摘要: 以鲢鱼鱼糜为研究对象,通过测定凝胶强度、持水性、蒸煮损失率、色度、质构特性、水分分布状态、 微观结构和蛋白质分子质量分布指标,分析了漂洗过程中锌离子对鲢鱼鱼糜凝胶特性的影响。结果表明,用含有 锌离子的漂洗液漂洗较用清水漂洗和质量分数0.15% NaCl漂洗对鲢鱼鱼糜凝胶性能有较大改善,其中,当锌离子 浓度为6 μmol/L时,鲢鱼鱼糜凝胶的凹陷距离、凝胶强度和咀嚼度均处于最大值(8.47 mm、2 325.90 g·mm、 2 752.12 g·mm);破断力为274.74 g,较清水漂洗提高了14.95%;该浓度条件下凝胶对水的束缚能力增强,持水 性达到最大值(83.13%),并且蒸煮损失率和横向弛豫时间T23为最小值(分别为9.39%、45.47 ms);白度得到提 升。在锌离子的作用下,肌球蛋白重链通过交联作用形成较大聚集体,且凝胶微观结构均匀致密。

Abstract: The effect of zinc ions in rinsing solution on gel properties of silver carp surimi including gel strength, waterholding capacity, cooking loss percentage, whiteness, texture properties, moisture distribution, microstructure, and protein molecular mass distribution was investigated. It turned out that rinsing with zinc solution greatly improved the properties of surimi gel compared with water and 0.15% (m/m) NaCl solution. The highest deformation (8.47 mm), gel strength (2 325.90 g·mm) and chewiness (2 752.12 g·mm) were observed at a zinc concentration of 6 μmol/L. Breaking force of surimi gel rinsed with 6 μmol/L zinc ion was 274.74 g, which was increased by 14.95% compared with the control rinsed with water. In addition, the maximum water-holding capacity was obtained (83.13%), accompanied by the minimum cooking loss percentage and transverse relaxation time (T23) (9.39% and 45.47 ms, respectively) and increased whiteness. Zinc ions led to cross-linking of myosin heavy chain into large aggregates, making the gel microstructure more compact and even.
