Gravimetric fat determination of liquid dairy samples by parallel evaporation after extraction following the Mojonnier method (ISO 1211:2010)
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 evaporation 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.
