Fat determination in dairy products by ECE

Fat content in different dairy samples was determined. The samples were hydrolyzed using the HydrolEx H-506 and extracted on the FatExtractor E-500 ECE. The Economic Continuous Extraction (ECE) is a continuous extraction where the sample is constantly kept in hot solvent vapor whilst efficiently rinsed with freshly distilled solvent, this extraction method is also called Twisselmann. The total fat content is determined gravimetrically after the extract has been dried to a constant weight.
