GONZALEZ, Anara; RONDON, Carlos  y  PINO, Karina. Macrominerals content in coroba palm (attalea macrolepis) fruit flour in five zones of Cedeño Municipality, Bolivar State, Venezuela: Contribution to daily dietary intake. Saber [online]. 2013, vol.25, n.4, pp.423-430. ISSN 1315-0162.

The coroba is a native palm from Bolivar State, Venezuela, and its fruit is used by residents of the area to prepare a variety of foods. The aim of this study was to determine the calcium (Ca), magnesium (Mg), potassium (K), and sodium (Na) content in flour obtained from the mesocarp of coroba fruit (Attalea macrolepis), in order to provide information on their nutritional composition for human consumption. For this purpose, mature fruits were randomly taken from wild palms located in five areas of Cedeño municipality. Macroelements were analyzed by atomic absorption spectroscopy flame, after acid digestion of the sample. The average Ca, Mg, K and Na content were in the range of 7.2 to 26.5 mg/100 g, 58 to 196 mg/100 g, 200-737 mg/100 g and 5.8 to 7.8 mg/100 g, respectively. Macroelements concentrations showed significant variations (ANOVA, p < 0.05) that are associated with the harvesting area of the fruits and maturity. According to the dietary reference intake values (DRI), the consumption of 100 g of flour would provide about 1.5% of Ca, 42% Mg, 10% K and 0.4% Na. These results suggest that this flour can be considered as an important source of essential nutrients that could be an alternative to complement commercial flours used by the Venezuelan population if additional studies confirm its nutritional importance.
