|I am professor in Predictive Food Microbiology study microbiological quality and safety of fresh and lightly preserved food. The overall aims of this research are to obtain insight into the quantitative microbiological ecology of fresh and lightly preserved food and to use this information for development of new methods and strategies to determine, predict and improve the safety and shelf-life of products. The Food Spoilage & Safety Predictor (FSSP) software has been developed to facilitate dissemination and application of results from the research group.
Research: I study how processing, product characteristics, and distribution systems influence microbial responses including growth, activity and survival in food. These responses have been studied in the continuum from the raw food material to the arrival of the final product to the consumer. Predictive microbiological models and software to predict shelf-life and safety have been developed by combining the analysis of product characteristics using chemical, physical and microbiological measurements with process modelling and kinetics for growth and survival of microorganisms. I have a strong experience in working with aquatic food and increasingly study other foods including dairy, meat and vegetable products. My laboratory is internationally oriented and regularly host research visits by international scientists.
Software development: The Food Spoilage and Safety Predictor (FSSP) software has been developed and is freely available at http://fssp.food.dtu.dk/. FSSP and the earlier version named Seafood Spoilage and Safety Predictor (SSSP) is used by more than 8000 individuals orinstitutions from more then 110 different countries.
Teaching activities: My teaching includes supervision of project students at the B.Sc., M.Sc. and Ph.D.-levels and lecturing at DTU and at the University of Copenhagen. I am responsible for the following courses at DTU:
- Safety and Health Effects of Aquatic Food (23154 - see link above)
- Predictive Food Microbiology (23551 - see link above)
Advice to industry and authorities: I regularly provide advice to industry and authorities when they have questions regarding microbial spoilage, shelf-life and safety of seafood. Workshops on using the FSSP (and previously SSSP) software is organized regularly.
Reviewer and editor activities: Member of the Editorial board of International Journal of Food Microbiology (1995- ) and of Journal of Food Protection (2008-2010). Ad hoc reviewer for more than 20 different international scientific journals and in total reviewer of more than 500 manuscripts. Guest Editor for two special issues of International Journal of Food Microbiology in 2008 and 2010 and for one special issue of Food Microbiology in 2015.
