Texture Modified Foods
Texture modified foods for people with chewing and swallowing difficulties (dysphagia) can occur throughout life, but are particularly common in the elderly. I have an interest in creating products to meet this important need, and in developing measurement techniques for the study of texture modified foods. The studies of measurement techniques includes objective methods (e.g. automation of the International Dysphagia Diet Standardisation Initiative [IDDSI] for press test; bolus texture measurement), and sensory (e.g. chewing parameter to form a swallowable bolus from meat; particle size distribution produced by chewing).
Food Characterisation for Identification and Authenticity
Application of a combination of spectroscopy techniques, including Raman spectroscopy and IR spectroscopy, and chemometrics, to the characterisation and differentiation of foods types. This includes different species (fin and shell fish), muscles (within cattle and chickens), carcass location (within fin and shell fish), chemical indicators of quality (carotenoid levels in salmon and trout, level of histamine). This approach has also been applied to characterisation of cheeses, including manufacturer and maturity level of cheddar cheeses, and differentiating cheeses made with very different manufacturing processes (e.g. cheddar, feta, camembert, blue vein, parmesan). I am currently looking to extend this work to include PFAS and microplastic levels in fish.
Commodities of Interest
Australia is a producer of a wide range of commodities, and my interests are correspondingly broad. I have a major interest in meat and meat products, having led and worked in meat research programs in Australia, New Zealand and the USA.
