[Study of mineral content of natural or fruits yogurts commercialized in São Paulo, Brazil].
The contents of the macrominerals Na, K, Ca, Mg, and P and the microminerals Fe, Zn, Cu, Mn, Sn and Ni, present in 44 samples of natural or fruits yogurts, of 9 different brands, available in the commerce of São Paulo State, Brazil, were evaluated. Acid digestion assisted by microwave and the determination of the elements by inductively coupled argon plasma atomic emission spectrometry (ICP-OES) were employed. The results showed that the yogurts are good sources of Ca, P and K, reasonable sources of Na, Mg and Fe, and poor sources of Zn and Cu. The multivariate analysis showed non-significant differences among the brands and the flavors studied.
