Reliable bioassays to detect potential hazard of paperboard food contact material extracts

Food contact materials (FCM) represent a major economic issue and a large field of innovation. Food packaging production must be in compliance with the European Regulation 1935/2004: the third article specifies that FCM must not transfer their constituents to food in quantities which could endanger human health under normal or foreseeable conditions of use. Indeed, these materials are not inert and, in addition to started substances, Non-Intentionally Added Substances (NIAS) are able to be released into the food. NIAS can be contaminants from recycled materials, impurities, synthetic residues, new substances formed along the packaging production chain… Then, NIAS could represent a larget pa…

In vitro hazard assessment of nanoparticles developed for biomedical applications

Nanotechnology is a growing sector in industry for twenty years and nanomaterials are currently used in numerous industrials applications. Their interest is based on their dimensions and their shape that give them very particular technological and biological properties. However, the development of these nanoparticles, their industrial preparation and integration into various products already involve an initial increased of human exposure (via inhalation, percutaneous and oral route). Another exposure pathway exists and is represented by drug injections. The risks associated with these new technologies and new products are still unclear. After a characterization step (zeta potential, TEM, TG…

Extraction d'éléments traces métalliques à partir de pains libanais et évaluation du danger de ces mélanges

Parmi les éléments traces métalliques (ETM) qui peuvent être présents dans les aliments, certains sont connus comme étant toxiques et doivent faire l’objet d’une surveillance accrue. En ce qui concerne la sécurité sanitaire, il semble pertinent d’étudier le cas du pain, qui représente une part majoritaire de la ration journalière de la population libanaise. Dans une étude précédente, l’Institut de Recherche sur l’Agriculture Libanaise (IRAL) a déterminé la présence de plusieurs ETM (arsenic, cadmium, cobalt, chrome, mercure, nickel et plomb) dans le pain libanais. Bien que la toxicité de chaque ETM soit connue individuellement, il est important de tester la toxicité de ce mélange d’ETM, pré…

Salivary proteome and sensitivity to bitterness

Among the various factors that dictate food choices, the sensorial acceptability and the in-mouth perception of food are essential. For example, bitterness is partly responsible for the rejection of some vegetables by some consumers. In this study, the aim is to evaluate if the salivary environment of an individual plays a role in his sensitivity to bitter taste
