Effects of irradiation on residues and migration levels of antioxidants and their degradation products of LDPE packaging filmThe effects of g-irradiation on residues and migration levels of antioxidants, tris(2,4-ditert-butylphenyl) phosphate (Irgafos 168), octadecylb-(2,6-di-tert-butylphenol) propionate (Irganox 1076) and their degradation products of low density polyethylene (LDPE) packaging film were investigated in the range of 0 to 200 kGy.The residues of Irgafos168 were not detected after 5 kGy and that of Irganox 1076 at 0, 5, 10, 30, 60, 100 and 200 kGy were 1126, 607, 730, 243, 126, 59 and 34 mg/kg, respective.The migration levels of antioxidants from LDPE into food stimulants, water, 4% acetic acid, 20% ethanol and olive oil were decreased with increasing g-irradiation.The decomposition products, 1,3-di-tert-butybenzene and 2,4-di-tert-butylphenol, of Irgafos 168 were identified with GX/MSD and the residues were increased with increasing g-irradiation in LDPE.However, the decomposition products of Irganox 1076 could not be identified by same method.
