Research interest

Dr. Sun Hong-Nan, appointed as the Deputy Secretary-General of the National Potato Staple Industrialization Technology Innovation Alliance, the Director of Beijing Food Society, and the Chief Scientist of the National Key R & D Program of the Ministry of Science and Technology of the P.R. China, presides over or participates in more than 35 projects in the National Key R & D Program of the Ministry of Science and Technology, the Horizon 2020 project of European Commission, the NSFC project, the Science and Technology Innovation Project of Chinese Academy of Agricultural Sciences, the Earmarked Fund of Public Welfare Industry (Agriculture) Research Project, the Modern Sweet Potato Food Processing Technology Research System of Ministry of Agriculture of P.R. China, etc. She is the author of 35 CN patents, 3 national and agricultural industry standards, 61 peer-reviewed journal publications, and 9 books or book chapters. Her research achievements have passed 3 appraisal and evaluation of achievements, and won 9 influential awards, such as the 17th Chinese Patent Excellence Award, CAAS Scientific Achievement Awards, Chinese Agricultural Science and Technology Award, Chinese Cereals and Oils Association (CCOA) Science and Technology Achievement Award, etc.

  The main research interest is as follows:

1. Preservation technologies of post-harvest potato and sweet potato

In view of the major industrial problems such as large losses (about 20% to 30%) and serious quality deterioration of the post-harvest potato and sweet potato, the main research content includes (1) the occurrence and regulation mechanism of nutritional quality deterioration and flavor loss of post-harvest potato and sweet potato; (2) the preservation technologies of post-harvest potato and sweet potato related to callus, precooling, commercial treatment, storage, transportation, etc.; and (3) new compound fresh-preserving agent / compound coating antistaling agent.

2. Processing technologies of nutritious potato and sweet potato products

In view of the major industrial problems such as the evaluation of potato and sweet potato processing characteristics is not systematic and complete, and the level of processing technology and equipment for nutritious and healthy products needs to be improved, the main research content includes (1) the evaluation of potato and sweet potato processing suitability; (2) the quality formation and control mechanism of potato and sweet potato products; and (3) the key technologies of potato and sweet potato processing.

3. Comprehensive utilization of by-products from potato and sweet potato processing

In view of the huge output of potato and sweet potato processing by-products (waste water, residues, and sweet potato leaves), resource waste, environmental pollution and other major industrial problems, based on the upgrading of China's market consumption and residents' demand for nutritious and healthy food consumption, the main research content includes (1) the efficient preparation technologies of protein, dietary fiber, pectin, polyphenols and other nutritional and functional components from potato and sweet potato processing by-products; (2) the biological activities of the above mentioned nutritional and functional components, such as antioxidant, hypoglycemic and antihypertensive activities, and their mechanisms; and (3) the research and development of nutritional and functional food products with high quality.
