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 with the basic components of nutrition, ie proteins, fats and carbohydrates in their various forms, but also with essential dietary factors (vitamins, minerals) and antinutritional and toxic substances.
