Annotation -
The scope of this course is principal chemical reactions of important food components that occur during storage, culinary and technological processing of foods, which lead to changes in nutritional, sensory and health quality.
Last update: Cejpek Karel (26.01.2018)
Aim of the course -

Students will be able to

  • describe the reaction mechanisms for the principal reactions of nutrients and other food components
  • evaluate the information about the chemical and physical parameters that determine in which direction and how far the food components react, and how quickly the reactions are carried out.
  • design effective control over important reactions in food practice.

Course completion requirements -

Successfully passed exam. During the term, students complete usually three partial tests, which are required to be passed successfully and their results are taken into account in the examination. Individual projects are not compulsory, but students can receive a bonus rating. The exam is in the form of a final test, which can be completed with the oral part of exam by a discussion on particular questions.
