摘  要:本实验测定了腊肉中脂肪酸的组成,腊肉中主要脂肪酸有9c18:1(38.2%~43.76%)、c16:0(20.80%~22.30%)、9c12c18:2(10.03%-12.19%)、18:0(7.31%~9.59%)、9c16:1(1.72%-1.98%)币日c14:0(1.16%~1.17%)。腊肉中饱和脂肪酸与多不饱和脂肪酸的比例为2:1。瘦腊肉中CLA达到0.448%,比肥腊肉中CLA(0.272%)高。腊肉中反式脂肪酸主要是9t18:(0.20%-0.50%)和11t18:1(0.30%-0.79%)。瘦腊肉的n-6/n-3达到8.054,而肥腊肉的n-6/n-3只有1.480。The fatty acids in Cured meat were determined. The results showed that the main FFAs in cured meat ham were 9c18:1(38.2% -43.76%), 16:0(20.80% - 22.30%), c18:2(10.03% - 12.19%), c18:0 (7.31% 9.59%), 9c16:1 (1.72% - 1.98%), and c14:0 (1.16% - 1.17%). The ratio of saturated fatty acids to polyunsaturated fatty acids was 2:1. CLA in intramuscular lipids reached 0.488%, while in adipose tissue was 0.272%. The main trans fatty acids were 9 t18:1(0.20% -0.50% ) and 11 t18:1 (0.30% -0.79% ). The ratios of n-6 to n-3 in intramuscular lipids and adipose tissue were 8.054 and 1.480, respectively.
