Objectives

To provide the students with the basic knowledge and training to achieve a clear thinking about the methjods of seafood handling and processing, as well as a modern perspective of the food quality and corresponding technical and scientific skills, in order to prepare the students for the professional work they will have to develop. The capacity to criticize, to find and choose the right information and the contact with the realistic professional environment are favoured, by visiting industry facilities.
The students should be able to describe, in a critical way, the characteristics and composition of seafood, food degradation, processing and preservation methods, and also quality and freshness evaluation methods.
