Annotation -
The course contains the basic areas of food chemistry, physico-chemical, biochemical, sensory and other properties of individual components, their functions and major interactions and reactions which take place in foods during storage, culinary and technological processing. Students will be introduced mainly to the basic components of nutrition, ie proteins, fats and carbohydrates in their various forms, but also to essential dietary factors (vitamins, minerals) and antinutritional and toxic substances.

Requirements to the exam -

The exam consists of a written and oral part - within the scope of the syllabus.

The written part is mandatory, the oral part can only be taken after obtaining at least 50 points out of 100 in the written part - if less than 50 points are achieved, the exam is graded F.

If the oral part is unsuccessful, only this part can be repeated.

Learning outcomes -

After completing the course, the student will be able to:

Classify the basic chemical structures found in foods and food ingredients.

Define and use the terms main nutrients (macronutrients) and additional nutrients (micronutrients) in the correct contexts needed to describe the composition of foods and calculate their energy value.

Identify and systematically describe the representation and importance of amino acids in peptides and proteins

Identify and systematically describe the representation and importance of fatty acids in fats

Identify and systematically describe the representation and importance of monosaccharides in oligosaccharides and polysaccharides

Draw and describe simplified diagrams of chemical formulas of main nutrients. Explain the description of the formula to a second observer (student or teacher).

Determine groups of sensory active substances naturally present or intentionally added (as additives) to foods.

Describe and explain the difference between natural toxins and contaminants of foods and food ingredients.

Explain the connection between nutrients and antinutrients.

Lead a discussion on the above topics with regard to the use of this knowledge in nutritional therapy.

Solve simplified problems based on knowledge of reaction schemes of major nutrients within the scope of recommended sources and learning outcomes detailed for individual topics.

Assess possible chemical transformations of substances during technological and culinary processing of food raw materials and foods.
