| 摘 要： | 以宣威火腿为对象,通过提取成熟宣威火腿的肌间脂肪和皮下脂肪,采用气相色谱-质谱联用法(GC-MS)对宣威火腿肌间脂肪与皮下脂肪中脂肪酸的组分进行探讨。结果表明:宣威火腿肌间脂肪中含11种饱和脂肪酸,占总脂肪酸的34.75%,15种不饱和脂肪酸,占总脂肪酸含量的64.78%,主要的脂肪酸为油酸(C18∶1)、棕榈酸(C16∶0)、硬脂酸(C18∶0)、亚油酸(C18∶2),含量分别为33.44%、23.37%、8.44%、20.55%;皮下脂肪中含11种饱和脂肪酸,占总脂肪酸的36.23%,15种不饱和脂肪酸,占总脂肪酸含量的63.47%,主要的脂肪酸为油酸(C18∶1)、棕榈酸(C16∶0)、硬脂酸(Cl8∶0)、亚油酸(C18∶2),含量分别为31.47%、21.90%、11.13%、22.39%。 |

| Abstract: | The fatty acid composition of intramuscular fat and subcutaneous fat in Xuanwei ham by GC-MS was studied.The results showed that Xuanwei ham contained 11 kinds of saturated fatty acids(SFA) and 15 kinds of unsaturated fatty acid(UFA).The relative percentage of SFA in intramuscular and subcutaneous fat was 34.75% and 36.23%,respectively.However,the relative percentage of UFA in intramuscular and subcutaneous fat was 6 4.78% and 63.47%,respectively.The main fatty acids in intramuscular fat and subcutaneous fat were oleic acid(C18∶ 1),palmitic acid(C16∶ 0),stearic acid(Cl8∶ 0) and linoleic acid(C18∶ 2).The relative percentages of above fatty acids in intramuscular fat were 33.44%,23.37%,8.44% and 20.55%,respectively.While,the relative percentages of above fatty acids in subcutaneous fat were 31.47%,21.90%,11.13% and 22.39% respectively. |
