Research Interests

Professor Ng’s research foci have been mainly in the areas of physicochemical and genetic properties of wheats (mainly of wheat flour proteins) in relation to end-use qualities, cereal (wheat, barley, rice, etc.) chemistry and technology, extrusion technology in cereal processing, and utilization of non-cereals (e.g., soybeans) for food and non-food products.  In recent years, his research activities have extended into areas such as cereal fiber and gut health, cereal food allergies, and modifying certain components (e.g., resistant starch, fiber, phenolics) in grain with potential for functional food ingredients. In light of his contributions to cereal science, Prof. Ng was named Fellow of the American Association of Cereal Chemists International in 2010 and Fellow of the International Association for Cereal Science and Technology Academy in 2012.  He has been invited to many research centers (public and private) in Africa, Asia, Europe, Oceania, North America and South America to present his research findings.  His cereal/food science expertise has been sought out by universities, governments, and the food industry (e.g., in Canada, the European Union, Indonesia, Japan, Korea, and the USA) for consultative and expert panel purposes. He has a personal interest in assisting countries with a need to improve food quality (e.g., nutrition, shelf-life, safety) and/or add value to their local food production (e.g., novel products with nutraceutical and health benefits) via various food processing technologies.

Outreach Focus

Prof. Ng has a passion for capacity building in developing countries. He oversaw a USAID-funded project of the Initiative for Long-Term Training and Capacity Building Program, in which a group of Malawi students studied to obtain their M.S. degrees in Food Science from MSU; he was the Deputy Program Director for the Borlaug Higher Education Agricultural Research and Development (BHEARD) Program, also funded through USAID; and he was the MSU Co-PI on the Food and Nutrition Technical Assistance (FANTA III) program.
