Biography
Dr. Liu completed Bachelor, Master, and Docter Degrees from Tianjin University at 2008, 2010 and 2013 and joined Tianjin University of Science and Technology since then. She is engaged in more than 10 projects at the level of nation, province and ministry. She published over 40 scientific papers, and served as a reviewer for more than 4 international journals.
Research Interests
Regulation of the rheological properties of wheat gluten network is a common economic and technical problem in food processing, and the rheological properties of wheat gluten were considered a consequence of the integrated affection of protein molecular structures and their interactions. To understand the interaction mechanism of wheat gluten proteins and the changes in protein rheological properties, we plan to focus on the micro- and meso-scale studies of interactions of wheat gluten proteins and their structure-activity relationship with rheological properties. The micro-structures of wheat gluten proteins, meso-aggregation states and molecular interactions were analyzed quantitatively by CD, DLS, SEC-MALLS, MS and NMR. Dr. Rui Liu plan to establish the structural dynamics and formation dynamics of wheat gluten in food processing, in combination with the investigation on protein interaction mechanism, to reveal the formation behavior and molecular mechanism of wheat gluten network. Furthermore, we plan to explore the important role of molecular interaction as a link between micro-structural changes and meso-properties, reveal the dynamics and thermodynamic properties of wheat gluten proteins, and further establish the micro- and meso-structure-activity relationship with rheological properties. The methodologies in this project and its prospective results could lay theoretical foundation for the in-depth development of wheat gluten processing technology. Thus, Dr. Liu extend her research to the structural analysis of other food multi-components and their interaction mechanisms in foods. A series of significant papers were published on these areas.
