Study of mineral profile of Montilla-Moriles “fino” wines using inductively coupled plasma atomic emission spectrometry methods

Abstract The characterization of “fino” wines from the Montilla-Moriles denomination of origin (DO) according to their mineral content was carried out by measuring twelve elements (Zn, P, Mn, Fe, Mg, Cu, Ca, Al, Sr, Ba, Na, K) using Inductively coupled plasma atomic emission spectrometry (ICP-AES) in fifty samples. The results obtained showed that mineral data sets were non-normally distributed and accordingly, non-parametric statistics (median, interquartile range) were applied. The interrelation of element couples was studied through the Spearman non-parametric sample correlation.
