    Effect of high-oxygen MAP on the pH value and ammonia content in organic chicken meat

  • Original language description

    The aim of this study is evaluation the effect of high-oxygen MAP obverse air atmosphere packaging on pH and ammonia content in breast and thigh (muscle without skin) of chicken from organic production system. In the total 48 samples (halfcarcasses of fresh chicken) has been obtained from organic production farm of broilers and storage at 2 +- 2oC. Half of samples (24) was been packaged with MAP (80% O2/20% CO2) and 24 samples with air atmosphere. Measurement of gases mixture in MAP as well as pH value and ammonia content in the breast and thigh of organic chicken has been conducted at 2, 7, 10 and 14 day of storage. The percentage of O2 in MAP decreased significantly (P < 0.05) at 7 day to the end period of storage, whereas the amount of CO2 increased significantly (P < 0.05) from 2 day (16.43%) to 14 day (21.59%) ofstorage. The pH values of breast and thigh in MAP remained without any significant differences (P > 0.05) during storage period. The amount of ammonia in the breast and thigh of organic chicken which aerobically packaged was significantly higher than MAP at 10 day and 14 day of storage. According to the result of present study the MAP had positive effect on the production of ammonia in organic chicken meat during storage in compared with aerobically packaged.
