Mineral content of commercial pollen.
Pollen is a natural product which is extending its marketing day by day, given that it is considered to be a dietetic product and it is consumed everyday by a broad sector of the Spanish population. In its composition it presents valuable nutrients, among which we can find minerals, which is the main object of this study. We have analysed sodium, potassium, magnesium, copper, iron, manganese and zinc in 15 pollen samples which correspond to different brands. The technique we have used is atomic absortion spectroscopy. The results show us the great potassium contribution of this natural product, with values over 400 mg/100 g, and about microelements, mainly iron and zinc, although with different results, depending on the brand which markets it, with average values of 4.01 +/- 1.00 and 3.66 +/- 1.02, respectively.
