Filter by:The aim of this study is to understand how dairy products enriched in minerals and proteins are broken down in the mouth. More specifically, investigators wish to evaluate the link between oral physiology (salivation and mastication) and formation of the food bolus during the consumption of enriched cheese, that is to say the way in which the food is broken down to be swallowed. The study will take place at the INRA in Dijon during 2 one-hour sessions spread over 4 months. These two sessions will allow investigators to characterise the chewing behaviour of the subjects and their salivation, and the structure of the food bolus formed when eating the four products of the project. For each of the four foods in each session: - Two samples of saliva will be taken - A video will be made of subjects eating one of the study products - Subjects will chew the study foods and spit them out.
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: - Two samples of saliva will be taken - A video will be made of subjects eating Sponge cake or Brioche - Subjects will be trained in exercises for the following sessions - this will consist in chewing the study foods and spitting them out on the experimenter's signal. During the 6 other sessions, subjects will be asked to: - Chew one of the study foods and spit it out on the signal of the experimenter. - Evaluate the mouthfeel while eating Sponge cake or Brioche by answering different questions. This test will be done during 4 of the 6 sessions.
