“…Chromatographic techniques including high-performance liquid chromatography (HPLC) [6][7][8], gas chromatography (GC) [9,10], liquid chromatography-mass spectrometry (LC-MS) [11,12], and gas chromatography-mass spectrometry (GC-MS) [13,14] were used as analytical methods. Meanwhile, different experimental conditions and procedures have also been employed to study specific migration levels of additives into food simulants [15][16][17][18][19].…”

Summary. The use of polypropylene materials in industry for food packaging is increasing. The presence of additives in the polymer matrix enables the modification or improvement of the properties and performance of the polymer, but these additives are potential risk for human health. In this context, an efficient analytical method for the quantitative determination of three antioxidants (2,6-di-tert-butyl-4-methylphenol (BHT), dibutylhydroxyphenylpropionic acid stearyl ester (Irganox 1076), and tns-(2.4-ditert-butyl)-phosphite (Irgafos 168)) and five ultraviolet stabilizers (2-(2′-hydroxy-5′-methylphenyl) (UV-P), (2′-hydroxy-3′-tert-5′-methylphenyl)-5-chloroben zotriazole (UV-326), 2-(2′-hydroxy-3′,5′-di-tert-butylphenyl)-5-chlorobenzotriazole (UV-327), 2-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol(UV-329), and 2-hydroxy-4(octyloxy) benzophenone (UV-531)) in polypropylene food packaging and food simulants by high-performance liquid chromatography (HPLC) has been developed. Parameters affecting the efficiency in the process such as extraction and chromatographic condition were studied in order to determine operating conditions. The analytical method showed good linearity, presenting correlation coefficients (R ≥ 0.9977) for all additives. The limits of detection and quantification were between 0.03 and 0.30 μg mL −1 and between 0.10 and 1.00 μg mL −1 for eight analytes, respectively. Average spiked recoveries in blank polypropylene packaging and food simulants were in the range of 80.4-99.5% and 75.2-106.7%, with relative standard deviations in the range of 0.9-9.1% and 0.2-9.8%. Dissolving the polypropylene food packaging with toluene and precipitating by methanol was demonstrated more effective than ultrasonic extract with acetonitrile or dichloromethane for extracting the additives. The method was successfully applied to commercial polypropylene packaging determination, Irgafos 168 and UV-P were frequently found in six commercial polypropylene films, and the content ranged from 166.47 ± 5.11 to 845.27 ± 29.31 μg g −1 and 2.10 ± 0.29 to 19.23 ± 1.26 μg g −1 , respectively.

“…With the good advantages of this method, it had appeared as proposed Method 3545 in Update III of the US EPA SW‐846 Methods soon after it was first described in 1995. There are also numerous different studies using ASE to extract polycyclic aromatic hydrocarbons (PAHs) , polychlorinated biphenyls (PCBs) , lutein, alkaloids , steroid and lipids , essential oils , and other nutraceuticals from foods, environmental samples, and herbal plants.…”

Sample preparation is the most time-consuming and laborious procedure during analysis. The rapid and effective extraction of solid and semi-solid samples is much more difficult than that of gas and liquid samples. In the present review, various extraction methods for solid and semi-solid samples such as supercritical fluid extraction, ultrasound-assisted extraction, microwave-assisted extraction, etc. are summarized based on the principles of field and field synergy effects. The expected trends of field-assisted extraction methods are discussed and proposed to encourage further development on the rapid and effective extraction for solid and semi-solid samples.
