Abstract: | Intramuscular fatty acids content and composition of Australian imported Black Angus beef raised in Ujinmqin grassland were analysised in this experiment to provide basic data for future breeding,crossbreeding,and meat quality evaluation.Target samples were taken of tenderloin,nates,shoulder clod,ribloin,highrib,brisket and topside from seven Black Angus beef which were Australian imported and raised in Ujinmqin grassland,with mean weights of (500±38)kg.The high efficient fatty acids extraction method and gas chromatograph (GC) were used to determine the content and composition of intramuscular fatty acids.Then the resuls were compared with FAO/WHO recommended values.The results showed that,the SFA content in target samples of Black Angus beef followed from high to low as:tenderloin,highrib,ribloin,shoulder clod,brisket,nates,topside.Moreover,majorities of intramuscular fatty acids composition were palmitic acid and stearic acid.The most highest content in MUFA was oleic acid;large amount of linoleic acid and linolenic acid were found in PUFA;The highest ratio of P/S and M/S were shown in nates,and the ratio of n-3/n-6 was 0.85.It was concluded that the meat of Australian imported Black Angus beef raised in Ujinmqin grassland had good flavor and high nutritive value. |
