Fatty Acid Composition of the Monoglycerides from Lipolyzed Milk Fat

The monoglycerides from eight samples of lipolyzed milk fat were converted to allyl esters and identified by gas-liquid chromatography. Fresh milk fat did not contain monoglycerides detectable by the methods used. The majority of the samples contained butyrate through stearate and oleate. Many contained Clo-C16 monounsaturates, C9-C17 saturates, and linoleate, and up to eight additional unidentified esters. The fatty acids present in largest quantity, reported as per cent by weight of total allyl esters, were: palmitate--31.2, oleate--17.7, myristate--15.6, caprate--5.7, palmitoleate--5.6, linoleate---4.1, laurate--4.0, and stearate---3.9. The patterns were distinctly different from the reported fatty acid composition o intact milk fat.
