University of Limerick will investigate the presence of ‘anti-nutritional’ factors, which are a range of molecules that inhibit key enzymes associated with metabolism of food constituents, e.g., proteinases and carbohydrases (α-amylase). The role of these inhibitors is the subject of much speculation. However, much interest has focused on the potential of plant derived protease inhibitors to confer ‘anti-nutritional’ properties to plant protein extract/isolates.
In vivo bio-accessibility and bio-availability of proteins / peptides will be accessed using the Digestible Indispensable Amino Acid Score (DIAAS) to address the individual dietary amino acid digestibility. In addition, the team at Queens University Belfast will evaluate human metabolic responses to the consumption of novel plant/marine protein sources selected in Task 2 and processed in Task 3.
