摘　　要：为了促进铁力木的开发利用,以铁力木种仁为材料,对其脂肪、水分、蛋白质、可溶性糖、氨基酸、矿物质元素、维生素以及铁力木种仁油的脂肪酸组成及含量进行了分析。结果表明:铁力木种仁中脂肪、水分、蛋白质和可溶性糖的含量分别为58.60、7.90、7.34 g/100 g和4.44 g/100 g;铁力木种仁油中共检出9种脂肪酸,其中饱和脂肪酸5种,含量为32.64%,不饱和脂肪酸4种,含量为66.76%,4种含量最高的脂肪酸分别为油酸(49.10%)、亚油酸(17.30%)、棕榈酸(15.80%)和硬脂酸(15.40%);铁力木种仁中共检出16种氨基酸,7种必需氨基酸含量占总氨基酸含量的39.48%,必需氨基酸与非必需氨基酸的比值为65.24%,必需氨基酸比值系数分(SRC)值为51.78;在检测的9种矿物质元素(铜、锌、铁、锰、钙、镁、磷、硒、钾)中,常量元素和微量元素中含量最高的分别为钾和铁;维生素E的含量为10.57 mg/kg,未检出维生素A。综上,铁力木种仁中油脂、微量营养成分等的种类和含量较为丰富,可在开展动物食用安全性实验证实无毒后,作为一种全新的坚果食品加以开发。In order to promote the development and utilization of Mesua ferrea L.,the fat,moisture,protein,soluble sugar,amino acid,mineral element,and vitamin of Mesua ferrea L.seed kernel and fatty acid composition and content of the seed kernel oil were analyzed.The results showed that the contents of fat,moisture,protein and soluble sugar in Mesua ferrea L.seed kernel were 58.60,7.90,7.34 g/100 g and 4.44 g/100 g,respectively.Nine kinds of fatty acids were detected,of which five were saturated fatty acids,accounting for 32.64%of the total fatty acid content.There were four kinds of unsaturated fatty acids,accounting for 66.76%of the total fatty acid content.The four fatty acids with the highest content were oleic acid(49.10%),linoleic acid(17.30%),palmitic acid(1580%)and stearic acid(15.40%).Sixteen kinds of amino acids were detected,and seven kinds of essential amino acids accounted for 3948%of the total amino acids.The ratio of essential amino acids to non-essential amino acids was 65.24%,and the score of ratio coefficient of essential amino acids(SRC)was 51.78.Nine mineral elements(Cu,Zn,Fe,Mn,Ca,Mg,P,Sn,K)were detected,and the contents of K and Fe were the highest in macroelements and trace elements,respectively.The content of vitamins E was 10.57 mg/kg,and vitamins A was not detected.In conclusion,the types and contents of oil and trace nutrient in Mesua ferrea L.seed kernel are relatively rich,which can be developed as a new nut food after the safety test of animals proves that it is non-toxic.
