Resumen

Se estudió la variación de la conductividad térmica de jugos concentrados de mandarina, limón y naranja en un rango de concentraciones entre 12 a 65ºBrix, y a tres temperaturas, 283, 293 y 303 K. La conductividad térmica fue determinada mediante un medidor de conductividad térmica, marca Decagon Devices Incorporation modelo KD2. Para los tres jugos concentrados los valores de conductividad térmica obtenidos presentan diferencias estadísticamente significativas (en un nivel de 95 %) con la concentración, para el rango de concentraciones en estudio. La conductividad térmica no presenta diferencias estadísticamente significativas con la temperatura (para un nivel del 95 %) en el rango de temperatura estudiado. Los datos se ajustaron a diferentes modelos matemáticos. Los valores promedios para la conductividad térmica en el rango de temperaturas y concentraciones en estudio, variaron entre 0.3 y 0.6 (W m–1K–1).
