Multi-actor research projects are still a recent trend, putting at work together researchers with non-academic partners,like representants of food chain actors. The INTAQT project (INnovative Tools for Assessment and Authenticationof chicken meat, beef and dairy products’ QualiTies) has chosen to play the game fully: the project was set up withstakeholders’ consultations at the heart of the project and with their recommendations implemented in the research.Stakeholders from the beef, dairy or poultry sectors in seven European countries are involved from producers toretailers, including processors and other relevant actors in each context. They were consulted at three levels: firstthrough individual qualitative interviews then invited to national group discussions and some of them to Europeangroup meetings. Their role was to give their opinions and suggestions for the choice of farming systems to be studiedin the project and on the choice of quality criteria to take into account and on analysis to be conducted. They will beinvolved all along the project life with their contribution next year to the co-construction of the multi-criteria scoringtool. This presentation is based on analysis of interviews with the project’s Work Package leaders and Task Leadersin order to confirm or refute the following hypotheses: (1) there was an a priori reticence of some of the researchersabout the importance and relevance of including stakeholders’ voices in a research project; (2) after almost of 2 yearsin the process, there is an interest in the world of research, but also difficulties in effectively integrating positionsthat are difficult to reconcile (temporality, decision-making methods, governance, etc.). Globally we reflect on howmulti-actor approach like the one in INTAQT questions a research project.
