Fat determination in Yoghurt and Curt Cheese using the Speed­Extractor E-916

Pressurized Liquid Extraction (PLE) is a well-established alternative for extracting lipids and/or various components faster and cheaper, but less frequently used for the verification of fat labels in food products. A reliable and fast procedure using PLE to determine the fat content in samples with easily accessible fat and high moisture content (above 50 %) is presented below. The extraction was carried out using the SpeedExtractor E-916 in combination with Multivapor™ P-12 for solvent evaporation in parallel. The fat content was determined gravimetrically.
