Impact of mastication on the gastric digestion of frankfurters : case of elderly

Résumé

This work was designed to evaluate the impact of deficient food oral processing and aging digestive conditions on a model food: frankfurters. Food boluses were prepared for normal mastication or deficient chewing by programing a mastication simulator (AM2). Gastric digestion was simulated using a dynamic in vitro digester (DIDGI®) of adult and elderly physiological conditions. Lipids, proteins and peptides kinetic release were assessed by Infrared spectroscopy. We observed a low impact of chewing on normal gastric digestion, mainly compensated by the activity of gastric enzymes and the acidic conditions. However, in elderly digestive conditions, a delay in release of macronutrients with a less extent occur. This study can be considered as a proof of concept with a purpose for developing specific food for elderly, adapted to their ability for oral processing and digestive physiology.
