✦ Synopsis
Soxhlet method was used in hot and standard extraction mode and compared with liquid}liquid extraction methods for lipid determination in food samples. Several solvent mixtures were investigated and Soxhlet extraction time was optimized. Soxhlet extraction was convenient only for solid samples. Except Roese}Gottlieb method, other liquid}liquid extraction methods were suitable for lipid extraction from all samples analysed. Even if the precision of each method was good (R.S.D.(3.5%), the comparison of extracted lipid amounts showed that, depending on the type of sample, some methods present serious limitations.
