淀粉和鱼糜品质对鱼糜凝胶性质的影响

Effects of starch and surimi quality on the gel properties of surimi gels

  • 摘要: 本文探讨了糯玉米淀粉、马铃薯淀粉和变性淀粉对不同品质鱼糜凝胶形成能力的影响。结果发现,添加糯玉米淀粉后鱼糜制品的破断强度从266.57 g下降至175.00 g,硬度、胶黏性、咀嚼性也发生下降,而添加马铃薯淀粉可以使鱼糜制品的破断强度和部分质构得到显著提高。另一方面,冻融变性鱼糜制备的产品其破断强度、硬度、胶黏性、咀嚼性出现下降,添加马铃薯淀粉能提高其产品的凝胶性质。不论鱼糜是否发生冻融变性,添加三种淀粉后鱼糜制品的持水力和蒸煮时的吸水率都显著提高,但鱼糜制品的色泽变差。根据SDS-PAGE结果,可以发现添加糯玉米淀粉、马铃薯淀粉和变性淀粉都不会影响鱼糜蛋白之间的交联。SEM结果表明添加马铃薯淀粉可以使鱼糜凝胶网络结构变得更加致密有序,从而增强鱼糜制品的凝胶强度。以上结果表明,马铃薯淀粉比糯玉米淀粉和变性淀粉更适合作为鱼糜制品的辅料和添加剂。 

     

    Abstract: Effects of waxy corn starch,potato starch and modified starch on the properties of surimi gels from different quality surimi were investigated.With adding corn starch,the breaking force of surimi gels was decreased from 266.57 g to 175.00 g,and the hardness,gumminess and chewiness were also decreased. But the breaking force and some texture properties of surimi gels were increased remarkably after adding potato starch. The breaking force,hardness,gumminess and chewiness of surimi gels were higher than those from freeze-thawing surimi. However,the gel properties of surimi gel from freeze-thawing surimi were improved by adding potato starch. Regardless of freeze-thawing surimi or not,the water holding capacity and cooking absorption of surimi gels were increased by adding starches,while the color was deteriorated.Based on the SDS-PAGE of surimi gels,it was found that the interaction between surimi proteins was not affected by waxy corn starch,potato starch and modified starch.The result of SEM showed the network of surimi gel became compact and orderly by adding potato starch,thus improving the gel properties. From above results,it led the conclusion that potato starch was more suitable for the excipients and food additives of surimi products than waxy corn starch and modified starch.
