Influence of ascorbic acid on antioxidant properties of albumin preparations against linoleic acid solutions and emulsions, as well as DPPH^• stable radical scavenging ability were evaluated. In most model systems high activity of albumins was proved. Ascorbic acid addition had the best antioxidant effect in emulsions and resulted in decrease of peroxides in linoleic acid solutions. The biggest changes of antiradical activity after ascorbic acid addition were observed for proteins exhibiting lower scavenging ability.
