Food Microbiology (BIO600)

Food as ecological niches. Foodborne bacteria. Infections and intoxications connected to intake of food. Chemical and physical factors affecting microorganisms in foods. Qualitative and quantitative methods for detection of microorganisms in food. Food fermentations.

The student will have knowledge on the presence of pathogenic and poilage microorganisms associated with different foods. The student will have specific knowledge on actual microorganisms in different raw materials and the health risk of food borne infections and intoxications. The student will understand how microorganisms grow, and can be used in a positive manner and also controlled in foods. The student will understand how to use qualitative and quantitative analysis of microorganisms based on theory as well as practical work. The student will have knowledge on physical, chemical and microbiological methods to control both quality and heath risks in foods.
