| Abstract | ||
| The study was designed to examine the effects of both dietary vitamin E supplementation and pre-rigor injection with crude kiwifruit extract on some physico-chemical and sensory traits of Karadi sheep. Rams were divided equally into two treatments (T) groups. T1 group was fed a control diet and T2 group was supplemented with vitamin E. After exsanguination of rams and dressing carcasses, the three major muscles namely longissimusdorsi (LD), semimembranosus (SM) and biceps femoris (BF) were removed from both T1 and T2 carcasses, Then injected with crude kiwifruit extract at concentrations of 8 and 12% and distilled water at a rate of 10 % muscle weight. The other treatment is considered as control. The muscles samples were packed in polyethylene bags and stored at 4°C for 24hr, then kept frozen at -18°C, until the time analysis.The results showed that vitamin E alone or its combinations with injection with crude kiwifruit extracts (8 and 12%) were more effective in retarding lipid oxidation and of met-myoglobin formation with lower (p<0.05) cooking loss percentages and higher (p<0.05) moisture content and their reflection on improvement water holding capacity and sensory traits in LD, SM and BF muscles as compared with control and other treatments. LD muscle was more effective in maintenance the traits above than SM and BF muscles .It can be concluded that the presence of vitamin E in muscle together with crude Kiwifruit extract played a key role in retarding lipid oxidation and meat color, also improvement of sensory traits | ||
