Course contents:
The course consists of weekly lectures and one laboratory exercise. The lectures deals with structure and properties of the main macro- and micronutrients in various raw materials (proteins, lipids, carbohydrates including polysaccharides, vitamins and minerals) and additives. Special emphasis is placed on the functional properties of proteins and polysaccharides  and on lipids melting properties and stability against oxidation.. The course is taken together with the laboratory course KJB201 and the various theme coordinated with topics KJM110 and KJB200.
Learning outcome:

Students will learn about the structure and function of macro- and micronutrients in various raw materials for food (proteins, lipids, carbohydrates including polysaccharides, vitamins and minerals) and additives. and water Special emphasis on functional properties of proteins and polysaccharides and lipids melting properties and stability against oxidation.

Water: Recognize water's structure and properties, the terms free and bound water, correlation between water content (%), water activity and durability

Proteins: Understand the relationship between amino acid composition, protein structure and properties, understanding how denaturation affecting properties, know the most important functional properties (solubility and water binding, surfactant properties (foam and emulsions), gelling and viscosity)

Carbohydrates: Understandi the relationship between composition and structure and properties, know the most important functional properties (solubility and water binding ,, gelling and viscosity)

Lipids: Understand  the structure and properties of neutral and polar lipider, the relationship between fatty acid composition and properties of triacylglycerols, fatty acid composition of vegetable and animal lipids and how this affects properties such as melting point and stability against oxidation.

Minerals: Know the terms "main elements", "trace elements" and "ultra-trace", various factors that affect the bioavailability of various minerals.

Vitamins: Know the uike factors affecting the content of the various products and the optimization of vitamin content.

Additives: Know the purpose of use of additives, different groups of substances and their function, possible unwanted health effects of certain compounds and rregulations regarding use.

Learning activities:
Lectures. Exercises in laboratories (with intensive guidance). Writing of journals. Colloquia and individual study.
