Summary

Two methods are recommended for preparing fatty acid methyl esters from olive oils and olive-pomace oils: Method A (trans-esterification with cold methanolic solution of potassium hydroxide) and Method B (methylation by heating with sodium methylate in methanol followed by esterification in acid medium). Method A is applied to samples of certain oil categories, while Method B is applied to samples with a free fatty acid content of more than 3.3%. Purification of oil samples is necessary in some cases, using a silica gel column or solid-phase extraction on silica gel phase cartridges. The methods are used for determining ∆ECN42, fatty acid composition, and trans-isomers of fatty acids.
