Course objectives

The main objectives of this course are to enable students to understand and implement good practices in seafood handling processes by understanding the principle” from catch to fork”; selection of appropriate methods of conservation and implementation of good manufacturing practice during the different seafood processing technologies.

Course enrolment requirements and entry competences required for the course

Competence in applying knowledge of inorganic and organic chemistry and microbiology and biochemistry.

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After passing the exam, the students will be able to:
- identify all phases of post mortal changes in fish meat;
- identify and analyze metabolites of specific spoilage microorganisms
- implement different methods of preservation of fishery products in accordance with good manufacturing practice;
- define and implement the necessary methods of assessing the quality of raw material, technological processes and final products of fish processing industry.
- calculate the norms/yields necessary for the organization of production in the fish processing industry
- identify and eliminate problems in the technological processes
- identify critical control points in the production processes, carry out hazard analysis for different technologies and preventive and corrective measures to ensure food safety
- Independently implement HACCP plan.
