Plasticisers in poly(vinyl chloride) gasket seals and in food matrixes: food safety implications and analytical solutions by mass spectrometry

Lids seal against the glass rim with gaskets consisting of plasticized PVC and represent an issue as migration of plasticizers from these gaskets into foods. The plastisols used typically contain 25¿45% plasticizer, frequently epoxidized soy bean oil and sometimes phthalates, sebacates, citrates, acetylated mono/diglycerides and very recently with the promising alternative of polyadipates. Migration into the food can occcur both during sterilisation and storage; furthermore PVC degradation could induce the elimination of HCl and the correspondent potential formation of other derivatives. Toxicological data and legislative restrictions are not available for all the plasticizers and derivatives involved in this contest; there is also a lack for adequate analytical strategies for some of them. Mass Spectrometry combined with Gas Chromatography and\or Liquid Chromatography demonstrates to be the correct solutions either for single-target or multiresidual analysis of plasticisers and additives in PVC gaskets and also in the correspondent foodstuffs. In particular, a challenge task is reserved to the elucidation of the composition and quantification of the migrated material < 1000 Da derived by different polyadipates available on the market. Finally, high resolution MS instruments, possibly coupled to Ultra High Performance Liquid Chromatography can be further helpful for characterizing traces related to plasticizer derivatives.
