Abstract: En los procesos fisiológicos desarrollados en la alimentación, se pueden encontrar antinutrientes que podrían influenciar en el organismo como estimulantes o depresores de algunas funciones, dentro de estos la cafeína, por lo que es necesario, conocer sus concentraciones por métodos confiables que garanticen la inocuidad alimentaria. Se cuantificó cafeina en pulpa de café mediante UPCL (Cromatógrafo Líquido de Ultraperformance). En 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 452.3 mg/100g de muestra seca y para la muestra de Villa Sarchi se obtuvo 340.9 mg/100g de muestra seca. Se determinó que la muestra de las variedades Catimor-Colombia presentó mayor cantidad de este metabolito en comparación con la muestra de Villa Sarchi. Los resultados presentaron menor contenido de cafeína en comparación a otros autores. Se propone este método que permitiría disminuir el tiempo y el costo de los reactivos utilizados.
ABSTRACT In the physiological processes developed in the diet, antinutrients can be found that could influence the body as stimulants or depressants of some functions, within these caffeine, so it is necessary to know their concentrations by reliable methods that guarantee food safety. Caffeine was quantified in coffee pulp using UPCL (Ultraperformance Liquid Chromatograph). In samples of different varieties and heights, Catimor- Colombia and Villa Sarchi, cultivated at 1606 and 1420 m.a.s.l.m. respectively. It was obtained for the sample of the varieties Catimor-Colombia 452.3 mg / 100g of dry sample and for the sample of Villa Sarchi was obtained 340.9 mg / 100g of dry sample. It was determined that the sample of the Catimor-Colombia varieties presented a greater amount of this metabolite compared to the sample of Villa Sarchi. The results were lower in caffeine compared to other authors. This method is proposed to reduce the time and cost of the reagents used.
