响应面法优化罗非鱼复合下脚料鱼糜凝胶品质的研究

摘要

采用响应面法对罗非鱼下脚料复合鱼糜进行凝胶品质优化.以凝胶强度为主要评价指标,先进行单因素筛选出对复合下脚料鱼糜凝胶影响因素大的原料,然后进行响应面分析.响应面分析结果:复合鱼糜用量180 g、TG酶0.78 g、乙酰化二淀粉磷酸酯20 g、冰水40 g、卡拉胶0.4 g时,该鱼糜的凝胶强度预测值达到674.74 g/cm,实际凝胶强度达到661.53 g/cm,模型预测精度为98%.%The gel quality optimization of tilapia byproduct surimi is adopted based on response surface method.Use gel strength as the main index, the single factor is used to screen out the raw material with large influence on compound minced tilapia scraps and the response surface analysis is adopted.Response surface analysis results show that composite surimi dosage of 180 g, TG enzyme of 0.78 g, acetylated distarch phosphate of 20 g, ice water of 40 g, carrageenan of 0.4 g, the predicted value of gel strength reaches 674.74 g/cm, the actual value of gel strength reaches 661.53 g/cm, the prediction accuracy of the model is 98%.
