| heal.abstract | Whilst considerable research has been conducted on the stability of plastics additives during processing, there is, on the other hand, a lack of studies on the stability of the same additives in food simulants in the published literature. lit the work presented a systematic study has been undertaken on the stability of five selected commercial plastics additives (Irganox 3114, Irganox 1035, Irganox 245, Irganox 1098 and Irgafos P-EPQ) in the three EU-official aqueous food simulants (distilled water, 3% aq. acetic acid and 15% aq. ethanol) and in an alternative fat simulant (95% aq. ethanol) tinder two different time/temperature exposure conditions (10 days at 40 degrees C and I h at 100 degrees C). To enable quantitative analysis of the additives for this investigation, a simple and rapid HPLC method with UV detection was developed. The results obtained showed that the four Irganox-type additives under investigation were practically stable under the applied exposure conditions in all of the employed food simulants. Only Irganox 3114 exhibited a relatively low degree of instability in the ethanolic food simulants. Concerning Irgafos P-EPQ, a mixture of at least seven constituents, a remarkable degradation in ethanol and acetic acid solutions was observed. The developed HPLC method is also considered to be applicable for stability testing of other Irganox-type additives both in aqueous and fatty food simulants. | en |
