Abstract:

 
HEEP COPYRIGHT: BIOL ABS. Using a combination of gas-liquid chromatography and mass spectrometry, the presence of 39 aliphatic hydrocarbons was firmly established in the unsaponifiable fraction of anhydrous milk fat. The hydrocarbons were the C14-C27 and the C29-C31 straight-chain paraffins, their monoolefin analogs, and the C25-C29 branched alkanes. Phytene (3,7,11,15-tetramethyl-n-hexadec-2-ene), identified for the 1st time in milk fat, was isolated and identified by high-resolution mass spectrometry and IR analysis. The total hydrocarbon content amounted to 30 ppm of the milk fat. Polychlorinated biphenyls also were detected in trace amounts in the area of the chromatogram between the C18 and the C23 hydrocarbons.
