CINÉTICA DE DEGRADACIÓN DE VITAMINA C Y COLOR DE PULPA DE PITAHAYA (Hylocereaus monacanthus) PASTEURIZADA

Palabras clave: Vitamina C, Luminosidad, Cinética de degradación, Primer Orden, Arrhenius

Resumen

El objetivo de la investigación fue evaluar la cinética de degradación de vitamina C y Color (Luminosidad) en la pulpa de pitahaya (Hylocereaus monacanthus), a temperaturas de 75, 80, 85, 90° C.  La temperatura y tiempo tienen efecto significativo (al 95% de confiabilidad) sobre las variables dependientes, afectando negativamente. Tanto la degradación del ácido ascórbico como la degradación de los parámetros de color (luminosidad) fueron bien descritas por modelos cinéticos de primer orden y la dependencia de la temperatura fue satisfactoriamente representada por la ley de Arrhenius.
