Cheese and processed cheese products — Determination of fat content — Gravimetric method (Reference ...
Describes a method based on the Schmid-Bondzynski-Ratzlaff principle which consists in digesting a test portion with hydrochloric acid, adding ethanol and subsequently extracting the acid-ethanolic solution with diethyl ether and light petroleum, removing the solvent by distillation or evaporation, and determining the mass of the substances extracted which are soluble in light petroleum. The…
