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 Authentication of chicken meat, beef and dairy products’ QualiTies) has chosen to play the game fully: the project was set up with stakeholders’ 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 to retailers, including processors and other relevant actors in each context. They were consulted at three levels: first through individual qualitative interviews then invited to national group discussions and some of them to European group meetings. Their role was to give their opinions and suggestions for the choice of farming systems to be studied in the project and on the choice of quality criteria to take into account and on analysis to be conducted. They will be involved all along the project life with their contribution next year to the co-construction of the multi-criteria scoring tool. This presentation is based on analysis of interviews with the project’s Work Package leaders and Task Leaders in order to confirm or refute the following hypotheses: (1) there was an a priori reticence of some of the researchers about the importance and relevance of including stakeholders’ voices in a research project; (2) after almost of 2 years in the process, there is an interest in the world of research, but also difficulties in effectively integrating positions that are difficult to reconcile (temporality, decision-making methods, governance, etc.). Globally we reflect on how multi-actor approach like the one in INTAQT questions a research project.
