Linear and cyclic oligomers are unavoidable non-intentionally added substances (NIAS) present in food contact materials made from common polyesters such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT) and polyester coatings. Although polyester oligomers can migrate into fats in significant amounts in high-temperature processes...

Bei der Nutzung von z.B. Polyethylenterephthalat (PET) für Getränkeflaschen und Trays oder Polybutylenterephthalat (PBT) für Küchenartikel können Oligomere in Lebensmittel migrieren. Die Monomere dieser Polykondensationskunststoffe sind mit Migrationsgrenzwerten in der Kunststoff VO 10/2011 gelistet (TPA: 7,5 EG: 30 BD : 5 mg/kg Lebensmittel). Bish...

... Two terephthalates were included in the study; the PET oligomer bis(2-hydroxylethyl) terephthalate (BHET) was shown to degrade by 69.9% after a 4 h incubation in an intestinal-fluid simulant while the plasticizer di(ethylhexyl) terephthalate degraded by 35.1% after the simulation with both the gastric juice and intestinalfluid simulant. Eckardt et al. (2019) investigated the hydrolyzability of cyclic PBT oligomers; a cleavage of approximately 99% (cyclic dimer, CT 2 B 2 ) and 96% (cyclic trimer, CT 3 B 3 ) was observed after a 4 h incubation in the intestinalfluid simulant with an addition of 1-2% organic solvent to improve the solubility. A lower degradation rate of approximately 74% (CT 2 B 2 ) was observed without a solvent addition, proving that the solubility of the oligomer is a significant factor for the hydrolysis rate (as proposed by Ulrich et al. [2018]). ...
