摘　　要：采用国标方法对黑斑蛙副产物脂肪、水分、蛋白质、矿物质元素等成分进行分析与评价。结果表明:黑斑蛙副产物中共检测出16种氨基酸,其中必需氨基酸7种,蛙头、蛙皮以及蛙内脏中总氨基酸含量分别为11.00%、15.90%、30.60%。3种原料中,单不饱和脂肪酸分别占脂肪酸总量的43.80%、51.84%、41.26%;多不饱和脂肪酸分别占脂肪酸总量的26.66%、20.43%、26.75%;总体来说黑斑蛙副产物中主要脂肪酸为棕榈酸、油酸、亚油酸。检测了5种矿物质元素和4种维生素,常量元素和微量元素含量最高的分别为钙元素和铁元素;VE在3种副产物中的含量分别为1.41、1.62、3.85 mg/100 g。黑斑蛙副产物中油脂及蛋白质含量较为丰富,在功能性食品、食品添加剂、调味品、饲料和宠物食品等方面具有应用潜力。According to the national standard,the composition of fat,water,protein,mineral elements and other components of the frogs were analyzed and evaluated.The results showed that a total of sixteen amino acids were detected in the by-products of the frog,including seven essential amino acids,and the total amino acid contents in the frog head,frog skin and frogs viscera were 11.00%,15.90%and 30.60%,respectively.Among the three raw materials,monounsaturated fatty acids accounted for 43.80%,51.84%,and 41.26%of the total fatty acids;polyunsaturated fatty acids accounted for 26.66%,20.43%,and 26.75%of the total fatty acids,respectively;the main fatty acids in the product are palmitic acid,oleic acid and linoleic acid.Five kinds of mineral elements and four kinds of vitamins were detected,and the highest content of macro and trace elements were calcium and iron respectively;the content of vitamin E in the three by-products were 1.41 mg/100 g,1.62 mg/100 g,3.85 mg/100 g,respectively.The by-products of frogs are rich in oil and protein,and have potential in the development of functional foods,food additives,condiments,feed and pet food.
