The food processing industry faces the major challenge of ensuring optimal surface hygiene while simultaneously improving process efficiency. The OREGANO project aims to create innovative metallic surfaces with a dual antimicrobial effect. This effect is achieved through the covalent grafting of arylbenzothiazole derivatives with biocidal properties, and through surface microstructuring that prevents the formation of bacterial biofilms. The project comprises several components: synthesis of new compounds, evaluation of their antimicrobial properties (using in vitro and in silico approaches) and cytotoxicity, grafting (chemically or electrochemically) onto surfaces, and inkjet printing technologies for microstucturation.
Kinetic study of biocide effect in nanocellulose_based food film
This project will study the kinetic of biocide effect of a nanocellulose-based film food. The main aim is to graft Ag and/or ZnO NPs on and inside halloysite particles that have a characteristic shape of twisted sheets and therefore could acting as NPs tanks. The localization of NPs outside halloysite could induce a fast biocide effect with limited duration whereas the internal grafting could produce longer biocide effect. This project gathers all steps from the film food synthesis, its nanocharacterization to the evaluation of its toxicological effect on bacteria. The final goal is to find one or many halloysite functionalizations allowing to extend the biocide effect in film food and to transpose it to other types of materials.
