Materials and methods
5
• Honey: sunflower honey from « la miellerie des Fontenelles », Vendée, France ; treated in the ONIRIS laboratory by the Honey Split Process (HSP).
• Panel: 60 people*, 70% women and 30% men, 67% between 18 and 25 years old, 15% between 26 and 35 years old, 2% between 36 and 45 years old, 10% between 46 and 65 years old.
• Analysis: seven sessions of 45min each in the ONIRIS sensory analysis room, on January 27th 2012.
*minimal number of participants needed to ensure statistical validity of the study according to the French norm AFNOR XP V09-501
