Abstract
Slices of chicken breast were subjected to microwave heating 750 W 3 min and further storage in different conditions refrigeration at 4 °C and freezing at −18 °C combined with aerobic vacuum and modified atmosphere packaging Evaluation of the intensity of the oxidation process was carried out A 16fold increment in the amount of cholesterol oxidation products COP was found as a consequence of microwave cooking 4586 μg/g lipid after microwave and 288 μg/g lipid in raw samples 7ketocholesterol was the most affected COP by microwave accounting for a 25 of the total COP Storage of microwaved samples under aerobic refrigeration led to the highest oxidation status with the following values peroxide 1941 meqO2/kg lipid TBA 032 ppm and COP 12350 μg/g lipid MAP refrigerated samples showed 5094 μg/g lipid of total COP an amount slightly higher than in vacuum conditions 4681 μg/g lipid Under frozen storage MAP and vacuum samples showed the lowest amounts of total COP 2976 and 3928 μg/g lipid respectively
