摘　　要：目的:为有效利用带鱼鱼糜加工副产物,确定以其为原料制得的酶解物螯合钙的最佳螯合工艺。方法:在单因素试验基础上,采用Box-Behnken响应面分析法,探讨酶解物与氯化钙的螯合工艺条件。结果:优化的螯合工艺为:酶解物与氯化钙质量比6.4∶1,料液比1∶50 g/m L,温度30℃,时间21 min,pH 7.0,在此工艺条件下螯合率和螯合物得率分别为83.41%和13.49%,与预测值83.56%和13.61%吻合。结论:所确定的螯合工艺反应条件温和,反应速度快,酶解物与钙的螯合率和螯合物得率都较高,为钙螯合物的制备以及带鱼鱼糜加工副产物的高值化利用提供依据。In order to more efficient use of hairtail surimi processing by-products, investigation were carried out to optimize the preparation of hydrolysate chelating calcium from that. On the basis of results of the single factor experiment, the Box-Behnken central composite design and response surface method were adopted to explore the optimum chelating conditions of hydrolysate and calcium. The optimal chelate conditions were determined as： weight ratio of hydrolysate to calcium chloride 6.4∶1, ratio of solid to liquid 1∶50, temperature 30 ℃, time 21 min, pH 7.0. Under such conditions, chelate rate and yield could reach 83.41% and 13.49% respectively, which were well matched with predicted value of 83.56% and 13.61%. This optimal chelate conditions could obtain higher chelate rate and yield, which established a basis for the application of hydrolysate chelating calcium and more economic benefit of hairtail surimi processing enterprise.
