Extraction Unit E-816 ECE: Fat Determination in Animal Feed samples using Twisselmann extraction
Fat determination in animal feed samples

An effective procedure for fat determination in animal feed samples according to COMMISSION REGULATION (EC) No 152/2009 is presented. The sample is hydrolyzed prior the extraction. The Twisselmann extraction is performed with the Extraction Unit E-816 ECE (Economic Continuous Extraction).This allows the sample to be constantly kept in hot solvent vapor whilst efficiently rinsed with freshly distilled solvent. After the extract has been dried to a constant weight the total fat content is determined gravimetrically. The reference value was determined using Soxhlet extraction.
