Parallel evaporation after extraction of liquid dairy samples following the Mojonnier method (ISO 1211:2010) – gravimetric fat determination

The fat in liquid dairy samples is usually extracted with an organic solvent that is then evaporated to complete dryness prior to gravimetric analysis. In this short note, initial conditions and evaporation settings for the parallel evporation of milk fat dissolved in diethyl ether / light petroleum are presented. These settings have been optimized for fast and accurate results with simultaneously high solvent recoveries.
