secado por aspersión, hojas de aguacate, compuestos fenólicos, actividad antioxidante, nutracéuticosResumen
Las hojas de Persea americana Mill. son una fuente relevante de compuestos fenólicos con potencial antioxidante en salud y alimentos funcionales. Este estudio evaluó el efecto de la temperatura de secado por aspersión (160–180 °C) sobre las propiedades fisicoquímicas, tecnológicas y bioactivas de un extracto obtenido mediante disolvente eutéctico profundo y microencapsulado con maltodextrina. Se determinaron humedad residual, fluidez, rendimiento, polifenoles totales, capacidad antioxidante, cinética de liberación y actividad en carne de pollo mecánicamente deshuesada. El aumento de temperatura mejoró el rendimiento del proceso, la retención de polifenoles y la estabilidad del polvo, destacando 180 °C como condición óptima. La liberación de compuestos bioactivos se ajustó al modelo de Korsmeyer–Peppas con difusión fickiana. En la matriz cárnica, el extracto redujo la peroxidación lipídica de forma dosis-dependiente. En conjunto, el sistema microencapsulado mostró alto potencial como ingrediente antioxidante para aplicaciones alimentarias y nutracéuticas.
