Course abstract

The objective of the course is to provide thorough knowledge on chemical structure and chemical transformations of the low molecular weight compounds forming food ingredients (proteins, lipids, carbohydrates, vitamins, minerals, etc.).
The tasks of the course are:
1) deepening of the knowledge on the structure and possible transformations of chemical compounds (organic and inorganic) as a result of the action of the environment and other compounds;
2) deepeding of the knowledge on detection methods of the low molecular weight (organic and inorganic) compounds.

Learning outcomes and their assessment

Knowledge:
1) about construction and periodical system of chemical elements, chemical composition and possible chemical transformations of the compounds that make up the food composition;
Practical skills:
2) individually or cooperating in small groups explain, analyse and assess construction of the chemical compounds and their elements and forecast their possible chemical transformations;
3) encourage further learning and acquirement of knowledge by using different sources of information;
Competencies:
4) in the course “Food chemistry” will be able to understand and forecast the chemical changes of the composition of food ingredients in processes of food storage and processing and biochemical transformations of the food ingredients in living organisms, assessed in the course “Human biochemistry and molecular biology”.

Requirements for awarding credit points

Participation in seminars and intermediate tests is mandatory.
The final rating of the study course will be resulted from the:
1) results of intermediate written test 60% and discussion of their results, as well as active participation in the seminars;
2) results of the written examination – test 40%.

Description of the organization and tasks of students’ independent work

Independent work of students is organised on individual basis and/or in working groups by assigning the following tasks: to prepare independently for seminars and intermediate examinations, final examination; to study literature on topics related to respective course.

Criteria for Evaluating Learning Outcomes

The final rating of the study course will be resulted from the:
1) results of seminars and intermediate written tests (60%) and discussion of their results;
2) results of the written examination – test 40%.
