The course covers complex facts about particular chemical components and their functions and changes in food and natural products. The interpretations of their physicochemical, biochemical and other significant properties that students will use in solving selected case studies are also important part of the subject. Significant interactions and reactions that take place in biological materials, including food during storage and technological or culinary processing, and lead to changes in nutritional, toxicological, technological or sensory quality at the same time are descripted in particular examples and analysed in detail. The course includes both main nutrients and essential nutritional factors, antinutrients, toxic and other biologically active components of food and natural products.

Last update: Cejpek Karel doc. Dr. Ing. (29.06.2018)

Completing the course, students will understand the chemical background of important complex processes in food and natural products. The ability to evaluate reactivity or stability and to identify both desirable and undesirable chemical and biochemical key reactions of food and natural product components will be a main output. The enhancement of presentation skills when the student prepares a short message presented to others within the subject will be also beneficial.

The first part of the course deals with general topics including the most common reaction mechanisms, kinetic description and thermodynamic characteristics of complex systems - food and natural products.

The second, the largest part of the course covers the most important reactions and interactions of the main nutrients - proteins, lipids and carbohydrates, essential nutritional factors - vitamins and minerals, sensory active substances - especially pigments and flavours, biologically active substances including antinutritional and toxic components, processing contaminants etc.

The third part of the course completes the above with the reaction mechanisms and kinetics of enzyme reactions and an overview of the main pathways that lead to the biosynthesis of principal food components. The course also includes presentations and discussions of complex food reactions and the relative importance of individual reactions in particular commodities under specific conditions.
