摘要: In this work, 26 elements (Ag, Al, As, B, Ba, Ca, Cd, Co, Cr, Cs, Cu, Ga, Fe, K, Mg, Mn, Na, P, Pb, Rb, Se, Si, Sr, Ti, V, and Zn) were analyzed by inductively coupled plasma optical emission spectroscopy (ICP-OES) in seed samples: amaranth, chia, sesame, linen, quinoa. Elemental analysis showed the presence of toxic (As, Pb), as well high mineral content (Fe, Mg): The concentrations below permissible limits WHO. Chemometrics was performed cluster (CA), principal component (PCA), partial least squares discriminant (PLS-DA). all cases, a correct classification each type obtained. combination elemental (major, minor, elements) chemometrics useful to determine nutritional quality studied seeds, classify them according botanical origin. For that, method can be for raw material control food factories government labs.
