Taurine and ascorbic acid, either alone or in combination, showed no differences (P>0.05) to the control samples..
As stated above, rosemary and rosemary+ascorbic acid had a pronounced antioxidant effect at all storage times.
The antioxidant properties of rosemary have been attributed to a variety of isoprenoid quinones, capable of terminating free radical reactions and quenching reactive oxygen species.
Our results were comparable to those of Yildiz-Turp and Serdaroglu (1998).
They also confirmed those reported by McCarthy, Kerry, Higgins, Buckley, Lynch, and Morrissey (1998), according to which rosemary was a strong and efficient antioxidant, and even more so in the presence of ascorbic acid.
The addition of ascorbic acid was completely ineffective in preventing lipid oxidation.
Nevertheless, the antioxidant activity of ascorbic acid may depend on its concentration.
According to our results, ascorbic acid showed a synergistic antioxidant effect when used in combination with carnosine.
