ABSTRACT. Wide spectrum of garlic biological activity is connected with antioxidant properties and peculiar sulfur and selenium derivatives. Significant anti-carcinogenic effect of these compounds and especially methylated forms of selenium containing aminoacids and peptides became the basis for technology development of selenium enriched garlic production in hydroponic conditions. The aim of the present study was evaluation of biochemical characteristics and element composition of selenium enriched garlic using ground application of sodium selenate The total dose of sodium selenate 75 mg per m2 resulted in 16.7 biofortification level, 20% increase o antioxidant activity and 40% increase of polyphenol content. Biofortification with selenium did not affect the content of macro elements but significantly decreased accumulation of heavy metals (Ni, Al, Cd, Cu, Pb), and also I and Mo. Additional incorporation of selenium into garlic bulbs elevated the levels of trace elements possessing antioxidant properties: Si, Mn, Zn. The results of the investigation became the basis for the development of regional standard on production of functional food species – powder of garlic fortified with selenium.
