    Fresh chicken legs were packaged in a modified atmosphere (MA) or in air and stored at 6-degrees-C. The changes in gas composition, microbiological counts, pH of the skin and sensory quality were monitored after 0, 3, 6, 8, 10, 12 and 13 days of storage at 6-degrees-C. The CO2 concentration of all samples packed in MA decreased during the first 3 days of storage, followed by a gradual increase after the third day, while O2 and N2 showed a corresponding decrease. The pH of the skin stored in air increased rapidly during 6 days of storage while a decrease in pH occurred in all the samples stored in MAP. The best gas mixture for extending shelf life and sensory acceptability was 90% CO2/10% O2
