Areas of interest

My main area of interest is in functional food ingredients. Specifically:

  • Structure-function relationships in fermented carbohydrates in the diet.
  • Development of novel prebiotic carbohydrates with a range of functional enhancements over the current market leaders. Several disease states and vulnerable population groups are being targeted by this research.
  • Design of prebiotics targeted at specific microbial groups in the gut microbiome. This approach is allowing the development of rationally designed synbiotics.
  • Utilisation of food waste as sources of functional food ingredients. Current work is focussing on plant biomass as a source of candidate prebiotics.
  • Development of enzymatic synthesis approaches for oligosaccharides based on the use of microbial and plant glycosidases as synthetic catalysts. This is allows us to create a range of novel, potentially bioactive, structures.
  • Development of controlled enzymatic hydrolysis technology for manufacture of oligosaccharides. This facilitates the production of controlled molecular
  • weight ranges in functional carbohydrates.
  • Production of microbial polysaccharides, polysaccharide degrading enzymes and bacteriophage by fermentation.
  • Manufacture and evaluation of oligosaccharides that act as receptors for pathogenic micro-organisms.
