摘要:Phthalates are compounds found in additives that frequently added into recycled paper-based packaging material.Potentially harmful substances present in the recycled paper comprise the residues of printing inks,varnishes,adhesives and other substances.Foods that are in direct contact with recycled paper packaging containing diisopropyl-naptalene,benzophenone,terphenyl hydrogenated,primary aromatic amine,polyaromatichydrocarbon (PAH) and phthalates.Trace amounts of phthalates can leach out of food packaging and get into the food,especially for fat rich-food products.One of phthalates,di-n-butyl phthalate (DBP) was reported as endocrine disrupter.In high doses,DBP has been shown to harm the reproductive system of rodents.This research aimed to identify and quantify DBP from recycled paper-based food packaging and its migration into food simulant.The method based on ultrasound-assisted solvent extraction (USE) followed by gas chromatography-mass spectrometry (GC-MS) analysis.The developed method was validated.It had linearity value (R2 ) of 0.999,recovery percentage of 91.4% - 103.6%,limit of detection (LOD) and limit of quantification (LOQ) at 0.04 mg/L and 0.06 mg/L,respectively.Analyses of DBP from five commercial duplex papers were found to vary from the range of 1.7 to 5.8 mg/kg.Migration rate,which was measured from direct contact between the papers and ethanol 95% as food simulant for 2 hours at 40°C was 4.7 mg/dm2.The DBP migration exceeded Commission Regulation (EU) No.10/2011 (0.3 mg/kg or 0.05 mg/dm2 ).These results indicate that the use of recycled paper as the primary food packaging is not recommended,especially for fatty food.
