This study is aimed at estimating the shelf life of cooked chicken breast meat subjected to different storage temperatures. Analyses were carried out with industrialized cooked chicken breast stored at different temperatures (2, 4, 7, 10, 15 and 20°C). The shelf life was assessed through the presence of microorganisms: mesophilic, psychrotrophic, Staphylococcus, Escherichia coli and Salmonella. Analyses of color and cutting force were performed at each temperature studied. Sensory analysis was conducted under acceptability limits of 1.8. Temperature increase was found to reduce the microbiological shelf life. Industrialized cooked chicken breast had shelf life of 23, 14, 9, 6 days, 32 and 17 hours, when stored at 2, 4, 7, 10, 15 and 20°C, respectively. In the color analysis, luminosity and Chroma a* decreased while Chroma b* increased during the days of storage for all temperatures studied. Moreover, the cutting force of cooked chicken breast decreased during storage. The sensory shelf life was 11 days when stored at 2 °C and 2 days when stored at 20 °C. In conclusion can be say that the temperature changes have greater impact on microbiological growth, cutting force, color changes and sensory shelf life in industrialized cooked chicken breast meat
