Abstract
The effect of ionizing radiation in raw, vacuum and modified atmosphere packed chicken legs and storage at 4±1oC was evaluated on the basis of thiobarbituric acid reactive substances (TBARS) The vacuum-packed samples exhibited a gradual increase in TBARS values proportional to the radiation dose in the course of the storage period, but the differences were not statistically significant (p>0.05) up to the fourteenth day when the samples exposed to the different radiation doses applied were compared. Samples irradiated with 1.5 kGy and 3.0 kGy and packaged under modified atmosphere showed significantly lower TBARS values as compared to the vacuum-packaged samples, except after 20 and 26 days storage. The maximum TBARS values were obtained from samples irradiated with 7.0 kGy, with mean values of 2.13 and 1.52 mg.kg-1 of malonaldehyde, for the vacuum and modified atmosphere packages respectively.References
