Since 2003, the Food and Agriculture Organization of the United Nations (FAO) has recognized the potential use of edible insects for food and feed and has supporteda line of topics related to edible insects. Jamaican field crickets (Gryllus assimilis) belong among the most promising edible insect species for production as food or feed. Crickets are generally artificially reared on the dried substrates, when soybean is used as a major protein component. In this study, we aimed to evaluate the effect of replacement of soybean meal by rapeseed meal, the by-product from oil production. The...

Tomato cultivation plays a central role in global fruit and vegetable production, providing consumers with a rich source of phytochemicals and health-beneficial nutrients. Food quality and safety represent the current duality that the food industry must address, ensuring that products contain significant amounts of nutrients and bioactive compounds, and comply the maximum allowable levels of chemical and biological contaminants. The overall quality and safety characterization of products is essential to ensure that they meet the required standards and regulations, ultimately safeguarding the...

The French Total Diet Studies (TDS) conducted by ANSES aims to monitor the exposure of several population groups to hundreds of chemicals through their food consumption. The second edition of TDS pointed out for example a dozen substances (including dioxins, PCBs, acrylamide, lead and arsenic) for which a health risk due to food contamination could not be excluded. In order to inform consumers more comprehensively about this dietary exposure and to improve risk-based official controls of food by authorities, there was a need to explore easily the collected data for identifying potential...

Polyethylene terephthalate (PET) is among the most common food contact materials (FCMs). Concerns about the nonintentionally added chemicals (NIAS) present in FCMs that can arise during polymerization have grown over the past few years. Specific migration restrictions for PET cyclic oligomers, which are considered as NIAS, have not yet been established by EU legislation. However, due to the lack of toxicological knowledge, their impact on human health is still unclear. Additionally, in silico calculations and evaluation of the Toxicological Threshold of Concern (TTC) established by the...

Plastics were revolutionary inventions that symbolized globalization and the interconnection of economies between countries in the second half of the 20th and the early of the 21st centuries. They are widely used in various industrial sectors including food packaging, construction, automotive, electronics, textiles, household items, and toys, with the current global production reaching over 370 million tons per year. These synthetic materials are made of an organic polymer matrix and chemical additives. In total, more than 10 000 additives were identified in plastics and over 2 400 are...

Due to constant pressure from consumers and authorities to reduce fossil-based plastic, the food contact materials (FCM) industry is forced to develop alternative materials. While these alternative materials need to be environmentally friendly, they must also be safe for consumers. In this study, we aim to determine if and to what extent trace elements could be released from these alternative materials. In this study, 100 samples representing different materials were collected: paper analogues (bagasse, wheat), wood analogues (bamboo, palm leaves, coconut, straw, wheat), bioplastics,...

Staphylococcal food poisoning outbreaks (SFPO) are caused by the ingestion of food contaminated with staphylococcal enterotoxins (SEs) produced by strains of Staphylococcus aureus (S.aureus) . To date, 33 SEs are described in the literature but only 5 classical toxins (SEA to SEE) can be routinely detectable via commercially available immunoassays (EN ISO 19020). Liquid chromatography coupled to mass spectrometry (LC-HRMS) approach is highly specific and allows the analysis of a wide range of toxins comparing with immunoassays. In this work, we propose to develop a Multiplex method by LC-MS...

Dithiocarbamates (DTC), a class of broad-spectrum fungicides, are among the most frequently detected pesticides in the European Union, often with Maximum Residue Level (MRL) exceedances, due to their extensive use over the past decades. DTC have a polymeric structure composed of one or more metallic cations coordinated to an organic ligand whose structure allow the classification of DTC into three main groups : propylene-bis-dithiocarbamates (i.e. propineb), ethylene-bis-dithiocarbamates ( i.e.maneb, zineb, nabam, metiram, mancozeb) and dimethyl-dithiocarbamates (i.e. thiram, ziram, ferbam)....

To ensure food safety, European regulations require the monitoring of chemical contamination of foodstuffs of animal origin. This monitoring is based on a range of analytical methods capable of detecting, in particular, residues of veterinary treatment products, in order to implement national control plans. In this context, a method for monitoring Non-steroidal anti-inflammatory drugs (NSAIDs) in porcine muscle by LC-Mass spectrometry was developed for the determination of 22 target substances, including metabolites, at concentration in line with regulatory limits. Non-steroidal...

Dithiocarbamates (DTC) are one of the most largely used fungicides in agriculture as they are cost-effective against a broad spectrum of fungi and plant diseases. DTC are highly instable and they tend to decompose in foodstuffs matrix into ethylene-thiourea (ETU) and propylene-thiourea (PTU). Currently, these contaminants are determined using organic-based mass spectrometry techniques (MS or MS/MS) coupled to high performance liquid chromatography (HPLC). Due to the sulphur (S) moiety in their structure, they can also be determined using inorganic based MS techniques such as inductively...
