Competitive Agricultural Economy: Integrating Food Processing and Safety

Dr. Rasco has established a leading program applying fundamental principles to the production of safe, high quality food products with the overarching objective of ensuring that agricultural economies can remain sustainable and viable. She has also integrated technology and law to address a number of important food safety and security issues.
Her research focuses primarily on process development and process control for high-value aquatic foods and other foods important to the Pacific Northwest. Recent efforts in product development have improved the economic viability of regional aquatic food processing and aquaculture operations. Current studies involve the development of improved pasteurization methods and active packaging to extend shelf life of thermally labile high-value foods. Other recent studies include evaluation of how the physical and chemical properties of food are altered by dielectric heating.
Dr. Rasco has designed, constructed, and tested enzyme-based biosensors for dielectric heating applications and electrochemical, ultrasonic, and infrared sensors for food process validation. On a more fundamental level, she develops biochemical and spectrophotometric methods to rapidly identify and quantify chemical constituents in complex food matrices, primarily for fish and aquatic food products.
Dr. Rasco and her colleagues have also developed non-invasive spectral methods to detect tissue damage and to determine the reproductive status of salmon and sturgeon. In the food safety arena, they develop pattern recognition techniques to classify foodborne pathogens and spoilage microbes by Fourier Transform Infrared Spectroscopy (FT-IR). They were the first to use FT-IR methods to detect microbial cell injury resulting from environmental stress, and the first to use FT-IR to compare phylogenetic and spectral features of spore forming thermophiles that cause food spoilage.
