Researchers at INRAE have developed an artificial mouth to reproduce and better understand the processing of soft foods. The device is based on anatomical data collected at the Fujita Health University and features a silicone tongue that contracts using compressed air to mimic the movements of the human tongue. The results were published on October 15 in the journal Scientific Reports.
With a rising world population and ageing demographics, one of the challenges for the food industry is to be able to offer innovative products meeting the needs of people suffering from age-related pathologies, such as sarcopenia or problems with salivation or swallowing.
Current in vitro models do not always accurately reproduce the anatomy of the mouth or tongue movements and are therefore of limited help when developing food tailored to the specific needs of different populations.
In this context, researchers from INRAE and their Japanese counterparts at Fujita Health University have collaborated to design the first artificial mouth with a tongue that can be programmed to simulate the contractions and movements observed in vivo. The tongue is made from a silicone designed to reproduce the elasticity, wettability and roughness of the human tongue. It includes three cavities that can be inflated and deflated by compressed air to accurately reproduce the movements observed in humans via ultrasound imaging.
