Research vision and interest

Dr. Sun鈥檚 research aims to apply innovative processing technologies for improvement of health benefits, nutritional quality, and functionality of food proteins, to add value to by-products from food, agriculture, and aquaculture, to develop new protein-based food products with healthy, sustainable, and sensory attributes, and to understand their underlying fundamental mechanisms.

Primary research interests include:

• Effects of food processing on the physicochemical, functional, nutritional, biological, structural, and sensory properties of food proteins
• Identification of novel food-derived bioactive peptides and elucidation of the underlying mechanism
• Modification of plant-based proteins for enhanced functionality by physical, chemical, and enzymatic approaches
• Development of novel plant-based food products as alternative protein sources
• Designing novel food macromolecule-based nanocarriers for encapsulation, protection, sustained release, and site-specific delivery of bioactive compounds
