Determinación del contenido de zinc en arroz y otros agroproductos por fluorescencia de rayos X

Otoniel Denis Alpízar, Oscar Díaz Rizo

Resumen

Se reporta el contenido de zinc en alimentos de consumo regular en Cuba (arroz, algunos vegetales y raíces comestibles). Las concentraciones se determinan por fluorescencia de rayos X empleando un juego de patrones de matriz orgánica dopados con zinc. La validación de la metodología analítica se realiza con los materiales de referencia certificados AIEA 393 y MAB3/ TM. Los resultados muestran al arroz como el producto agrícola de mayor bioacumulación de zinc, siendo la principal fuente de Zn en la dieta de la población cubana.
