title: [Silicon forms and its role in infant food].
abstract: This paper presents an attempt to assess the total content of silicon and its potentially bioavailable forms to the baby body in milk nutrient and baby foods. The measurements of the total and bioavailable silicon were conducted with the use of two analytical methods. The method of atomic absorption spectroscopy (AAS) was used for the determination of total silicon content. Bioavailable silicon was determined by means of visible light spectroscopy (VIS) with ammonium molybdate. In the group milk products the largest amount of total silicon was found in Mlekovita milk -0.54 mg/l, and Humana 2 milk formula contained the largest amount of ionised silicon-0.24 mg/l. In baby foods manufactured by Gerber the total amount of silicon was high and the average content stood at 27 mg/kg in dry matter. The largest amount of total silicon was found in Vegetables and Ham-48.19 mg/kg in dry matter, as well as bioavailable silicon--4.13 mg/kg in dry matter. Compare level of silicon in milk nutrient and baby foods to silicon content in human milk 0.05 mg/l, it was found that large excess of silicon in this foodstuffs.
