β¦ Synopsis
Comprehensive chromatography in the characterisation of edible oils and fats
The analysis of oils and fats is based almost entirely on chromatography sometimes linked to a spectroscopic procedure. This review covers multidimensional methods using two of GC, LC, and SFC which together provide a much higher resolving power. The combination of detailed profiling methods with chemometrics offers a new rote to understanding product properties and how these are related to fatty acid composition. Comprehensive chromatography is a new development with growing potential. Some procedures require instrumental improvements but others such as GC6GC are ready for use now.
