• Resumen

  • The aim of the present work is to apply the different kinds of techniques such as:

    classical gas chromatography, gas chromatography/mass spectroscopy and high speed gas chromatography for the characterization of a range of animal fats.

    A comprehensive study of the different techniques applicable to the characterization of triacylglicerols (TAGs) in animal fats, especially in Finnish dear and Baltic ringed seal has been performed. The results obtained show that recent developments include variations and improvements of well established procedures, and the discovery and application of new reagents.

    An essential prerequisite for the analysis of lipid-mixtures of biological origin, by gas chromatography, is the quantitative formation and isolation of the constituent methyl esters (Stoffel et al 1959). Recent developments include variation and improvements of well established procedures and the discovery and application of new reagents.

    The research has been focused on the application of those variations and improvements, and specially on the use of Methelute (Pierce 2002) as well as the utilization of iodine (Ramalinga 2001), that is a practical and useful Lewis acid catalyst for the esterification of carboxylic acids with alcohols.
