Cuantificación de cadmio en muestras de almendras Theobroma cacao venezolano

Abstract

Desde la entrada en vigencia de la normativa de la Unión Europea en 2019 sobre los límites máximos permitidos de metales pesados, ha aumentado el interés por la cuantificación de estos elementos en el cacao venezolano. En este estudio, se determinó la concentración de cadmio (Cd) en nueve muestras de granos de cacao provenientes de distintas regiones del país, analizando por separado la cáscara y el nib. Se optimizó un proceso de digestión de muestras mediante un diseño factorial y se empleó para la cuantificación espectroscopia de absorción atómica con atomización por llama, utilizando un espectrofotómetro de fuente continua en modo secuencial rápido. La precisión del método se evaluó a través del cálculo del porcentaje de recuperación en determinaciones inter-diarias e intra-diarias. Los resultados arrojaron concentraciones de cadmio en un rango de 1,4 a 7,2 mg kg⁻¹, superando el límite establecido por la normativa europea de 0,6 mg kg⁻¹.
