Determination of oil in fish meal

FatExtractor E-500 ECE: determination of oil content in a fish meal sample by continuous extraction according to AOCS Ba 3-38
Determination of oil in fish meal

A simple and reliable procedure for the oil determination in a fish meal sample is introduced. This Application Note follows the official method AOCS Ba 3-38 by the American Oil Chemists’ Society. The standard method AOCS Ba 3-38 requires an extraction with a Butt-type extraction apparatus. The Butt-type extraction is equal to the Twisselmann extraction method used in the FatExtractor E-500 ECE. Both are continuous extractions where the sample is constantly kept in hot solvent vapor whilst efficiently rinsed with freshly distilled solvent. The oil content is determined gravimetrically after the extract has been dried to a constant weight.
