“…This work is further evidenced by Oldring et al who worked on a model to estimate BPA-diglycidyl ether exposure, concluding that exposure for UK consumers was well below the tolerable daily intake for all derivatives. 17 With BPA non-intent (BPANI), migration studies have been carried out on coatings of similar chemistry, 18,19 as is common with all new coating formulations, with a multitude of analytical techniques used such as gas chromatography and mass spectrometry. 20 While these methods of interaction are relatively well reported, the effect of the simulant solution/foodstuff on the adhesion of a coating to the substrate, or the substrate itself post-retort, has not been reported in depth.…”

Food packaging simulant failure mechanisms in next generation steel packaging

Legislative pressures have led to the mature dominant chromium-coated steel (ECCS) substrate and epoxy phenolic lacquer replacement in Europe. An investigation was carried out to examine the interaction between a steel surface engineered with a novel, developmental substrate coated using Cr (III)-based electrolytes and the food stuff being canned. Samples of lacquered material were subjected to a typical retort process (121°C for 90 minutes) and examined using a variety of laboratory analytical techniques. The foodstuff being packaged has a significant impact on the substrate/lacquer adhesion with clear differences in failure mechanisms between foodstuffs. There is clear evidence of chemical species transfer through the next generation lacquer, and this can instigate corrosion at the surface where incomplete chromium coverage leads to exposed iron. In general, the novel developmental material exhibits lower adhesive properties and shows a greater sensitivity to the foodstuff, although this is largely attributed to the homogeneity of the coverage. The novel substrate proves to be a promising alternative to ECCS due to REACH legislation, but improvement is required to achieve equivalent performance.

“…Epoxy‐based resins currently dominate the market for can coatings, occupying an estimated 95% of market shares as of 2013 (Geueke, 2016). The most common type is synthesized with bisphenol A (BPA) and epichlorohydrin to form bisphenol A diglycidyl ether epoxy resins, though epoxy resin blends containing amines, acrylates, anhydrides, or phenolics are also options on the market (Geueke, 2016; Paseiro‐Cerrato, MacMahon, Ridge, Noonan, & Begley, 2016). Toxicological concerns and consumer backlash have spurred a search for alternatives to BPA, with acrylic and polyester materials being potential replacements and coatings composed of polyolefins or non‐BPA epoxies currently under development (Geueke, 2016).…”

The presence of chemical contaminant in alcoholic beverages is a widespread and notable problem with potential implications for human health. With the complexity and wide variation in the raw materials, production processes, and contact materials involved, there are a multitude of opportunities for a diverse host of undesirable compounds to make their way into the final product-some of which may currently remain unidentified and undetected. This review provides an overview of the notable contaminants (including pesticides, environmental contaminants, mycotoxins, process-induced contaminants, residues of food contact material [FCM], and illegal additives) that have been detected in alcoholic products thus far based on prior reviews and findings in the literature, and will additionally consider the potential sources for contamination, and finally discuss and identify gaps in current analytical strategies. The findings of this review highlight a need for further investigation into unwanted substances in alcoholic beverages, particularly concerning chemical migrants from FCMs, as well as a need for comprehensive nontargeted analytical techniques capable of determining unanticipated contaminants.

“…The identified migrants were mostly derived from diols, namely, diethylene glycol (DEG), ethylene glycol (EG), and neopentyl glycol (NPG), and diacids like adipic acid (AA), isophthalic acid (IPA), and phthalic acid (PA). Several cyclic oligoesters also have been reported from migration studies of polyester‐based can coatings, bottles, and trays . Though the available data on cyclic oligoesters are not exhaustive, all previously conducted studies indicate that a wide variety of cyclic oligoesters are pervasive migrants from polyester‐PU or polyester polyol‐PU packaging materials.…”

Migration studies and chemical characterization of low molecular weight cyclic polyester oligomers from food packaging lamination adhesives

Laminate structures are widely used for food packaging applications. Polyester urethane‐based adhesives are very common materials for bonding the layers of such laminates together. Unintended by‐products of polyester synthesis include low molecular weight cyclic polyester oligomers (cyclic oligoesters) that lack the required hydroxyl functionality to react with isocyanates to form the intended high molecular weight polyurethane polymer and remain as impurities with high migration potential. Our investigation conducted migration studies of 537 commercial and/or developmental food packaging laminate structures by using food simulants with gas chromatography‐mass spectrometry analyses of the extracts. A subset of the extracts were also analysed by high‐performance liquid chromatography‐mass spectrometry and gas chromatography‐mass spectrometry with chemical ionization. Migration of cyclic oligoesters of diverse chemical structure was observed in nearly all of the samples analysed. Aside from migrants originating directly from polyolefin sealant films on the food‐contact side of the laminates, cyclic oligoesters were the migrants detected at next highest concentration. This report presents electron ionization mass spectra and molecular structures of 106 cyclic oligoesters including a series of novel as well as previously identified species. Fifty‐six cyclic oligoesters migrated from the 537 laminate samples analysed were evaluated for frequency of occurrence and migration concentration range. The most commonly observed cyclic oligoester migrants were those derived from combinations of the polyhydric alcohols, diethylene glycol, and neopentyl glycol and the dibasic acids, adipic, and phthalic/isophthalic.
