Extraction and Characterization of Lipids
There are some key factors which determine
the chemical and physical properties of fats and oils include the degree of
unsaturation or iodine value, the type of unsaturation (cis or trans), and the weight-average molecular weight
or saponification number. Fats and oils commonly undergo processes such as
hydrogenation, oxidation; which modify the physical and chemical characteristics
of fats and oils by changing the iodine value and cis/trans ratio, for which specific values are often targeted. Hence
monitoring changes in these values during a process is important because they
define the quality of the end product. In addition, the trans content may be limited by regulations because of its
association with heart disease and may be a required analysis for labeling. (Li, van de Voort, Sedman & Ismail, 1999)
