FAME may be also obtained plump hardcore directly by transesterification (alcoholysis or methanolysis) of the fatty acid-containing lipids. The extraction and methylation may also be combined in a one-step procedure, this is particularly recommended for very small samples in order to prevent any loss of fatty acids during the plump hardcore classical procedures. Saponification When fatty acids are required in free form for plump hardcore further analysis, lipids (present as glycerides, glycerophosphatides, glycosyldiglycerides, sterol esters or waxes) are first hydrolyzed in alkaline medium allowing to extract also the unsaponifiable material if present in the crude lipid mixture (sterols, alcohols, hydrocarbons, pigments, vitamins...).
Unfortunately, a progressive and rapid loss of sensitivity occurred with decreasing fatty acid chain length. Thus, it was necessary to determine the response factors for each fatty acid in relation to an internal standard (C17). Advantages of that extraction procedure are the little sample preparation, the food and-drink absence of organic solvents, the detection of short chain fatty acids, and a good reproducibility. Application of gas chromatography coupled to mass spectrometry following headspace solid-phase microextraction was applied with great accuracy and sensitivity to the determination of free volatile fatty food and-drink acids in aqueous samples (Abalos M food and-drink et al., J Chromatogr A 2000, 891, 287). Valuable results were obtained for the determination of C2-C7 fatty acids in raw sewage.
