Course abstract

Within the study course “Chemistry of Natural Substances”, students acquire knowledge about compounds that form food products of animal and plant origin. Proteins, carbohydrates and lipids, that make up the energy nutrition of food, will describe in this course. Significant knowledge about biologically valuable compounds in food - vitamins, minerals, fiber, essential amino acids and essential fatty acids will be obtained. More attention will be paid on compounds that form the sensory properties of food products - color, smell and taste. Polymers of isoprenoids as well as groups of plant polyphenols will be considered. Students use the acquired knowledge, skills and competencies when writing a master's thesis.

Learning outcomes and their assessment

Knowledge
Knows the compounds that make up the energy value of foods - test
Skills
Ability to independently search, select and arrange information for a report on the composition of two different foods – presentations, report.
Competencies
Students are able to apply the acquired knowledge and research skills to evaluate, analyze and interpret the collected and arranged information on the comparison of two different food-forming compounds – presentations, report.

Requirements for awarding credit points

The study course results are evaluated on a 10-point scale.
The course ends with a written exam. The course is considered successful if the exam grade is not lower than “4” (almost satisfactory).
The student is admitted to the written exam if the test, the presentation of the research paper and the report on the comparison of the chemical composition of two similar or different food raw materials are included.

Description of the organization and tasks of students’ independent work

The students independently prepare answers to the test questions on food lipids, carbohydrates and proteins.
The student prepares a presentation on the comparison of the nutritional value of two or more animal raw materials.
The student prepares a presentation and a report on the comparison of the nutritional and sensory properties of two or more plant raw materials. The volume of the report is not less than 15 pages.

Criteria for Evaluating Learning Outcomes

The study course ends with an exam.
The assessment of the study course exam consists of the assessment of the examination (50%), of the course test (10%), presentations (20%) and report (20%).
The student can get successful assessment (4 points) in the test and exam if at least 50% of the questions are answered correctly.
Each presentation is evaluated with 10 points, where the significance of the information is 30%, the logical presentation of the material - 30%, the interpretation of the obtained data - 30% and the presentation - 10%.
The report is evaluated with 10 points, where the significance of the presented information is 30%, the logical presentation of the material - 30%, the interpretation of the obtained data - 30% and the presentation - 10%.
