In control and all of the treatments an increasing trend in TBARS values was observed until day 5 and 15, respectively that followed by a decrease until day 20 of storage. This pattern was similar to that reported in chicken breast meat which might be attributed to initial formation of MDA and its possible decomposition during the later stages of storage. However, PJ in all of treatments decreased lipidoxidation significantly (P b 0.05) as compared to the control. The large amount of phenolics contained in PJ may cause its strong antioxidant ability. Our results were in agreement with previous studies . Chitosan enriched with ZEO (1 and 2%) significantly (P b 0.05) increased antioxidant activity of PJ against lipid oxidation. This increase was probably due to protecting effect of chitosan on numerous degradative reactions of total phenolic content of PJ during storage
