Area(s) of Expertise
The mission of the Food Science Research Unit, USDA-ARS, SAA, located in Raleigh, NC, is to carry out basic and applied research related to processing, safety and quality of fermented and acidified vegetables including cucumbers, peppers, cabbage and sweetpotatoes. Areas of investigation include chemical and sensory properties of fermented and acidified vegetables, fermentation biochemistry, and metabolite profiling by GCxGC-ToFMS.
The current objectives of my program are to:
- develop reduced salt fermentation procedures for cucumbers that will assure microbiological stability and maintain or improve product quality;
- preserve non-fermented cucumbers and peppers in acidified low salt solutions to be used as process-ready ingredients for food products;
- preserve the textural, sensory, and visual qualities of fermented and acidified vegetables and sweetpotatoes;
- develop improved analytical methods for chemical characterization of fermented and acidified vegetables and sweetpotatoes; and
- develop fundamental knowledge of the biochemistry of bacterial responses to acid environments in order to develop practical approaches to assure microbial safety of acidified vegetable products.
The long-term goal of my program is to work at the intersection of applied and basic research to improve product quality, reduce processing wastes, and advance the science of fruit and vegetable preservation.
