不同品种养殖大黄鱼肌肉结构及蛋白组成分析

Analysis of the Muscle Structure and Protein Composition of Different Varieties of Cultured Large Yellow Croaker (Larimichthys crocea)

  • 摘要: 为探究不同品种养殖大黄鱼的食用品质差异,本研究以‘东海1号’‘甬岱1号’‘富发1号’‘浙江传统品种’及‘宁德传统品种’为对象,对其肌肉结构及蛋白组成进行测定分析。结果表明,不同品种大黄鱼的基本营养成分存在一定差异,‘富发1号’肌肉粗蛋白含量显著高于其他4个品种,而‘浙江传统品种’的粗脂肪含量最低,仅有2.77%;‘甬岱1号’大黄鱼肌纤维密度最高,是‘宁德传统品种’大黄鱼肌纤维密度的1.43倍;5个品种大黄鱼的肌纤维横截面积由大到小排序为‘浙江传统品种’>‘宁德传统品种’>‘富发1号’>‘东海1号’>‘甬岱1号’,低场核磁共振也发现‘甬岱1号’不易流动水具有较小的弛豫时间;‘富发1号’大黄鱼肌肉中盐溶性蛋白含量最高,为‘东海1号’的1.29倍,5个品种大黄鱼水溶性蛋白含量在58.72~74.85 mg/g之间,而凝胶电泳结果表明不同品种大黄鱼的肌肉蛋白分子量分布无显著差异;5个品种大黄鱼肌肉的亮氨酸、赖氨酸、苯丙氨酸和酪氨酸含量均高于WHO/FAO标准。本研究从食品原料学角度系统分析了不同品种养殖大黄鱼的肌肉结构及蛋白组成差异,为后续良种选育和高质加工提供参考。

     

    Abstract: To investigate the differences in edible quality among different varieties of cultured large yellow croaker, this study focused on 'Donghai 1' 'Yongdai 1' 'Fufa 1' 'traditional Zhejiang variety', and 'traditional Ningde variety', analyzing their muscle structure and protein composition. The results showed certain differences in the basic nutritional composition among the various varieties. The crude protein content in the muscle of 'Fufa 1' was significantly higher than that of the other four varieties, while the 'traditional Zhejiang variety' had the lowest crude fat content, at only 2.77%. The muscle fiber density of 'Yongdai 1' was the highest, being 1.43 times that of the 'traditional Ningde variety'. The cross-sectional area of the muscle fibers of the five varieties ranked from largest to smallest as follows: 'traditional Zhejiang variety'>'traditional Ningde variety'>'Fufa 1'>'Donghai 1'>'Yongdai 1' . Low-field NMR also revealed that the immobile water in 'Yongdai 1' had a shorter relaxation time. The salt-soluble protein content in the muscle of 'Fufa 1' was the highest, being 1.29 times that of 'Donghai 1'. The water-soluble protein content among the five varieties ranged from 58.72 mg/g to 74.85 mg/g, while the electrophoresis results showed no differences in the muscle protein molecular weight distribution across different varieties. The leucine, lysine, phenylalanine, and tyrosine contents in the muscles of all five varieties were higher than the WHO/FAO standards. This study systematically analyzed the differences in muscle structure and protein composition among different varieties of cultured large yellow croaker from the perspective of food material, providing a reference for subsequent variety selection and high-quality processing.
