The aim of this study is to understand how foods such as Sponge cake or Brioche are broken down in the mouth. More specifically, investigators wish to evaluate the link between oral physiology (salivation and mastication) and (i) formation of the food bolus during the consumption of Sponge cake or Brioche, that is to say the way in which the food is broken down to be swallowed (ii) mouthfeel during the consumption of Sponge cake or Brioche, meaning the sensations that participant feel when they eat these products.
The study will take place at the INRA in Dijon during 7 one-hour sessions spread over 3 months. The first session will allow us to characterise the chewing behaviour of the subjects and their salivation, and will enable us to train them in the instructions for the following sessions. The 6 other sessions will allow us to study the structure of the food bolus while being formed and the mouthfeel of the foods in the project.
In the first session:
During the 6 other sessions, subjects will be asked to:
