Resumen


En presente estudio se determinaron los parámetros cinéticosde aceites de argán comestible (prensado en frío a partir de granos tostados de argán) y cosmético (prensado en frío a partir de granos de argán sin tostar) bajo las condiciones del método Rancimat. Se determinó y comparó los parámetros físico-químicos de aceites de argán comestible y cosmético inmediatamente después de la preparación y después de la oxidación acelerada mediante Rancimat a temperaturas de 90 °C, 100 °C, 110 °C, 120 °C, 130 °C y 140 °C Los logaritmos naturales de la constante de velocidad cinética (valor k) variaron linealmente con respecto a la temperatura. Se pudo observar un valor creciente de la oxidación conel aumento de la temperatura. Se calculó para la estabilidad oxidativa de los aceites vegetalesy sobre la base de la ecuación de Arrhenius y la teoría del complejo activado, la frecuencia de los factores A, energías de activación Ea, los valores de Q10, lasentalpías de activación ΔH, y las entropías de activación ΔS. La oxidación acelerada y los parámetros cinéticos han demostrado que el aceite de argán comestible se puede almacenar mucho mejor que el aceite cosmético.
