The aim of this paper is the determination of the specific migration of an plasticizer and an organotin heat stabilizer (IRGASTAB 17 MOK) from plasticized and rigid (PVC) into organic liquids hexane and ethanol simulating fatty food. The migration test conditions were 10 days at 40°C and 2 hours at 70°C. FTIR and UV-Visible at 490 nm spectroscopy and gas chromatography were used to investigate the migration phenomena. The influence of various parameters such as temperature, time of contact and the nature of food simulant were considered. The results show that plasticizer accelerates the heat stabilizer migration. On the other hand that gas chromatography could be substituted by FTIR spectroscopy to investigate the DBP migration phenomena. It is a simple, low cost and rapid method which can be used.
