Research Interests
My research program covers basic and applied
studies on chemistry, processing, and functional properties
of carbohydrate-based food materials. Special attention
is focused on sweetpotatoes with an ultimate goal of increasing
utilization of this highly-nutritious vegetable in processed
food products. Current areas of research include: 1) new
processing strategies to convert sweetpotatoes into functional
ingredients that are readily available for the food processing
industry; 2) functionality of these ingredients in various
food systems; 3) nutrients and beneficial phytochemicals
in sweetpotato products: selection of genotypes with increased
concentrations of target components and optimization of
processing conditions to minimize losses; 4) effects of
processing and storage on chemical constituents related
to textural properties, flavors and sensory characteristics
of sweetpotato products.
The program also aims to collaborate
closely with the sweetpotato industry and food companies
to identify relevant research areas and transfer the developed
technologies from our program for pilot-testing and commercial
development.
