Abstract
A modification of the Roese Gottlieb method for the extraction of milk fat for gaschromatographic analysis consisted of the use of hexane: ethyl alcohol instead of diethyl ether. This method was compared to the original one and the same fat quantity was obtained, but a higher amount of the saponificable fraction was extracted with hexane. Hexane was supposed to have a selective power of extraction on lipids. This method has a number of advantages over the common use of diethylether, as lower volatility or peroxides freeFile in questo prodotto:
