Summary:
Plastic is widely used as packaging material, because it has a lot of advantages. Polyethylene teraphthalate (PET) is a polymer that belongs to the family of polyesters. PET is one of the best types of raw material for packaging manufacture. So, the existence of a method that reliably detects the presence of its monomers at food, is presumed to be necessary.
Food-package interactions include, amongst other, transfer of gases, vapor, water or other compounds of low molecular weight. The determination of total and specific migration is a complex procedure, as, at the same time, mass transfer from and towards the container, may occur.
At this study, a method is developed and validated by using a high performance liquid chromatographic system. All studies were performed with the HPLC system of Agilent company, 1100 series model.
The method which is developed and validated, is referred to detection and quantitative determination of a migrating compound at foodstuff. The samples examined are plastic bottles, with a capacity of 330 mL, which are used for bottling drinking water and refreshments. The last two are simulated by distilled water and aqueous solution of 3% w/v acetic acid, respectively. So, all the working solutions and the experimental study in general, have been performed twice, the first time with distilled water as a solvent and secondly using the aqueous solution of 3 % w/v acetic acid as one.
