| Abstract (English): |
The objective of this study was to determine the proximal composition, the fatty acid profile, the content of minerals, tannins, polyphenols, anthocyanins, the antioxidant capacity and the color of the acai pulp (Euterpe oleracea Mart) collected in the Venezuelan Amazon from 2 harvests of the year 2005. For the proximal analysis, the official methods were used and the minerals were analyzed by the induced plasma technique. Polyphenols, tannins and anthocyanins were determined by spectrophotometric methods and the antioxidant capacity was analyzed by DPPH method. Results in dry basis indicated that acai has a high lipids content (49.4% and 33.1%), proteins (13.8% and 9.3%), ash (5.2% and 2.2%) and total dietary fiber (27.3% and 18.0%). It stands out that 71% of the acai fat is oleic acid and that the Fe content of the first and second harvest was 0.023 and 0.015 mg/100g, respectively; polyphenols 5.02 and 2.20 g/100 g; tannins 0.70 and 1.37 g/100g; anthocyanins 0.73 and 1.60 g/100g and the antioxidant capacity 88.03 and 87.87%, respectively. It is concluded that the acai or manaca collected in the Venezuelan Amazon has a high nutritional value and contains antioxidant compounds which suggests the need to industrialize it to take advantage to the maximum of its properties.

El objetivo de este estudio fue determinar la composición proximal, el perfil de ácidos grasos, el contenido de minerales, taninos, polifenoles, antocianinas, la capacidad antioxidante y el color de la pulpa del acai (Euterpe oleracea Mart), recolectada en el Amazonas venezolano, provenientes de 2 cosechas del año 2005. Para el análisis proximal se utilizaron métodos oficiales y los minerales se analizaron mediante la técnica de plasma inducido. Los polifenoles, taninos y antocianinas se determinaron por métodos espectrofotometricos y para la capacidad antioxidante se siguió el método del DPPH. Los resultados expresados en base seca indicaron que el acai de las 2 cosechas tiene un alto contenido de lípidos (49,4% y 33,1%,), proteínas (13,8% y 9,3%), cenizas (5,2% y 2,2%,) y fibra dietética total (30,9% y 20,0%,). Destaca que el 71% de la grasa es ácido oleico y que el contenido de Fe de la primera y segunda cosecha fue 0,023 y 0,015 g/100g, respectivamente; polifenoles 5,02 y 2,20 g/100 g; taninos 0,70 y 1,37 g/100g; antocianinas 0,73 y 1,60 g/100g y la capacidad antioxidante fue 88,03 y 87,87%, respectivamente. Se concluye que el acai o manaca recolectada en el Amazonas venezolano tiene un alto valor nutricional y contiene compuestos antioxidantes que sugieren la necesidad de industrializarlo para aprovechar al máximo sus propiedades.
