Microbiology of cooled chicken portions stored in the controlled atmosphere and in the air.

Author(s) : KUSEWICZ D., PIATKIEWICZ A., KRALA L., MICHALOWSKI S.

Summary

Comparative investigation of the effect of controlled atmosphere (75% CO2, 20% N2, 5% O2) and air on microbiological changes in breasts and thighs of chicken cooled by the air-water method and stored at temperature 1-3 deg C was carried out. It was found that in breast muscles the level of mesophilic organisms was 10 times lower and the total count of psychrotrophic organisms was 100 times smaller than in thigh muscles. During a two-week chilled storage of both types of samples the above mentioned differences in the level of meat contamination were preserved. Results of comparison of controlled atmosphere samples and air samples are given (Pseudomonas, Lactobacillus). The air samples deteriorated earlier due to the activity of bacterial microflora of proteolytic abilities. Thighs deteriorated faster than breasts.
