“…1,2 However, antioxidants can migrate from the plastics into the food and contaminate it during production or storage, potentially giving rise to issues of food safety. 3,4 These chemicals could potentially endanger human health, and thus the antioxidant additives in polymers need to be identified and quantified for quality control. [5][6][7][8] To date, mass spectrometry has been broadly applied in analyses of additives, including gas chromatography-mass spectrometry, 9,10 high-performance liquid chromatography coupled with mass spectrometry, 11 real-time mass spectrometry (DART-MS), 12 atmospheric solid probe with quadrupole time-of-flight mass spectrometry 13 and matrix-assisted laser desorption/ionization mass spectrometry.…”

Mass spectrometry has been applied to the targeted analysis of commonly used additives (such as Irganox 1010, Irganox 1076, Irgafos 168 etc.) in plastic materials, but a fast and straightforward method for the non-targeted identification and quantification of unusual or potentially new antioxidant additives is still unavailable. In this study, a novel and simple method for the identification and quantification of unknown antioxidant additives in plastic food packaging using ultrasonic extraction and ultra-performance liquid chromatography , r 2 > 0.99). The accuracy of the method has been tested by relative recovery experiments with spiked samples, with results ranging from 94.3% to 104.8%, and the precision (relative standard deviation) was within 11.0% (n = 3).Finally, the method has been successfully applied to the determination of antioxidants in several real plastic samples.

“…In fact, an antioxidant should be chemically able to interfere with the oxidation reactions, and should resist its own degradation during film manufacturing as well as its loss by migration to the matrix surface and subsequent possible contamination of the contact matter 21. This point is of particular relevance in the case of additives for plastics used for food packaging 22–24. Indeed, European legislation regulates migration from food‐contact materials, such as packaging, into foods by an overall migration limit applicable to the total of the migrating material and specific migration limits referring to individual substances or groups of substances 24…”

Several novel random copolymers of ethylene and 1-olefin counits bearing a highly efficient phenolic antioxidant moiety placed at different distances from the polymerizable double bond were prepared in the presence of a metallocene catalyst. These copolymers were meltblended with an antioxidant-free LDPE in an internal batch mixer to obtain innovative materials containing nonreleasing polymeric antioxidants suitable for safer food packaging applications. Blends and films, obtained by compression molding, were tested for their thermal and thermo-oxidative stability by thermogravimetric analysis both in dynamic and isothermal conditions. Films containing the macromolecular antioxidants showed a longer induction time before O 2 uptake starts and, consequently, a higher degradation temperature than neat LDPE or LDPE containing a low molecular weight commercial additive. Aging tests demonstrated that the new polymeric antioxidants also exert a valid protection against photo-oxidation. Eventually, migration tests demonstrated the absence of any trace of products containing the antioxidant moiety when the films were kept in contact with a food simulant.

“…Several types of antioxidants can be used to prevent the aging of plastic, such as phenolic antioxidants, organophosphorus compounds and different amines. However, antioxidants can migrate from the plastics into the food and contaminate it during production or storage, potentially giving rise to food safety issues [78,79]. Antioxidants are used in almost all commercial polymers in small amounts up to 2% (w/w) (20,000 mg/kg or ppm) [16].…”

The intensive use of plastics and derivatives during the last century has increased the contamination of animal habitats. The breakdown of these primary plastics in the environment results in microplastics (MP), small fragments of plastic typically <1-5 mm in size. Apart from the potential negative effects of the MPs per se, it is generally assumed that microplastics may increase the exposure of marine aquatic organisms to chemicals associated with the plastics. In addition, to enhance the performance of plastics, additives are added during manufacture. Furthermore, they are active in absorbing other contaminants and be used as vectors of highly and well-documented persistent contaminants. Finally, these small MPs are easily ingested by animals and affect their physiology and behaviour. Thus, aquatic living organisms are continuously exposed to these MPs, and associated contaminants, and could suffer from its contamination but also introduce them into the food chain.
