摘要
测定了贵州地区池塘养殖白斑狗鱼的含肉率及其肌肉生化成分。试验结果表明,白斑狗鱼的含肉率为59.64%;其肌肉生化成分(鲜质量百分比),水分77.5%、蛋白质18.3%、脂肪1.2%、灰分1.2%。肌肉中含有17种氨基酸,总含量为16.55%;7种必需氨基酸含量为6.79%,占氨基酸总含量的41.03%;4种鲜味氨基酸总量为5.077%,占总氨基酸含量的30.67%;必需氨基酸指数为77.24,赖氨酸含量丰富(1.914%),占氨基酸总量的11.56%,蛋氨酸、胱氨酸和缬亮氨酸为限制性氨基酸。
The Dressed ratio and nutrient composition were measured in muscle of northern pike Esox lucius cultured in a pond in Guizhou province.The Dressed ratio was found to be 59.64%,the moisture 77.5%,the crude protein 18.3%,the crude fat 1.2%,and the crude ash 1.2%.The total content of 17 amino acids was 16.55%,including 6.79% of 7 essential amino acids,accounting for 41.03 % of the total amino acids,and 5.077% of 4 delicious amino acids,comprising of 30.67% in the total amino acids.The essential amino acid index(EAAI) was found to be 77.24,Lysine level of about 1.914%,accounting for 11.56% of the total amino acids,and Met,Ileucine and Cys the limited amino acids.
