Abstract

CABALLERO, J.M. et al. Mineral composition of different types of Canarian gofio: factors affecting the presence of Na, K, Mg, Ca, Mn, Fe, Cn and Zn. Nutr. Hosp. [online]. 2014, vol.29, n.3, pp.687-694. ISSN 1699-5198.  https://dx.doi.org/10.3305/NH.2014.29.3.7099.

The contents of Na, K, Mg, Ca, Mn, Fe, Cu and Zn were analyzed and evaluated in 181 samples of various types of gofio produced from different roasted cereal grains. Samples were analyzed by ICP-OES. Based on a daily gofio intake of 30 g/day for adults and 15 g/day for children, the daily intake of each metal, and its percentage contribution to the RDAs established for the Spanish population, were estimated. The metal with the highest concentration was K (2189 ± 766 mg/kg). The lowest concentration was observed for Cu in corn gofio samples (2.05 ± 0.36 mg/kg). With respect to daily intake, it is noteworthy that gofio contributes significantly to the recommended allowance of copper (53.77%-71.45% of the RDI), depending on the population group considered and on the type of gofio.
