Evaluate the Link Between the Characteristics of Oral Physiology and the Formation of the Food Bolus During the Consumption of Dairy Products in Elderly People (AlimaSSenSLait)

Evaluate the Link Between the Characteristics of Oral Physiology and the Formation of the Food Bolus During the Consumption of Cheese Products in Elderly People

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Good chewing ability
Other: Two samples of saliva
  1. Without stimulation: the first will be used to measure the flow of naturally secreted saliva
  2. With stimulation: the second will will be used to measure the flow and viscosity of the saliva secreted after stimulation
Other: Chewing behaviour
Measure the time taken by subjects to chew the food and the number of bites they use before swallowing
Other: Study of the food bolus
  • Analysis by a compression and viscosity test
  • Evaluation of the quantity of saliva incorporated by drying
Experimental: Impaired chewing ability
Other: Two samples of saliva
  1. Without stimulation: the first will be used to measure the flow of naturally secreted saliva
  2. With stimulation: the second will will be used to measure the flow and viscosity of the saliva secreted after stimulation
Other: Chewing behaviour
Measure the time taken by subjects to chew the food and the number of bites they use before swallowing
Other: Study of the food bolus
  • Analysis by a compression and viscosity test
  • Evaluation of the quantity of saliva incorporated by drying
