The eggs of Sansui's characteristic sheldrake duck were re-searched to enrich its foundation and deepen the objective evaluation. Moisture content,crude protein content,amino acid composition and its content,crude fat content,composition and content of fatty acids,cholesterol content and the content of calcium,zinc,magnesi-um,iron,copper,manganese,lead and selenium of 3 kinds of egg samples in Guizhou were determined by the methods of China national standard,chromatography of gases,Inductively coupled plasma atomic emission spectrometry and spectrofluorimetry.Amino acid and fatty acids were scientifically evaluated by the method WHO/FAO Amino Acid Scoring Model,the chemical score and the Thrombus index used internationally.The results showed that the contents of protein,fat, cholesterin, and Ca,were 11.97%, 12.81%,498.55 mg/100 g,and 504.17 mg/kg,respectively.Moreo-ver,the score of amino acids was above 100,and the AI and TI val-ues were 0.36 and 0.79 respectively.The results showed that the eggs of Sansui's characteristic sheldrake duck had the property of higher amino acid and fatty acid value,and content of mineral,and lower incidence of atherosclerosis and thrombus were found in them.%为加深对三穗麻鸭的基础研究,完善对三穗鸭蛋的客观评价,以三穗鸭蛋为研究对象,通过国标、气相色谱法、电感耦合等离子体发射光谱法和荧光光度法等方法,对贵州三穗特色麻鸭蛋进行水分、粗蛋白含量、氨基酸组成及其含量、粗脂肪含量、脂肪酸组成及其含量、胆固醇含量和钙、锌、镁、铁、铜、锰、硒7种矿物质含量的测定,并采用国际上通用的WHO/FAO 氨基酸评分模式、化学评分、致血栓指数等评价方法对氨基酸和脂肪酸进行科学评价.得出三穗麻鸭蛋粗蛋白含量11.97%,粗脂肪含量12.81%,胆固醇含量498.55 mg/100 g,钙含量504.17 mg/kg,氨基酸评分均大于100分,AI、TI指数分别为0.36和0.79,具有氨基酸、脂肪酸价值高,矿物质含量高,致动脉粥样硬化与血栓几率低的特点.
