Protein Digestion Studies

We are currently working to explore how various types of proteins and food processing techniques alter protein digestibility. We are also interested in studying protein digestion in groups with lower digestive function, including infants, the elderly and people with gastrointestinal disease. We are examining how increased protein survival to the colon leads to increased microbial protein digestion (putrefaction) and the resulting toxic metabolites and gut inflammation. We are currently modelling infant digestion of milk proteins in a piglet model. With a collaborative approach, we are assessing digestion and putrefaction via peptidomics, metabolomics, microbial sequencing and inflammatory protein analysis.
