I like to apply a multi-disciplinary approach involving chemistry, microbiology, product development, flavour and sensory science to gain an understanding of how factors such as raw material characteristics, product formulation, handling methods, or processing and storage regimes impact on a food's safety, stability (shelf-life) and sensory properties. I have worked with a wide range of companies on projects in the dairy, vegetable, seafood, meat, brewing and wine industries.
- Enhancing the quality, flavour attributes and shelf-life of foods.
- The application of volatile analysis to study of food quality and/or microbial growth.
- The development and assessment of microbial control regimes (sources of pathogens, thermal processing, washing, marinades, steam treatments)
- Development and validation of cleaning and sanitising regimes.
- Bacteria/metal interactions (metal cation binding to bacteria or bacteria attaching to metals)
- Understanding the factors affecting the attachment of bacteria to surfaces.
- The development of antifouling surfaces to limit bacterial attachment and marine fouling.
