Per- and poly-fluoroalkyl substances (PFAS) are applied to food packaging and other materials to provide fat, fire, and/or water resistance properties. Emissions of PFAS from industrial wastes lead to environmental contamination. These compounds are known as "forever chemicals" due to their stability and persistence. PFAS are expected to have carcinogenic and reprotoxic effects on humans. Every day, PFAS may come into contact with people through the environment, food, and water. In summer 2022, the European Union moved forward in the fight against PFAS contamination in food and feed [1-3]....

This work reports the development of a novel method based on single particle inductively coupled plasma-triple quadrupole mass spectrometry (ICP-QQQMS or ICP-MS/MS) using a high efficiency sample introduction system (HESIS) such as APEXTM for the characterisation of TiO2 (nano)particles (NPs) in food samples. The use of the mass shift detection mode (O2+H2 as a mixture reaction gas) avoids the isobaric interferences of 48Ca isotope hence allowing accurate characterisation of TiO2 NPs in complex matrices such the foodstuffs. APEXTM Ω proved to be an excellent approach to avoid matrix effects...

In the food industry, titanium dioxide (E171) is used as a coloring agent, opacifier or flavor carrier in foodstuffs or as a clarifying agent in drinks. In some common foods, a fraction (5 to 50 %) of this additive has been found with a size lower than 100 nm (1). This fraction, able to cross physiological barriers and then to be accumulated in systemic organs, may cause problems with the digestive system. Thus, EFSA has concluded this additive cannot be considered safe (2). As the toxicological effects depend mainly on the size and concentration of TiO2particles, the determination of these...

Following the opinion of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) on the risks associated with ingestion of food containing the food additive E171, French authorities suspended the use of this additive in food products from January 1st 2020 as a precautionary measure. Two years later Commission Regulation (EU) 2022/63 of 14 January 2022 banned the use of E171 as a food additive in the European Union. We report here the outcome of a 5-year screening (2018-2022) of 352 food samples collected on the French market by the French authorities and analysed...

Titanium dioxide (TiO2) is applied in food as a white pigment and listed as food additive E 171. EFSA's opinion [1] states that it is not certain that its use in food is safe because it may be genotoxic. Hence, the European Commission no longer allows E 171 [2]. Consequently, authorities need analytical methods to control the absence of E 171. Because most Ti occurs in food as TiO2, screening can be realized by analyzing the total Ti content as a measure (proxy) for TiO2. This study examined whether the concentrations of total Ti are (much) larger in food products containing E 171 than in...

In the last decades, our life style significantly changed, for instance in terms of consumption of convenient food or usage of single-use items. As a direct consequence, the production of plastics is globally increasing, as well as their release into the environment, threatening wildlife and human health. Most of the produced plastics are used for packaging items, from cosmetic to food applications. Up to now, the most common plastics used for packaging have been petroleum-derived, such as polyethylene (PE), polystyrene (PS), polyethylene terephthalate (PET), polyvinylchloride (PVC),...

The olive tree is an evergreen tree cultivated for thousands of years throughout the Mediterranean basin, which represents the largest international olive growing area. The European Union holds the record in terms of olives and olive oils production, consumption, and exportation. Extra virgin olive oils are particularly important for the national agroindustrial sector, for the aspects related to the production territory (authenticity), and for the link with the Mediterranean Diet. However, at the same time, because of economical purposes, it is also one of the products most subjected to...

This study reports the development and validation of a new analytical method for the simultaneous speciation analysis of Se and Hg in fish muscle. For this purpose, four Se species (Se(IV), Se(VI), Se-methionine/SeMet and Se-cysteine/SeCys) and two Hg species (Hg(II) and methylmercury/MeHg) were extracted simultaneously by microwave assisted enzymatic hydrolysis (using protease XIV at pH 7 ≈ and 2-mercaptoethanol) and then separated in less than 15 min by using a mixed mechanism anion-cation exchange HPLC with a mobile phase consisting of a mixture of methanol 5% (v/v), 45 mM HNO3, 0,015% 2-...

The quality of coffee is affected by the amount of oxygen present in the packaging. A maximum oxygen content is authorized to avoid oxidation of coffee during the shelf life, which would lead to off-taste in coffee cup. Oxygen content in the packaging can be measured by Fluorescent Decay, as described in ASTM F2714-08 (2021). However, this is only possible for transparent packaging. If it is not the case, direct sampling in the packaging is necessary. This requires a minimum amount of headspace in the pack. This minimum amount is defined by the oxygen sensor technology. In the case of...

Toxic elements are considered one of the major sources of pollution in the aquatic environment. Aquacultural produce may be introduced to hazardous toxic elements, such as arsenic (As) and mercury (Hg) in surface water due to domestic and industrial wastes. To ensure food safety and consumer protection of milkfish (Chanos chanos) products in the Philippines, toxic elements in milkfish are being tested by chemical testing laboratories. The reliability and accuracy of the method of these laboratories can be demonstrated thru the z-scores obtained in joining Proficiency Testing (PT) schemes....
