Abstract: | Three sour cherry and three table grape cultivars were analyzed using inductively coupled plasma optical emission spectrometry.
The elements: Na, K, Ca, Mg, Fe, Cu, Zn, Mn, Cr, Cd, Co, Pb, and Ni were detected in all samples; four elements are very abundant
(K, Na, Ca, and Mg), and four are not abundant (Cu, Fe, Mn, and Zn). Five of them are trace elements (Cr, Cd, Co, Pb, and
Ni) at <0.1 mg/kg. Among the 13 elements analyzed, potassium was the most abundant element distributed throughout all categories
of fruits. Iron was the predominant minor element constituents. Manganese concentration was the highest in table grape cultivars.
The accuracy of the results was evaluated by spike recovery tests. Analysis of variance was used to establish the metals with
significant difference in mean content between the cultivars from sour cherries and between table grapes. Principal component
analysis was used to evaluate the distribution of metals. |
