IMG204/3 Instrumental Food Analysis

Course Details

Synopsis

This course introduces the principles and applications of instrumental methods in food analysis. The covers spectrochemical analysis methods that use absorption of electromagnetic radiation (molecular ultraviolet-visible spectroscopy, fluorescence, infrared spectroscopy, atomic absorption/emission spectroscopy); chromatographic methods, such as HPLC and GC; thermal analysis, and electrophoresis methods. In all instrumental methods of food analysis discussed, aspects of instrumentation parts and practical considerations for qualitative and quantitative analysis such as sample preparation and sources of error will be discussed.

Course Objective

This course is designed to expose undergraduates to the understanding of the principles and theory of selected instrumental methods as used in food analysis.
