A systematic study on the stability of selected polymer antioxidants in EU official aqueous and alternative food simulants using HPLC

摘要

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. In the work presented a systematic study has been undertaken on the stability of five selected com- mercial plastics additives (Irganox 3114, Irganox 1035, Irganox 245, Irganox 1098 and Irgafos P-EPQ) in the Three EU-official aqueous food simulants (distilled water, 3/100 aq. acetic acid and 15/100 aq. ethanol) and in an alternative fat simulant (95/100 aq. ethanol) under two different time|temperature exposure conditions (10 days at 40 deg. C and 1 h at 100 deg. C).
