Title: Methods for analysis of milk-based products — Determination of fat content of milk-based edible ices and ice mixes by the Weibull-Berntrop gravimetric method
This British Standard specifies a reference method for the determination of fat content in:
Milk-based edible ices (e.g., ice cream, frozen desserts)
Ice mixes (premixes intended for freezing)
The method is based on the Weibull-Berntrop gravimetric technique, which involves:
Acid digestion of the sample to release fat
Solvent extraction of fat using diethyl ether and petroleum ether
Gravimetric measurement of extracted fat content
