摘要
分析中国大鲵肌内脂肪酸的组成,并研究肌内脂肪酸抗氧化,提供肌内脂肪酸开发利用的基础理论。通过气相色谱/质谱联用技术分析肌内脂肪酸的组成;通过Schaal烘箱法(63±1℃)研究肌内脂肪酸的抗氧化特性。GC-MS分析结果表明:肌内脂肪主要含13种脂肪酸,其含量由高到低依次为,C18∶124.2%,C16∶015.4%,C16∶113.7%,C18∶28.2%,C20∶56.7%,C18∶34.5%,C22∶64.3%,C14∶13.0%,C18∶02.8%,C22∶52.6%,C20∶42.2%,C17∶02.0%,C17∶11.9%。饱和脂肪酸(SFA)为20.2%,不饱和脂肪酸(UFA)达71.3%。单不饱和脂肪酸(MUFA)为42.8%,多不饱和脂肪酸(PUFA)为28.5%,具有保健功能性作用的ω-6型PUFA为13.0%,ω-3型PUFA为15.5%。ω-6型与ω-3型PUFA比为0.8。Schaal烘箱法研究结果表明:抗氧化剂二丁基对甲苯酚(BHT)、没食子酸丙酯(PG)、特丁基对苯二酚(TBHQ)对肌内脂肪酸有明显的抗氧化作用,其中特丁基对苯二酚抗氧化效果较佳。中国大鲵肌内脂肪富含ω-3和ω-6型PUFA,极具营养和保健功能。特丁基对苯二酚(TBHQ)对肌内脂肪酸有显著的抗氧化作用。
The muscle oil fatty acids composition and antioxidation of Chinese giant salamander were studied. Muscle fatty acids were analyzed with GC6890N/MSD5973N.Antioxidation research was made in oven（63 ± 1℃）. Several antioxidants （ BHT, PG, TBHQ） were added to the muscle oil. GC- MS results showed muscle oil mainly contain 13 kinds fatty acids. In turn, they were c18：124.2%,C16：0,15.4%,C16：113.7%,C18：28.2%,C20：56.7%,C18：34.5%,C22：64.3%,C14：113.0%,C18：02.8%,C22：52.6%,C20：42.2%,C17：002.0%,C17：1.9%.Saturated fatty acids （ SFA ） and unsaturated fatty acids （UFA） amount was as follows： SFA 20.2%, UFA 71.3%, monounsaturated fatty acids （MUFA）42.8%, polyunsaturated fatty acids（PUFA） 28.5%, ω-6 PUFA 13.0% ,ω-3 PUFA 15.5% ,ω-6 and ω-3 PUFA ratio 0.8.The antioxidation results showed butylated hydroxytolene（BHT）, propyl gallate （PG）, and tertiary butylhydroquinonoe（TBHQ） were all effective antioxidants.TBHQ was more effective than any others.Chinese giant salamander muscle oil contain abundant ω-3 and ω-6 PUFA.Chinese giant salamander muscle oil nutrition and health function were high.Tertiary butylhydroquinonoe（TBHQ）were more effective antioxidant than any others.
