Use of reliable bioassays to detect potential hazard of food contact materials extracts to ensure quality, safety and innovation of paperboards
2015
International audience; Food contact materials (FCM) represent a major economic issue and also an important field of innovation for packaging industries. Food packaging production must currently meet manufacturing good practices, safety for human health and thus be in compliance with the article 3 of the European Regulation 1935/2004: “Material and articles in contact with food do not transfer substances in amounts which could endanger human health…”.
Liquid chromatography‐Orbitrap Tribrid high‐resolution mass spectrometry using data dependent‐tandem mass spectrometry with triple stage fragmentatio…
2021
A new, fast, and automatic approach has been applied for the tentative identification of unknown substances released by food contact epoxy resin after performing a migration test with food simulant. This approach combines intelligent data acquisition with AcquireX linked to liquid chromatography-Orbitrap Tribrid high-resolution mass spectrometry using data dependent-tandem mass spectrometry with triple stage fragmentation coupled to Compound Discoverer™ software for automated data processing and compound identification. The identification of the observed features was performed using a set of identification criteria, including exact mass, isotope pattern, tandem mass spectrometry spectra mat…
Recent European Food Safety Authority toxicological evaluations of major phthalates used in food contact materials
2009
During the 1980s and 1990s, and at the EU level, the Scientific Committee for Food evaluated a number of phthalates that were being used, or were requested for use, as additives in plastics. At this time, peroxisome proliferation was considered as the pivotal effect on which toxicological evaluation of these chemicals was based. At the end of 1990s, a general consensus has been agreed that rodents are highly sensitive to the phenomenon of peroxisome proliferation and that this particular effect should not be used for human risk assessment. Consequently in 2004, it was requested from the newly created European Food Safety Authority to perform a new evaluation of the mainly used phthalates on…
An overview of nanoparticles role in the improvement of barrier properties of bioplastics for food packaging applications
2017
Abstract Plastics are the most demanding materials for the food packaging industry due to economical and practical reasons such as their low cost, lightness, easy to handle in integrated production lines, and their higher resistance than other materials. Besides containment and information, the packaging should protect foodstuffs from not only contamination but also the loss of food quality. Despite the many advantages, their inherent permeability is perhaps the foremost drawback that could lead to the loss of some food components and, also, to the transference of gases or moisture from the surrounding to the food. Thus, the barrier properties and the wettability are of fundamental importan…
Nanomaterials in Food, Which Way Forward?
2012
Abstract Nanotechnology has emerged as one of the most innovative technologies occurred in decades and has the potential to improve food quality and safety. At present, there are also a few studies demonstrating that nanomaterials (NMs) are not inherently benign. This chapter highlights some current applications of NMs in food, food additives and food contact materials and reviews analytical approaches suitable to address food safety-related issues of nanotechnology. As starting point, discussion on the current regulatory situation of nanotechnology in relation to food is addressed, followed by a detailed description of sample preparation aspects, separation methods (e.g. field-flow fractio…
Exploiting redox activity of MIL-100(Fe) carrier enables carvacrol prolonged antimicrobial activity
2021
The design of efficient food contact materials that maintain optimal levels of food safety is of paramount relevance to reduce the increasing foodborne illnesses. In this work, we develop a smart composite MOF-based material that fosters a unique prolonged antibacterial activity. The composite is obtained by entrapping a natural preserving food molecule, carvacrol, into the mesoporous MIL-100(Fe) material following a direct and biocompatible impregnation method and obtaining particularly high payloads. By exploiting the intrinsic redox nature of MIL-100(Fe) material it is possible to achieve a prolonged activity against E. coli bacteria due to a triggered two-step carvacrol release of films…
Non-target and suspected-target screening for potentially hazardous chemicals in food contact materials: investigation of paper straws
2020
A non-target screening strategy was developed for the safety evaluation of potentially hazardous chemicals in paper food contact materials (FCMs). A tentative list of suspect analytes was generated using publicly available FCM substance inventories, the presence of contaminants in paper straws was confirmed by high-resolution Orbitrap mass spectrometry. Data-independent and data-dependent MS and MS/MS results for candidate compounds were processed using a workflow including peak detection by deconvolution, blank subtraction, retention time alignment, formula assignment and fragmentation spectra search against spectral libraries followed by
Test procedures for obtaining representative extracts suitable for reliable in vitro toxicity assessment of paper and board intended for food contact.
2009
International audience; This paper describes the use of a suite of extraction procedures applicable to the assessment of the in vitro toxicity of paper/board samples intended for food-contact applications. The sample is extracted with ethanol, water, or exposed to modified polyphenylene oxide (Tenax) for fatty, non-fatty and dry food applications, respectively. The water extracts are directly suitable for safety assessment using in vitro bioassays. The ethanol extracts of the paper/board and of the exposed Tenax require pre-concentration to give acceptable sensitivity. This is because the in vitro bioassays can tolerate only a small percentage of added organic solvent before the solvent its…
Safety Evaluation of Food contact paper and board using Chemical Tests and in vitro Bioassays-The role of known and unknown substances
2010
International audience; In vitro toxicological tests has have been proposed as an approach to complement the chemical safety assessment of food contact materials, particularly those with a complex or unknown chemical composition such as paper and board. An EU 5th framework program project “BIOSAFEPAPER – Application of bioassays for safety assessment of paper and board for food contact” specially focused on the application of biotests to paper and board. The project included both chemical characterization and toxicological testing of a representative number of paper and board extracts prepared according to the proposed end use (wet, fatty and dry food contact). Among the concerns addressed …
Determination of 60 Migrant Substances in Plastic Food Contact Materials by Vortex-Assisted Liquid-Liquid Extraction and GC-Q-Orbitrap HRMS
2021
A GC-HRMS analytical method for the determination of 60 migrant substances, including aldehydes, ketones, phthalates and other plasticizers, phenol derivatives, acrylates, and methacrylates, in plastic food contact materials (FCM) has been developed and validated. The proposed method includes migration tests, according to Commission Regulation (EU) 10/2011, using four food simulants (A, B, C, and D1), followed by vortex-assisted liquid–liquid extraction (VA-LLE) and GC-Q-Orbitrap HRMS analysis in selected ion monitoring (SIM) mode, with a resolving power of 30,000 FWHM and a mass accuracy ≤5 ppm. The method was validated, showing satisfactory linearity (R2 ≥ 0.98 from 40 to 400 …
