Lipid Oxidation and Color Changes of Fresh Camel Meat Stored Under Different Atmosphere Packaging Systems

M Jouki and N Khazaei

Lipid oxidation, color and sensory attributes of fresh camel meat stored at 4˚C were affected by modified atmosphere packaging conditions (AP: Air packaging, VP: Vacuum packaging, MAP: 60% CO2+40% N2). The a* value were lower in samples packed under vacuum than in the other groups. Modified atmosphere packaging camel meat had no significantly (P<0.05) different TBARS value and the levels of TBARS were not positively correlated with storage time. Our study showed that even though oxidative rancidity (TBARS) increased with storage time in air-packaged samples, it did not result the deterioration of sensory quality until day 14. Sensory panel results were in general agreement with the  physicochemical changes, suggesting that the MAP had a significant impact on the quality of refrigerated camel meat. Modified atmosphere packaging of fresh camel meat accompanied by refrigeration storage enhanced product shelf life for 21 days without undesirable and detrimental effects on its sensory acceptability.
