摘　　要：为确定改善带鱼鱼糜凝胶品质的最佳淀粉种类及其添加量,以凝胶强度、质构分析(TPA)值、白度、持水性和凝胶溶解度为指标,探究5种淀粉(小麦淀粉、马铃薯淀粉、木薯淀粉、交联淀粉和羟丙基淀粉)在不同添加量(0、5%、10%、15%和20%)下对带鱼鱼糜凝胶品质的影响。结果表明,不同种类淀粉以及添加量均对带鱼鱼糜凝胶品质有显著影响。当添加量超过15%后,淀粉的添加对带鱼鱼糜凝胶弹性和持水性影响不显著。5种淀粉中,木薯淀粉对带鱼鱼糜凝胶品质的改善效果最好,在鱼糜中添加15%木薯淀粉时,鱼糜凝胶强度、硬度、粘聚性、弹性、咀嚼性、白度值、失水率和凝胶溶解度分别为886.176 g·cm、4 879.56g、0.67、0.87、2 888.86、60.07、5.84%、49.47%。因此,添加15%的木薯淀粉能有效改善带鱼鱼糜凝胶品质。本试验结果为高品质鱼糜制品生产提供了科学依据。To determine the optimum kind and addition level of starch to imporve the gel quality of hairtail surimi,the effect of five different starches（ wheat starch,potato starch,cassava starch,cross-linked starch and hydropropylated starch） with different add quantity（ 0,5%,10%,15%,20%） on the gelation proportion of hairtail surimi was studied using the gel strength,TPA（ texture profile analysis） values,whiteness,water-holding ability,solubility of surimi gel as indexes. The results indicated that the type of starch and its add quantity had a significant influence on the gelation proportion of hairtail surimi. While add quantity of starch was more than 15%,the effect on the springiness and water-holding capacity was not significant. In the five kinds of starch,cassava starch had the best effect for improving the quality of hairtail surimi gel. With the addition of 15% cassava starch,the value of gel strength,hardness,cohesiveness,springiness,chewiness,whiteness,water-holding ability,solubility of surimi gel was 886. 176 g·cm,4879. 56 g,0. 67,0. 87,2 888. 86,60. 07,5. 84%,49. 47%,respectively. Therefore,adding 15% cassava starch could effectively improve the gel quality of hairtail surimi. The results can provide the theoretical basis for production of high-quality surimi products.
