Objective (expected results of study and acquired competences)

After successful participation of this course, the students are familiar with basic know how of food processing. In particular they have learned about processes and methods for cooking and preparation, as well as prolonging the shelf life of food. With this fundamental knowledge the students can subsequently understand the topics lectured in the special technological courses and can see the connections between single food processing methods.
