Bioavailability and Metabolisation  
A gastrointestinal dialysis model was developed in the Laboratory of Nutrition and Functional Food Science. This model with an initial gastric stage, followed by an intestinal stage and a colonic-phase is much faster, less expensive and easier to perform compared to in vivo tests, and helps in resolving the mechanism of metabolisation and the identification of the metabolites of active compounds, in combination with LC-MS and LC-NMR techniques.
