Sun Dawen (simplified Chinese: 孙大文; traditional Chinese: 孫大文; pinyin: Sūn Dàwén), born in Chaozhou (潮州), Guangdong (广东), China (中国), known as "Da-Wen Sun".

Biography

Professor Da-Wen Sun was born in Southern China. He received a first class BSc Honours and MSc in Mechanical Engineering, and a PhD in Chemical Engineering in China. He was appointed College Lecturer at National University of Ireland, Dublin (University College Dublin) in 1995, and was then Senior Lecturer, Associate Professor and full Professor. Dr Sun is now Professor and Director of the Food Refrigeration and Computerised Food Technology Research Group in University College Dublin. He is a Fellow of the Institution of Agricultural Engineers. He is also a member of CIGR Executive Board and Honorary Vice-President of CIGR, Editor-in-Chief of Food and Bioprocess Technology – an International Journal (Springer), Series Editor of “Contemporary Food Engineering” book series (CRC Press / Taylor & Francis), former Editor of Journal of Food Engineering (Elsevier), and editorial board member for Journal of Food Engineering (Elsevier), Journal of Food Process Engineering (Blackwell), Sensing and Instrumentation for Food Quality and Safety (Springer) and Czech Journal of Food Sciences. He is also a Chartered Engineer registered in the UK Engineering Council.

Academic career

Da-Wen Sun is an internationally recognized figure for his leadership in food engineering research and education. His main research activities include cooling, drying and refrigeration processes and systems, quality and safety of food products, bioprocess simulation and optimisation, and computer vision technology. Especially, his innovative studies on vacuum cooling of cooked meats, pizza quality inspection by computer vision, and edible films for shelf-life extension of fruit and vegetables have been widely reported in national and international media. Results of his work have been published in over 180 peer reviewed journal papers and more than 200 conference papers.

As a leading educator in food engineering, Professor Sun has significantly contributed to the field of food engineering. As a recognised authority in food engineering, he has been conferred adjunct/ visiting/ consulting professorships from ten top universities in China including Zhejiang University, Shanghai Jiaotong University, Harbin Institute of Technology, China Agricultural University, South China University of Technology, Southern Yangtze University, and so on. In recognition of his significant contribution to food engineering worldwide and for his outstanding leadership in the field, the International Commission of Agricultural Engineering (CIGR) awarded him the CIGR Merit Award in 2000 and again in 2006, the Institution of Mechanical Engineers (IMechE) based in the UK named him “Food Engineer of the Year 2004”, in 2008 he was awarded CIGR Recognition Award in honour of his distinguished achievements as the top one percent of Agricultural Engineering scientists in the world.

Honours and Awards

He has also received numerous awards for teaching and research excellence, including the President’s Research Fellowship, and twice receiving the President’s Research Award of University College Dublin.

Research contribution

The research conducted by Professor Da-Wen Sun and his research team is an important component in Food Process Engineering. The research has attracted the attention of quality publications including the prestigious New Scientist. Their 2001 issue (vol 172, issue 2321, 15 Dec, p 24) focused on the potential of edible food coatings to extend the shelf life of fruit and vegetables. A soya-based coating had already been used to preserve kiwi fruit for 37 days without any sign of rotting. The fruit normally lasts just a fortnight. The coating does much the same job as packaging, only better, according to Dr Sun’s collaborator Shiying Xu, a food scientist at the Wuxi University of Light Industry in China. "Our film can inhibit gas exchange, control respiration rate, decrease nutrient loss, reduce evaporation and prevent the micro-organism growth that causes rotting," she explains. To protect a piece of fruit, you dip it in a solution of the coating, which dries to form a thin, transparent film. Although people usually peel kiwi fruit, the coating has to be edible because chemicals from it could migrate through the fruit's skin. The coating is a mixture of soya protein, a fatty acid called stearic acid, and pullulan—a sugary carbohydrate which is produced by a fungus and which forms sticky films. Xu says the coating should also work for apples, tomatoes and peppers, but the relative amounts of each constituent would have to be changed for each type of fruit, and that could make it expensive.

Dr Sun says it's hard to tell just how long the coating would preserve other types of fruit, since they all have such varied shelf-lives. Citrus fruits, for example, can last months before rotting—and that's without the coating. Like the supercool substitute for menthol, the fruit-saving film will need to go through rigorous tests before it can be approved for commercial use, says Britain's Food Standards Agency.

In 2002 the New Scientist focused on spotting a perfect pizza (vol 176, issue 2373, 14 Dec, p 9). Lamenting the "inaccuracy and subjectivity" of quality controllers in pizza factories, Da-Wen Sun and Tadhg Brosnan suggested that the task demanded a more rigorous mathematical approach best done by a machine. They have turned to fuzzy logic and designed algorithms that can analyze snapshots of pizzas from digital cameras and automatically pick out rejects - the ones that just don't look tasty enough. In two papers in the Journal of Food Engineering (vol 57, p 81 and p 91), they explain how their invention can diagnose a variety of worrisome pizza ailments, including patchy sauce, sparse coverings of toppings such as mushrooms or ham, and that bane of so many would-be perfect pizzas, a base with "poor alignment".
