The determination of fat in food is a routine procedure used in quality assurance and for labelling. Below, a simple and easy procedure for fat determination in yogurt, according to §64 LFGB L 01.00-20 is introduced. The sample is hydrolysed with hydrochloric acid using the Hydrolysis Unit E-416, followed by a Twisselmann extraction with the Extraction Unit E-816
