Professor Benjamin Simpson is a graduate in Biochemistry from Memorial University of Newfoundland, where he also carried out postdoctoral work till December 1985. He joined the Food Science Department at 海外直播b站 in June 1987 after spending a period of time at the Institute of Food & Agricultural Sciences (IFAS), University of Florida at Gainesville in the USA, as a Research Associate from January 1986 to April, 1987. His research program involves the post-mortem biochemistry of marine organisms, in relation to enzymes. Specifically on digestive enzymes from marine animals, their characterization to discover their unique properties that may make them better suited for particular applications compared with their traditional counterparts; role of enzymes in color and texture deterioration in fish and shellfish and development of strategies to control the deleterious effects of enzymes in foods during processing and storage; and the use of enzymes in transforming discards from food harvesting / processing into value added products of commercial relevance. Examples of the value-added products prepared by the enzyme assisted procedures include natural food pigments, proteins, bioactive peptides, flavor compounds and chitin, etc., for use as food processing aids. Dr. Simpson is responsible for teaching Food Commodities, Food Chemistry 2 and Enzymology.
- Enzymes from marine organisms (digestive enzymes, transglutaminase, polyphenoloxidase)
- Post-mortem biochemistry of fish/shellfish
- Chitin and chitosan from crustacean waste
- Biodegradable plastic films from chitosan, gelatin and zein
- Carotenoid pigments from crustacean waste
- Biodiesel from fish skins
Research activities have 2 main foci:
- on the post-mortem biochemistry of marine organisms - more specifically on the role of naturally present enzymes in seafood in postharvest seafood quality alterations;
- using 鈥済reen technologies鈥� to enhance the value of seafood harvesting/processing waste material.
