Research Areas

Our group focuses on effective utilization of  bioresources and production of bioactive substances, such as rare sugar, polyol, polysaccharide, bioactive peptide, and sugar-protein complex. We are using enzyme and biocatalysis engineering technology to develop these functional sugars and bioactive peptides as food additives. We have also contributed structural and functional support to a project of glycated proteins aimed at characterizing important sugar-protein complexes. We are aiming to increase our screening capacity to rare sugar transforming enzyme by traditional method combined with genetic mining. The mission of the lab is to establish the  biocatalysis technical platform for transforming the bioresources into the novel  active substance.

The research is developing the novel functional factors and food for modulating the effect of diet on health and disease. In nearly five years, the more than 60 research papers are published on J. Agric. Food Chem., Protein Cell, Biotech. Bioeng., Appl. Microbiol. Biotech., Appl. Environ. Microbiol. et al. journals, and 23 patents are applied. In the other hand, I have a great deal of management experience in scientific research, and have led natural science fund in the biotechnology and food processing, the some outcome have been used to industrialize. I am also an expert with special government allowance of State Council in 2015, and I am a participant of planning compilation in food processing field with Ministry of Science and Technology, China.

Research Interests

My research focuses on effective utilization of bioresources and production of bioactive substances, such as low calorie rare sugar, dulcoside, polysaccharide, bioactive peptide and so on. I am using enzyme and biocatalysis engineering technology to develop these functional compounds as food additives. The mission of my research group is to establish a biocatalysis technical platform for transforming the bioresources into the novel natural bioactive substance. Furthermore, the developing functional factors and food influences modulating the effect of diet on health and disease. The long-term goal is to improve the management of obesity, diabetic and cardiovascular diseases by diet throughout life.

Collaboration

We hope that our technologic achievements in food processing could be transformed by cooperating with enterprises and promoted their industrialization. At the same time, we hope to collaborate and exchange in scientific and technology among OWSD members, and to aid developing countries.
