摘要
为研究氯化钾替代一定量的食盐和TG酶对低盐巴沙鱼肠品质的影响,试验在鱼肉100 g、盐5 g的基础上,用氯化钾替代50％、40％、30％、20％、0％的食盐添加量(质量分数),在每个替代量下又分别添加了 0％、0.4％、0.6％、0.8％的TG酶,探究对低盐巴沙鱼肠品质的影响.结果表明,在试验条件范围内,一定的氯化钾替代食盐量和TG酶对鱼肠的得率、色差和质构等指标有显著影响.当氯化钾替代食盐量为0％～50％、各组TG酶添加量为0％～0.8％时,其水分含量呈现先降低后升高的趋势.当氯化钾代替食盐量为30％、40％、50％时,添加0.4％～0.8％的TG酶也能显著提高低盐鱼肠的硬度、弹性、咀嚼性等指标(P＜0.05).当氯化钾替代量为30％、TG酶添加量为0.4％时,鱼肠的硬度比空白组提高2.14倍,咀嚼性提高3.54倍,胶黏性提高2.16倍,同时优于其他替代组.根据低盐鱼肠相关检测指标的主成分分析结果,得出添加TG酶对低盐鱼肠品质的综合评价模型,为鱼糜制品和水产行业提供了参考数据.
Abstract
To study the effects of replacing some amount of salt with potassium chloride and transglutaminase(TGase)on the quality of low-salt Pangasius bocourti sausages,in this test,on the basis of 100 g fish and 5 g salt,potassium chloride is used to replace 50％,40％,30％,20％,0％of salt addition amount(mass fraction),and at each replacement amount,0％,0.4％,0.6％,0.8％TGase is added to investigate the effect on the quality of low-salt Pangasius bocourti sausages.The results show that under the test conditions,a certain amount of potassium chloride as a substitute for salt and TGase has significant effects on improving the yield,color difference and texture of fish sausages.When the amount of potassium chloride replacing salt is 0％～50％,and the TGase addition amount in each group is 0％～8％,the water content firstly decreases and then increases.When the amount of potassium chloride replacing salt is 30％,40％,50％,adding 0.4％～0.8％TGase can also improve the hardness,elasticity,chewiness and other indexes significantly(P＜0.05).When the replacement amount of potassium chloride is 30％and the addition amount of TGase is 0.4％,the hardness of the fish sausages increases by 2.14 times,the chewiness increases by 3.54 times,and the viscosity increases by 2.16 times that of the blank group,which are better than those of the other replacement groups.Based on the results of principal component analysis of low-salt fish sausages,the comprehensive evaluation model of the addition of TGase on the quality of low-salt fish sausages is obtained,which has provided reference data for surimi products and aquatic industry.
