Course Description
This course provides information on foodborne microorganisms and their role and
significance in quality and safety of foods. Factors affecting life and death of
microorganisms in foods. Microbiology of selected food commodities with emphasis
on safety and quality. Role of microorganisms in food processing. Practical part
provides basic knowledge and skills needed in food microbiology laboratory.
Learning Objectives
1- Outline significance of microorganisms in food.
2- Understanding microbial taxonomy and classification of foodborne
microorganisms.
3- Recognizing that microorganisms are constantly affected by the surrounding
factors.
4- Understanding that microorganism in foods vary from spoilage to pathogens to
processing.
5- Relating presence of specific microorganism in specific foods.
6- Introduction to food biotechnology and microbial food industry.
