[Detection of treatment of chicken breast with ionized rays and gradation of radiation dosage with the help of headspace gas chromatography and discriminant analysis evaluation].
Chicken breast was irradiated with doses of 3, 5, and 7 kGy. Headspace gas chromatographical analysis demonstrated the tendency that the amounts of volatile compounds (mainly pentanal, hexanal and heptanal) are higher in irradiated samples in comparison with non irradiated. Statistical evaluation of the gas chromatograms by discriminant analysis enabled the detection of irradiation. Unknown samples could be classified in the groups "un-irradiated" or "irradiated" in most cases.
