Detection of 20 Phthalate Esters in Different Kinds of Food Packaging Materials by GC-MS/MS with Five Internal Standards

Abstract Background: Phthalate esters (PAEs) are a group of chemical compounds widely used as plasticizers to increase the flexibility of plastics that are used in the manufacturing of kitchen utensils and food containers. Objective: In this study, a simple, rapid, and sensitive method for the determination of 20 PAEs in different kinds of food packaging materials has been developed. Methods: Samples injected with five internal standards were extracted with acetonitrile saturated with n-hexane and then detected by GC-MS/MS without a purification step. Results: The standard calibration curves were linear for all analytes over the concentration range of 5–500 μg/L, and the correlation coefficients ranged from 0.9913 to 0.9999. The LODs and LOQs were in the ranges of 1.7–62.5 and 5.5–208.3 μg/kg, respectively. The accuracy of this method was evaluated by measuring the recovery from spiked samples. The recoveries of all 20 phthalates from samples spiked at three different concentrations were measured, and the recovery was in the range of 82.1–110.8% and the relative standard deviation range of recovery result (n = 6) was 0.3–9.7%. Conclusions: The method presented here is simple, rapid, and sensitive and can be applied to large-scale detection of PAEs in plastic materials. Highlights: Instead of only one solvent, acetonitrile saturated with n-hexane was used as the extraction solvent. Samples were pretreated without a purification step. Five internal standards were used for quantitative determination.

A new method was established for detecting a series of photoinitiators (PIs) in printed cartonboard food-packaging materials, which were benzophenone (BP), 4-methylbenzophenone (MBP), 1-hydroxycyclohexyl phenyl ketone (Irgacure184), ethyl-4-dimethylaminobenzoate (EDAB), 2-ethylhexyl-4-dimethylaminobenzoate (EHDAB) and 2-isopropylthioxanthone (ITX) by gas chromatography–mass spectrometry (GC/MS). Extraction was carried out with ethyl acetate by ultrasonic solvent extraction. Samples were analyzed by GC/MS in selected ion monitoring (SIM) mode. The results indicated that six kinds of PIs had good linear relations (R2>0.9989) in the range of 10~200 μg/L. Limit of Detections (LODs) and Limit of Quantifications ( LOQs ) of all kinds of PIs were 0.3~2.6 μg /kg and 1~8 μg/kg, respectively. The recoveries of six kinds of PIs at three kinds of concentrations researched (0.30 μg/kg, 0.60 μg/ kg, 1.0 μg/kg) were ranging from 66.7%~89.4%, with the Relative Standard Deviation (RSD) of 4.2%~10.6% (n=6). The results also suggested that PIs were detected in food packaging materials.

A rapid method based on high performance liquid chromatography-tandem mass spectrometry (HPLC/MS/MS) with accelerated solvent extraction (ASE) or solid phase extraction (SPE) was developed for quantitative determination of perfluorooctane sulfonate (PFOS) in the coatings of nonstick pot, food packaging materials, waterborne coatings containing fluoride and fire-fighting foams. The linear calibration curve was obtained in the range of 0.002 - 0.1 μg/mL with a linear correlation coefficient (R2) of 0.998 or 0.999. The recovery for PFOS was in the range of 93.4 - 103% with relative standard deviation of 0.48 - 3.59%. The detection limit for PFOS was 0.4 μg/m2 with a signal-to-noise ratio of 10 for the coatings of nonstick pot and the food packaging materials, and 0.0002% for waterborne coatings containing fluoride and fire-fighting foams, both of which meet the restriction requirement for PFOS content in these chemical materials and consumer products in the EU directives.

Overconsumption of plastic goods and improper handling of petroleum-derived plastic waste have brought a plethora of negative impacts to the environment, ecosystem and human health due to its recalcitrance to degradation. These drawbacks become the main driving force behind finding biopolymers with the degradable properties. With the advancement in biopolymer research, polyhydroxyalkanoate (PHA) and poly(lacyic acid) (PLA) and its composites have been alluded to as a potential alternative to replace the petrochemical counterpart. This review highlights the current synthesis process and application of PHAs and PLA and its composites for food packaging materials and coatings. These biopolymers can be further ameliorated to enhance their applicability and are discussed by including the current commercially available packaging products. Factors influencing biodegradation are outlined in the latter part of this review. The main aim of this review article is to organize the scattered available information on various aspects of PHAs and PLA, and its composites for packaging application purposes. It is evident from a literature survey of about 140 recently published papers from the past 15 years that PLA and PHA show excellent physical properties as potential food packaging materials.
