“…[ 1,12,18,20 ] Migration of diisopropylnaphthalene – DIPN – from recycled paper and paperboard packaging has been also measured in several studies. [ 1,21 ] The source of DIPN is the incorporation of recycled office paper into food packaging since DIPN is employed as solvent in carbonless copy paper, which has replaced formerly used polychlorinated biphenyls.

Since paper recycling operates with market‐collected paper scrap, this may lead to undesirable chemicals migrating from the wastepaper into the recycled material. Therefore, this study is based on the assessment of several additives inadvertently included in cellulose packaging that may migrate to foodstuff, considering that toxicological effects of some of these additives may persist in recycled cellulose fibers used to produce new food packaging. The purpose of this study is to determine migration of dibutyl phthalate (DBP), diisobutyl phthalate (DIBP), bis(2‐ethylhexyl) phthalate (DEHP) and 2,6‐diisopropylnaphthalene (DIPN) into fatty food simulant (n‐heptane) by means of gas chromatography with flame ionization detector (GC‐FID). For this purpose, commercial samples of cellulose food packages are contaminated with different concentrations of these additives, and migration into the food simulant is evaluated after the samples remain in contact with the food simulant for a prolonged time at maximum temperatures of 40 °C. The results of the assessment show that an amount ranging from 0.1–0.3% of phthalates and DIPN migrate from the fortified package into the fatty food simulant. The maximum levels of migration of these additives into the recycled cellulose packaging in order to comply with the specific migration limits for contact with foodstuff have been estimated.

“…Sample preparation constitutes a crucial integral part of the safety assessment of paper and cardboard FCMs, as it highly influences the outcome of the subsequent analysis. Loss of relevant FCCs (Wagner & Oehlmann, 2011), systematic errors (Souza‐Silva et al., 2015), and external contamination of samples (Chevolleau et al., 2016; Giannetti et al., 2017) are recognized among the challenges derived from sample preparation procedures. Those can affect the efficiency, reliability, and reproducibility of the subsequent safety assessment.…”

“…For the safety assessment of paper and cardboard FCMs and FCAs, an absence of a harmonized EU regulatory framework is encountered that would ideally provide standardized guidelines (Giannetti et al., 2017; Schilter et al., 2019). However, EN protocols are encountered for sample preparation including EN 645:1993 for cold water extractables, EN 15519:2007 for hot water extractables, EN 15519:2007 for organic extractables, and EN 14338:2003 for the determination of FCCs migration from paper to poly(2,6‐diphenyl‐p‐phenylene oxide), commercially Tenax (Schilter et al., 2019).…”

“…Extraction practices involve headspace‐solid phase micro extraction (Canellas et al., 2010; Sanchis et al., 2017) and purge‐and‐trap methods (Bengtström et al., 2014) for the extraction of volatiles. For the extraction of nonvolatile substances, immersion (Biedermann & Grob, 2013a), Soxhlet extraction (Bengtström et al., 2014), reflux distillation (Ozaki et al., 2004), and automated accelerated solvent extraction (Giannetti et al., 2017) have been employed. For such approaches, the involvement of a polar and a nonpolar solvent is proposed for the holistic extraction of chemicals contained in the FCM.…”

“…Sample contamination by external contaminants during sample preparation can occur and interfere with the chemical analysis and in vitro bioassays. Active components present in the lab equipment or alkylphenols or phthalates often present in plastic lab ware can be sources of external contamination (Chevolleau et al., 2016; Giannetti et al., 2017). This may result in the analysis of chemicals, which are not originally present in the FCM, and possibly overestimation of FCCs presence and levels in the FCM in chemical analysis.…”

In the European Union (EU), Regulation (EC) 1935/2004 provides a harmonized legal EU framework and sets out the general principles for safety and inertness for all Food Contact Materials (FCMs) and Food Contact Articles. From a food safety point of view, however, specific EU legislation for paper and cardboard FCMs is lacking, while at Member State level, national legislation differs among countries. More than 11,000 chemicals have been identified in all types of FCMs, most of them without any information on toxicity or migration potential from FCM to food. The present review shows a wide variability of protocols, approaches, and conditions used in scientific studies, which are difficult to compare. In this regard, procedures and conditions laid down in EU legislation for plastics and European Standards (EN protocols) may serve as a good basis for the future sample preparation procedures in the framework of paper and cardboard FCMs safety assessment. Challenges on sample preparation procedures are presented involving the interlinked steps of sample preparation, conditions used and their impact in chemical analysis and in vitro bioassay testing. Currently, there is no general consensus on the criteria for structuring, evaluating, and tuning sample preparation procedures for paper and cardboard FCMs. For this purpose, a set of modified criteria and a decision tree are proposed based on the literature. Along this, mass transfer processes occurring in paper and cardboard FCMs and parameters affecting chemical migration need to be accounted for prior to reaching general consensus on criteria for sample preparation procedures.

The present work is part of a comprehensive study aiming to identify and quantify an array of harmful contaminants at very low concentrations in recycled paperboard materials intended for food contact applications. In this initial study, three commonly used extraction techniques were optimized and tested for their efficacy and accuracy in isolating 13 polycyclic aromatic hydrocarbons (PAHs) from three commercially available food packaging materials made from recycled paperboard. The techniques were Soxtec extraction (SE), ultrasound-assisted extraction (UAE), and headspace solid-phase microextraction (HS-SPME), followed by gas chromatography-mass spectrometry (GC/MS) analysis. The recoveries of all three methods were rather satisfactory; 10 out of 13 substances were recovered at rates between 70 and 124% using the SE method, 8 out of 13 substances were recovered at rates between 50 and 134% using the UAE method, and finally, 8 out of 13 substances were recovered at rates between 70 and 105% using the HS-SPME method. Regarding accuracy, the HS-SPME method gave the best results at 125 μg kg−1, as 7 out of 13 concentration values were within acceptable limits, while only five and four concentration values were within limits for the UAE and SE methods, respectively. Furthermore, the results of both the calculated RSD and HorRat values indicated that HS-SPME is more accurate for extracting PAHs than the other two methods.
