Abstract
Se cuantificó magnesio, zinc y hierro en pulpa de café mediante espectrofotometría de absorción atómica. Se trabajaron con muestras de variedades y alturas diferentes, Catimor- Colombia y Villa Sarchi, cultivadas a 1606 y 1420 m.s.n.m. respectivamente. Se obtuvo para la muestra de las variedades Catimor-Colombia 2.71, 10.89 y 217.74 mg/100g de muestra seca de zinc, hierro y magnesio respectivamente; y para la muestra de Villa Sarchi se obtuvo 4.87, 11.55 y 158.45 mg/100g de muestra seca de zinc, hierro y magnesio respectivamente.
La muestra de las variedades Catimor-Colombia presentaron valores superiores de magnesio en comparación a la muestra de la variedad Villa Sarchi, mientras que, en esta última, se encontró mayores valores de zinc. Así mismo, las muestras trabajadas presentaron mayor contenido de magnesio, hierro y zinc en comparación a lo reportado por otros autores.
ABSTRACT Magnesium, zinc and iron were quantified in coffee pulp for atomic absorption spectrophotometry. Samples of different varieties and heights were worked, Catimor- Colombia and Villa Sarchi, grown at 1606 and 1420 m.s.n.m. respectively. It was obtained for the Catimor-Colombia 2.71, 10.89 and 217.74 mg/100g dry sample of zinc, iron and magnesium respectively; and for the Villa Sarchi sample 4.87, 11.55 and 158.45 mg/100g dried sample of zinc, iron and magnesium were obtained respectively. The Catimor- Colombia variety sample has higher magnesium values compared to the Villa Sarchi variety sample, while the latter had higher zinc values. Likewise, the samples worked had higher content of magnesium, iron and zinc compared to that is reported by other authors.
