Course abstract

The organic matters nature and main classes of their modifications are characterized by course. The structure and properties of proteins, carbohydrates and lipids are examined in the chapter „Organic Chemistry”. Fundamentals of Physical and Colloidal Chemistry inspect general characteristic of solutions, chemical kinetic, surface effects, dispersed systems, colloidal solutions and solutions of biomacromolecules.

Learning outcomes and their assessment

Extensive knowledge about properties and structure of lipids, carbohydrates and proteins in food products; about generality, occurrences and processes of physical and colloidal chemistry related to food technology - Tests;
skills to use the obtained theoretical knowledge about lipids, carbohydrates, proteins in other study courses; to use theoretical and practical knowledge to carry out professional and research activities - laboratory works;
competence - the ability to independently access, select and analyze information about lipids, carbohydrate and protein in different food products; to use information, to make and explain decisions and solve scientific and professional issues - colloquium.

Requirements for awarding credit points

Exam. in the first semester in full time and in the 2nd semester in part-time study program, if 7 tests and all laboratory works have been completed.

Description of the organization and tasks of students’ independent work

Preparation of laboratory reports - compilation and systematization of chemical reactions, observation, conclusions and experimental progress.

Criteria for Evaluating Learning Outcomes

It is necessary to write successfully all tests, i.e. no lower mark than 4 points. All laboratory work protocols must be checked and completed. If the accumulated mark of successful written tests is not less than 7 (good) and all the laboratory works are completed, then exam does not have to be written.
