Our lab focuses on the food carbohydrate chemistry. The overall research goal is to maximize the use of renewable and readily accessible carbohydrate feedstock in the food industry. Research topics include the interaction of carbohydrates with food components on quality, sensory, digestion, and health properties of foods; carbohydrate-derived materials with novel physicochemical and nutritional properties; and chemical modifications of carbohydrates for food applications. Additional research interests are high-intensity ultrasound, deep eutectic solvents, and food nanotechnology.
Research Project Example
Ice recrystallization is a ubiquitous thermodynamically driven process that adversely affects cryopreserved cells and foods. Inhibiting ice recrystallization is crucial to the development of high-quality frozen foods, such as ice cream. Secret ingredients have been used to inhibit ice recrystallization by ice cream manufacturers. However, it is not clear how these ingredients interact with ice and inhibit ice recrystallization exactly. Recently, we have discovered nanocelluloses as novel ice recrystallization inhibitors. We will study the structure-activity relationship of these materials and understand how they interact with ice. The completion of this project will advance our understanding of how food ingredients influence ice recrystallization, thereby benefiting the frozen food industry.
