中文摘要: 以沙子空心李果干为研究对象，对其基本营养成分、矿质元素以及氨基酸进行测定与分析。结果表明：沙子空李果干中膳食纤维、灰分、总糖、总酸、总蛋白质、脂肪的含量分别为 8.06、1.7、57.4、0.141、0.86、0.2 g/100 g；维生素 C与烟酸含量分别为 1.22、0.382mg/100g；矿质元素含量大小顺序为 Ca＞Na＞Fe＞Zn＞Se，其中 Ca含量达到 5.33 mg/100 g；检测出16种氨基酸，苏氨酸含量最高为0.87 g/100 g，丙氨酸次之为0.23 g/100 g，酪氨酸最低，含量为0.026 g/100 g，从氨基酸评分中看出沿河沙子空心李的第一限制氨基酸是异亮氨酸，其中必需氨基酸总量/氨基酸总量（essential amino acid to total amino，EAA/TAA）为62.7%，必需氨基酸总量/非必需氨基酸总量（essential amino acid to non-essential amino acid，EAA/NEAA）为1.86，均高于国际粮油组织与世界卫生组织（Food and Argriculture Organization and World Health Oranization，FAO/WHO）提出的理想蛋白质的标准，说明沿河沙子空心李果干中的蛋白质是优质蛋白。
Abstract:The nutritions，mineral elements，and amino acids of Shazikongxinli dried fruits were tested and analysized.And results showed that the contents of dietary fibery，ash，total sugar，total acid，protein and fatty were 8.06，1.7，57.4，0.141，0.86，0.2 g/100 g，respecitvely；the vitamin C and niacin were 1.22 mg/100 g and 0.382 mg/100 g，respectivily；the high to low rank of mineral elements'contents were Ca，Na，Fe，Zn and Se，in witch the content of Ca reached 5.53 mg/100 g.Threonine content was highest at 0.87 g/100 g，followed by Ala at 0.23 g/100 g，and Tyr at the lowest at 0.026 g/100 g in 16 tested out amino acids，and Ile was the first restricted amino acids.Additionally，the essential amino acid to total amino（EAA/TAA）and essential amino acid to non-essential amino acid（EAA/NEAA）were 62.7%and 1.86 in separate，and both outweighed the standards of good protein raised out by Food and Argriculture Organization and World Health Oranization（FAO/WHO），which illustrated that the protein in Shazikongxinli dried fruits was good.
