IMG203/3 Chemical Food Analysis
- Credit: 3
- Semester: 1
- Prerequisite: IMG103 Food Chemistry (pass)
The course introduces the basic principles and procedures commonly used for the analysis of major food components. The concepts involved in sampling protocols and the preparation, reporting and analysis of data to achieve valid measurement are emphasized. The course covers topics on proximate analysis of the major food components (moisture, ash, nitrogen or protein, lipid, carbohydrate) and analysis methods for other food components such as vitamin C, preservatives such as benzoic acid, sulphur dioxide etc. Practical experience of relevant experimental procedures will be conducted.
This course is designed to expose undergraduates to the basic principles of various chemical methods of compositional analysis and their application to the analysis of specific food components e.g. proteins, fats, moisture, carbohydrates, and minerals.
