| 中文摘要: |
| 测定了蒜头果种仁的蛋白质含量、粗脂肪含量及蒜头果种仁油脂肪酸组成和矿质元素含量，并采用氨基酸自动分析仪测定蒜头果种仁的氨基酸组成，对其氨基酸营养价值进行评价。结果表明：蒜头果种仁蛋白质含量为21.02%，粗脂肪含量为61.05%，蒜头果种仁油中共检出17种脂肪酸，包括5种饱和脂肪酸和12种不饱和脂肪酸，其中神经酸的含量最高，为45.04%；蒜头果种仁含有17种氨基酸，其中7种为必需氨基酸，其氨基酸比值系数分（SRC）为77.25，营养价值较高；蒜头果种仁中含有K、P、Mg、S、Ca、Fe、Mn等矿质元素。蒜头果种仁营养成分丰富，可进一步加强其资源化利用。 |
| 英文摘要: |
| The content of protein and oil of Malania oleifera seed kernel, and the fatty acid composition and mineral element content of Malania oleifera seed kernel oil were determined. In addition, the amino acid composition of the seed kernel was determined by an automatic amino acid analyzer, and the nutritional value of the amino acids was evaluated. The results showed that the protein content of Malania oleifera seed kernel was 21.02%. The oil content was 61.05%. 17 fatty acids were determined from the oil, including 5 saturated fatty acids and 12 unsaturated fatty acids, in which the content of nervonic acid was the highest, reaching 45.04%. Malania oleifera seed kernel contained 17 kinds of amino acids, in which 7 kinds were essential amino acids, and its score of amino acid ratio coefficient (SRC) was 7725, indicating higher nutritional value of Malania oleifera seed kernel. Malania oleifera seed kernel contained mineral elements, such as K、P、Mg、S, Ca、Fe and Mn. Malania oleifera seed kernel was rich in nutrients, and could be further enhanced for their resource utilization. |
