摘　　要：为了进一步挖掘鳄鱼肉的营养价值,以鳄鱼肉、猪肉、牛肉、鸡肉、羊肉、河虾肉和鲫鱼肉为研究对象,采用国家标准检测方法,分析和测定其含有的主要营养成分并进行营养评价。结果表明:与其他肉类相比,鳄鱼肉中磷含量最高;鳄鱼肉中钙含量显著高于其他畜禽肉(P<0.05),是一种优质补钙食品,鳄鱼肉中水溶性维生素含量最高,鲜味氨基酸含量最高,尤其是谷氨酸含量;根据必需氨基酸评分和化学评分,鳄鱼肉更易被人体消化吸收;鳄鱼肉多不饱和脂肪酸(polyunsaturated fatty acid,PUFA)含量极其丰富,尤其是n-6和n-3 PUFA含量明显高于其他畜禽肉类。因此鳄鱼肉肉质鲜美,营养价值高,是一种优质的肉类食材。In order to explore the nutritional value of crocodile meat,the main nutrients in crocodile meat,pork,beef,chicken,mutton,river prawn and crucian carp meat were analyzed and evaluated using Chinese national standard methods.The results showed that compared with other meats,crocodile meat had higher phosphorus content.The calcium content in crocodile meat was significantly higher than that in other livestock and poultry meats(P<0.05),indicating that crocodile meat is a high-quality calcium supplement food.Compared with other meats,crocodile meat had higher contents of watersoluble vitamin umami amino acids,especially glutamic acid.According to the essential amino acid score(AAS)and chemical score(CS),crocodile meat was more easily digested and absorbed by the body.Polyunsaturated fatty acids(PUFAs)were abundant in crocodile meat.Particularly,the contents of n-6 and n-3 PUFA in it were significantly higher than those in other livestock and poultry meats.Therefore,crocodile meat is delicious and has high nutritional value.It is a high-quality meat.
