The treatments were 70%CO2+15%N2+15%O2, 70%CO2 +30%N2, 70%CO2+ 30% O2 ,50%N2+50%O2, vacuumand clove oil at different frozen storage periods (1, 30, 60,and 90 days at -18 C). An 84 chick thigh meat pieces were utilized in this study. Polyethylene bags were used in packaging meat under vacuum, then filled with different gases. Colour parameters such as lightness (L*), redness/greenness (a*), yellowness/blueness (b*), Chroma (?C), the total colour difference (?E), and hue angle (h) were studied. The results demonstration that the modified atmosphere packaging treatments have a significant (P<0.05) effect on L*, a*, h values, but b*, ?C, and ?E parameter were not significantly affected by the treatments. Furthermore, the frozen storage periods have a significant (P<0.05) effect on L*, a*, b*, h, ?C, and ?E values. The result clarified that the effect of the interference between the modified atmosphere packaging treatments and frozen storage periods on a*, ?E, ?C, and h values was not significant, but its effect on L* and b* was significant (P<0.05). The results also showed that the highest L* value was 54.12 by using vacuumed packaging treatment on 30 days of frozen storage period. a* value was increased by using modified atmosphere packaging treatments but decreased with the increase of frozen storage period. b* value was ranged between 0.70 by control to 16.65 by using 70%CO2+15%N2+15%O2. The lowest ?E, ?C, and h values were 4.96, 2.70 and 0.53 by using70%CO2+30%N2, 70%CO2+30%N2 and clove oil on 30, 1 and 1 days of frozen storage period respectively.</p>}, number={2}, journal={Basrah Journal of Agricultural Sciences}, author={Khalaf, Jalilah H. and Al-Asadi, Majid H. and Al-Hilphy, Asaad R.}, year={2019}, month={Dec.}, pages={60–73} }
