Oil in Soybeans according to AOCS Ac 3-44

FatExtractor E-500 ECE: Determination of oil content in a soybeans sample by continuous extraction according to standard method AOCS Ac 3-44
Oil in Soybeans according to AOCS Ac 3-44

A simple and reliable procedure for the oil determination in a soybeans sample is introduced. This Application Note follows the official method AOCS Ac 3-44 by the American Oil Chemists` Society. The standard method requires an extraction with a Butt-type extraction apparatus with an extraction time of 5 h. The Butt-type extraction is equal to the Twisselmann extraction method used in the FatExtractor E-500 ECE.

Both, the Butt-type extractor as well as the Economic Continuous Extraction (ECE) 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.

This Application Note shows by means of a certified reference material sample that reliable and reproducible results will be received using the FatExtractor E-500 ECE. In a second step this Application Note shows that an extraction time of 1 h is sufficient to receive reliable and reproducible results for the oil determination in soybeans samples using the FatExtractor E‑500 ECE.
