Abstract

The objective of this research was to evaluate the effect of packaging in 100% air and vacuum, combined with radiation (2 kGy and 3 kGy), on chicken breast fillet shelf-life by evaluation of bacterial deteriorants growth and pH variation parameters. The vacuum packaging increased shelf-life, when compared to commercial packaging in 100% air, both in non-irradiated and irradiated to 3 kGy fillets. The irradiation increased the shelf-life of fillet samples at both doses. The lactic acid bacteria were the organisms that most developed in irradiated samples, showing greater radioresistance, as compared to other microorganisms studied, while the enterobacteria showed greater sensitivity to treatment with ionizing radiation. The vacuum packaging, combined with irradiation, can be used to improve the safety of chicken breast fillets and to extend its shelf-life.

KEY-WORDS: Deterioration; chicken meat; vacuum packaging; meat radiation.
