RAMOS, Maria Isabel Lima et al. Nutritional quality of the pulp of bocaiuva Acrocomia aculeata (Jacq.) Lodd.. Ciênc. Tecnol. Aliment. [online]. 2008, vol.28, suppl., pp. 90-94. ISSN 1678-457X. http://dx.doi.org/10.1590/S0101-20612008000500015.
With the aim at stimulating the consumption of natural food from the Brazilian Cerrado (vast tropical savanna ecoregion of Brazil), the contens of moisture, lipid, protein, carbohydrate, ash, fiber, minerals, and main carotenoids were determinated in the bocaiuva Acrocomia aculeata (Jacq.) Lodd. pulp. The edible portion of the fruit (pulp and kernel) corresponded to 50% of the whole fruit. The pulp presented 52.99% of moisture, 8.14% of total lipids, 1.5% of protein, 22.08% of carbohydrates, 1.51% of ash, and 13.76% of fiber. The energetic value was estimated to be 167.67 kcal.100 g-1 of wet pulp, which is higher than the other fruits from this region. Among the minerals examined, potassium was the element in higher concentrations (766.37 ± 18.36 mg.100 g-1) followed by calcium (61.96 ± 2.30 mg.100 g-1) and copper (36.70 ± 0.0 mg.100 g-1). The bocaiuva pulp may be classified as a rich source of copper for children, as a source of zinc and potassium for children, and as a source of copper and potassium for adults according to the dietary recommendation intake of those minerals. The bocaiuva pulp can be considered as rich in β-carotene (49.0 ± 2.0 µg.g-1 of integral pulp), the predominant carotenoid identified in the pulp, which can contribute to the enrichment of the regional diet, in supplementary diet programs, as a natural source of that nutrient as well as of vitamin A, copper, potassium and zinc minerals.
