NFOK14018U Advanced Food Chemistry
MSc Programme in Food Science and Technology
MSc Programme in Food Innovation and Health
The course focuses on the chemical reactions that affect quality and stability of foods during their storage and handling. The molecular mechanisms of important reactions in foods and beverages will be introduced and discussed using chemical and physical thermodynamic and kinetic principles. Central topics will include: 1) Water and minerals in foods. 2) Kinetics of complex reaction mechanisms. 3) Packaging: Interactions between food and the nearest surroundings. 4) Lipid oxidation and antioxidants in heterogeneous food matrices. 5) Oxidation and other chemical modifications of proteins. 6) Pigments and light induced reactions.
The course will include theoretical introduction to standard analytical and advanced experimental procedures for characterization of food chemical instability.
After completing the course the student should be able to:
- Describe the reactions at a molecular level that occur during common chemical food deteriorating phenomena.
- Classify structures and properties of components, ingredients and of chemical reactions that are central in relation to food quality changes.
- Display overview of specific changes of food components during storage and handling and how to use analytical methods to describe these changes.
- Suggest specific analytical methods that are relevant for describing chemical changes of food quality.
- Use thermodynamic and kinetic principles to explain the mechanisms, which cause modifications or formation of specific components in foods.
- Suggest preventive measures against food quality changes based on theoretical chemical knowledge.
- Reading and using original scientific literature, and communicate the obtained knowledge.
- Interpret and discuss chemical and physical analytical data in relation to food stability.
- Evaluate stability and predict changes of food chemical quality based on experimental data in combination with knowledge from scientific literature.
See Absalon for a list of course literature. It will include book chapters, collection of reviews, and original scientific literature.
