Comparison of Mineral- and Protein Content between Conventional, Organic and Biodynamic Swedish Winter Wheat with Atomic Absorption Spectrophotometry and Elemental Combustion Analysis.

<p> </p><p>Correlation between production method and mineral-, cadmium- and protein content were sought for Swedish winter wheat. The wheat was grown according to conventional, organic or biodynamic principles. The minerals; iron, zinc, magnesium, copper and the heavy metal cadmium were analyzed with atomic absorption spectroscopy. Protein was analyzed with elemental combustion analysis. All together, 17 samples were analyzed; nine from the still ongoing Bollerup field trial in Skåne and eight from four different farm pairs in the midst of Sweden.</p><p>The Bollerup field trials showed that organic wheat had a higher concentration of iron than conventional. Both organic and biodynamic wheat had a higher concentration of zinc than conventional. Magnesium concentration was higher in biodynamic wheat than in conventional grown wheat. Differences between production methods were in the range of 7.5 and 17%.</p><p>No unmistakable connections were found between any of the parameters and production method for the farm pairs. However, a tendency for more minerals in organic/biodynamic wheat was seen for all minerals but iron.</p><p>Due to unclean equipment, analyzing of cadmium contents could not be completed.</p>
