摘要
为比较广西壮族自治区内3个澳洲坚果主栽品种(桂热1号、OC、695)5个不同生长期(即盛花期后155、165、175、185、195 d)果仁的脂肪酸组分,利用气相色谱-质谱联用仪(gas chromatography-mass spectrometer,GC-MS)分析其脂肪酸组分。结果表明:澳洲坚果果仁不同生长期均检测出18种脂肪酸并且含有人体必需脂肪酸,其含量受品种及其生长的影响显著(P<0.05),单不饱和脂肪酸(monounsaturated fatty acid,MUFA)的含量最高且遗传信息相对稳定;澳洲坚果果仁富含棕榈油酸,具有较高单不饱和脂肪酸/饱和脂肪酸值、多不饱和脂肪酸/饱和脂肪酸值和较低的致动脉粥样硬化指数、高胆固醇指数等特点。
3 main varieties of macadamia(Guire NO.1,OC and 695)were mainly cultivated in Guangxi.Fatty acid components of 3 main varieties of macadamia kernels,harvested at 5 different growth stages(days after flowers 155,165,175,185,195 d)were analyzed by gas chromatography-mass spectrometry(GC-MS).18 fatty acids were detected in macadamia kernels at different growth stages,including essential fatty acids,the content of which was significantly(P<0.05)affected by both variety and stage of growth.Macadamia kernels were found to be rich in palmitoleic acid and high ratios of monounsaturated acid/saturated acid,polyunstaturated acid/saturated acid,and low values of atherogenic index,hypercholesterolemic index.
