírico de Azuara y que el modelo fenomenológico derivado de la ley de Fick. Adicionalmente se hizo un ajuste tipo Arrhenius para los coeficientes de difusión efectiva a 60 °Bx, en función de la temperatura.

Tommy Atkins as Function of the Temperature AbstractThe kinetics of the mass transfer process during the osmotic dehydration of mango sheets (Mangifera indica L.) var. Tomy Atkins was studied. The syrup/fruit ratio was 3/1 during the six hour process. Three mathematical models to describe the kinetics of water loss and solid gain at different temperatures (20, 35 and 50 °C) and sucrose concentrations (45 and 60 %) were used compared to each other. The empirical model of Azuara, a phenomenological model from solution of Fick's second law, and Peleg's empiric model were used. The results shown that empirical model of Peleg gave more accurate results than the empirical model of Azuara and the phenomenological model from solution of Fick's second law. Additionally, an Arrhenius equation for the effective diffusion coefficient as a function of the temperature function (for 60 °Bx concentration) was fitted
