Sledování obsahu ftalátů v obalech a jejich migrace z obalů do masných výrobků

Musilová, Eva January 2017 (has links)
This diploma thesis on the topic Monitoring of phthalates content in packaging and their migration from the packaging to the meat products deals with analysis of textile colour-printed packaging intented for packaging of meats products to find out dibutylphthalate (DBP) and di-2-ethylhexylphthalate (DEHP) content and also deals with monitoring migration of these phthalates into model meat products during storage (for twenty-eight days). The values of concentration of DBP and DEHP in packaging reached 24.0 ug.dm-2 and 103.3 ug.dm-2 of the original sample. Sample of meat product was analyzed before packaging and no phthalates were detected. After packaging and storage the highest value of DBP concentration at the end of the storage period was 11,1 mg.kg-1 and concentration of DEHP was 28,2 mg.kg-1 of the original sample. Based on the results from measurements with increasing storage time increased concentrations of these substances in meat products. In accordance with the specific migration limits (for DBP 0,3 mg.kg-1 and for DEHP 1,5 mg.kg-1) mentioned in Commission Regulation (EU) no. 10/2011 on plastic materials and articles intended to come into contact with food have been exceeded in all samples of meat products during storage.
