Biography:After completing his PhD in plant biochemistry at La Trobe University in Melbourne in 1973, Owen Young undertook postdoctoral study in California and New Zealand before working for 25 years as a researcher in the meat industry. He has now been at AUT for 10 years and has expanded his food interests beyond meat, although he still has connections and research projects in that industry. The research focus to date at AUT has been in industry trouble solving for smaller New Zealand food companies, and on food product development.
Teaching Areas:Food Chemistry, Research Project Design
Research Summary:While much of his research was applied to solving meat industry problems, he also was able to contribute to research on why meats have different eating qualities. He helped develop and understanding of which meat proteins are responsible for tenderising meat on storage, and, in chemical terms, why New Zealand lamb has a unique flavour. He also invented a method, which is in commercial use in New Zealand to predict ultimate meat quality within 20 minutes of slaughter; at the same he championed the development of value-added meat products particularly of sheepmeat.
At AUT the involvement with the meat industry has continued with supervision of postgraduate research in topics as different as industrial cooking of meats, the role of heat shock proteins in meat tenderness, electrical stimulation of carcasses, colorimetric and near infrared methods to predict final meat pH, and evaluation of a prerigor packaging on tenderness. Beyond the meat industry, the focus has been on industry problem solving for smaller New Zealand food companies, and on food product development. The problem solving has been on topics as diverse as food allergen control in chicken processing, spirit still evaluation, development of gluten free products, elimination of bitterness in oat products, use of cyclodextrins to reduce goaty flavour in goat milk yoghurt, and applications of kiwifruit enzymes in human enteric health. Most of these projects have been funded by government and companies supporting the students involved. Another notable supervision has been on the culturing of high-fat native New Zealand eels for the Asian and European markets. This last supervision is one of several where food product provenance has been a focus, notably the use of New Zealand native woods instead of oak to flavour wine and spirits, the development of a range of lactic fermented seafood products, and the recreation of a novel spirit from an iconic New Zealand plant.
Professor Young is the author or co-author of 80 refereed research papers, 40 confidential meat industry reports, one book, and nine book chapters. He was the co-editor of the international textbook, Meat Science and Applications (Marcel Dekker, New York). About half his supervisions at AUT cannot be published, or are unsuitable for publication due to their nature, but nonetheless have contributed to meat industry developments.
Current Research Projects:The food industry research focus described above continues, along with food product development with a particular focus on provenance. Provenance is important for food marketing, knowing that unique products from a particular geographic region command a price premium over generic equivalents. This approach is being applied to a New Zealand-unique alcoholic spirit and to innovative fermented seafood products by a variety of undergraduate and postgraduate students. Three other current projects are development of novel polymers from amaranth starch (a co-supervision with Plant and Food Research), comparison of two electrical stimulation systems for bovine carcasses (industry funded), and evaluation of a miniature dried food extruder (industry inspired).
Topics suitable for postgraduate study include:
- Development of novel food and drink products from indigenous New Zealand species, with a particular emphasis on lactic and alcoholic fermentations.
- Food industry problem solving. The occurrence of these projects cannot be predicted but typically one or two emerge each year. They are usually funded so the student is paid a stipend.
