Abstract(s)

The mineral content and levels of trace elements in six wild underused berries (Elaeagnus umbellata, Myrica faya, Rubus grandifolius, Sambucus lanceolata, Vaccinium padifolium and Vaccinium cylindraceum) have been determined by inductively coupled plasma-mass spectrometry after microwave digestion. The inorganic content of these foodstuffs has not been previously described in scientific literature (except for E. umbellata). Hence, this information is of high interest concerning the introduction of these noncommercial berries in the mainstream market. The analytical method has been validated analyzing a certified reference material and performing recovery experiments. The results obtained have been discussed using the Recommended Daily Allowance for minerals provided by the Commission of the European Community, and a comparison between the composition of the analyzed berries and different commercialised berries has been carried out. Data obtained in this study support the consumption of these less-known berries, in particular R. grandifolius and S. lanceolata, as potential novel sources of essential minerals.
