Sodium and potasium intake by dietetic produc

In view of minerals importance in human metabolism and the fact that they are needed in definite concentrations the aim of research was to evaluate some dietetic products as a source of macroelements sodium and potassium in nutrition. Sodium and potassium concentrations were determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES) method, after microwave digestion, in different kind of hard biscuits based on wheat flour or wheat flour enriched with wheat whole flour or wholemeal and soya flour. The results of analysis reveals that sodium content ranges from 0.22g to 0.77g and potassium content from 0.09g to 0.27g calculated on 100g of original matter. Depending upon their composition, 100g of investigated biscuit can cover from 5% to 20% of sodium and from 4% to 12% of potassium recommended dietary allowances, respectively.
