Deshidratación Osmótica de Láminas de Mango cv. Tommy Atkins Aplicando Metodología de Superficies de Respuesta Osmotic Dehydration of Mango Pieces cv. Tommy Atkins Applying Response Surface Methodology

Abstract

RESUMEN: Se aplicó el método de superficies de respuesta para estudiar el efecto de la temperatura y la concentración de ácido cítrico sobre la deshidratación osmótica de láminas de mango cv. Tommy Atkins. La deshidratación osmótica se evaluó en términos del porcentaje de pérdida de peso (%PP), ganancia de sólidos (%GS), pérdida de humedad (%PH), y pérdida de actividad acuosa (%PAw). Los resultados indicaron que tanto la temperatura como la concentración de ácido cítrico, tuvieron efectos significativos sobre el %PP, %PH, y %PAw, en el rango de condiciones evaluado (25 ºC – 45 ºC) y (1% - 3%) respectivamente. La adición de ácido cítrico en la solución osmodeshidratante redujo de forma significativa los recuentos de microorganismos, sin afectar las características sensoriales del producto. Los niveles máximos de los parámetros cinéticos se consiguen después de 4 h de proceso, con temperaturas de 45 ºC y concentraciones de ácido cítrico de 3% p/p, siendo 47,62%, 53,07% y 6,04%, los valores óptimos para %PP, %PH y %PAw respectivamente, con aceptación sensorial del 100 % y reducciones en los recuentos microbianos de más de dos ciclos logarítmicos.

ABSTRACT: The response surface methodology was applied to study the effect of temperature and concentration of citric acid in osmotic dehydration of cv. Tommy Atkins mango pieces. Osmotic dehydration was evaluated in terms of the percentage of weight reduction (%WR), solid gain (%SG), water loss (%WL) and reduction of water activity (%RWA). The results indicated that the temperature and the concentration of citric acid had significant effects on the (%WR), (%WL) and (%RWA) in the range of conditions evaluated (25 °C– 45 ºC) and (1% - 3%) respectively. The addition of citric acid in the osmodehydrating solution significantly reduced the microorganism recount without affecting the sensory characteristics of the product. The maximum values of kinetic parameter are reached after 4 h of processing, with temperature of 45 ºC and concentration of 3%. The optimum values for %WR, %WL y %RWA, were 47.62%, 53.7% y 6.04%, respectively. The sensory acceptance was of 100% and reductions in the microbial recount of more than two logarithmic cycles.
