| Résumé : |
This work presents the results of a Gas Chromatography methodology used to characterize and quantify the major fatty acids of bovine tallow. Tallow is a byproduct from processing waste meat in slaughterhouses and from tannery waste. Tallow has a high commercial value, especially when fractionated to olein that is predominantly composed of unsaturated fatty acids. Olein is used as a raw material for the production of leather fatliquoring emulsions or biodiesel production. The fatty acids of tallow and its products of fractionation were first converted to methyl esters, and these esters were then analyzed by Gas Chromatography. The results showed the major fatty acids and their weight distribution. This analytical methodology will allow a quality assessment of tallow by the end user industry. It is also a reliable quantitative tool to evaluate the efficiency and optimization of the tallow fractionation processes. |
