Abstract
Direct esterification of lipids in foods, including liquid and powder infant formulae, can be used as a simplified analytical procedure for the analysis of long-chain polyunsaturated fatty acids. The new method gives comparable results to standard methods using lipid extraction, but with less effort. The gas chromatographic separation method descri bed uses an internal standard to calculate not only the normalised amo unt of fatty acid/total fatty acids, but also the absolute amounts of fatty acids in the product.
