Vitamina C y color superficial en tomate y pimentón verde: efecto de los tratamientos térmicos
Resumen
El objetivo de esta investigación fue determinar el efecto de los tratamientos térmicos en la concentración de ácido ascórbico y color superficial en frutos de tomate y pimentón. Muestras de 100 g se sometieron a la cocción con microondas (800 w durante 2 minutos), horno (200°C) vapor (97 °C) y agua (98 °C) durante 10 minutos, se enfriaron rápidamente a 5 °C y se procedió a determinar la concentración de ácido ascórbico, y las coordenadas colorimétricas CIEL*a*b*. El tratamiento con horno presentó estadísticamente la mayor reducción de ácido ascórbico al registrar pérdidas del 80% de este antioxidante, y en pimentón verde, el tratamiento de cocción con agua redujo en un 51,73% la concentración de este micronutriente. Por otra parte, los tratamientos térmicos no afectaron el color superficial de los frutos de tomate y pimentón.
