[Antiradical activity and resistance of flaxseed oil enriched with the antioxidants to oxidative changes].
Using the chemiluminescence technique, the effective concentration of antioxidants (AO) and its reactivity towards peroxyl radicals (constant k7) have been measured for the oil "Ubicato-flax" (biological active supplement) and flaxseed oil, enriched with Aronia melanocarpa extract. Ubicato-flax exhibited the highest antiradical activity but it was less resistant to oxidative changes as compared with flaxseed oil + extract. Ubicato oil produced on basis of natural AO exhibited higher antiradical activity in comparison with Ubicato oil produced on basis of the chemical synthetic AO. Aronia extract added to flaxseed oil caused marked inhibition of the increase in the peroxide value. Ubicato-flax may serve as a source of AO for not more than 6 months.
