Research Interests

My research interests are in the areas of dairy science & technology, dairy product development, the component changing mechanism during processing, especially cheese processing and application. Mozzarella is one of the most popular cheeses. Rheological properties are the most important processing quality for Mozzarella. Currently there is no systematic study of changes in the rheological properties of Mozzarella cheese under the change mechanism of different rheological state and the intramolecular structure. This project use the glass transition theory to research the rheological properties of Mozzarella. We use DSC detect the thermal characteristics combined with thermodynamic models and equations to get the state diagram of Mozzarella. The Mozzarella cheese was divided into three states: glassy, rubbery and viscous flow state. We detected the rheological properties in different state, use fluorescence spectroscopy to study the hydrophobic interaction changes, use Fourier Transform Infrared Spectroscopy to study the secondary structure changes of cheese protein, analysis the structure and intermolecular forces changes.
