中文摘要: 为解决卤牛肉在实际生产过程中肉汁损失、口感下滑等劣变问题,研究不同添加量(0%、1.0%、2.0%、3.0%)的可得然胶对卤牛肉品质特性的影响。低场核磁(low-field nuclear magnetic resonance,LF-NMR)分析表明,可得然胶使卤牛肉中不易流动水含量显著提高(P<0.05),自由水含量降低,使得蒸煮得率显著提高(P<0.05),当添加量为3.0%时,蒸煮得率增加33.43%。质构分析显示,可得然胶明显降低卤牛肉的硬度、咀嚼性及剪切力,当添加量达到2.0%时,剪切力降低29.31%。可得然胶添加量从0%增加到2.0%时,卤牛肉切面逐渐顺滑、呈色均匀且具有诱人光泽,切面亮度值提高12.69%,总体可接受性评分最高。但当添加量继续增加至3.0%时,卤牛肉切面呈现出大片的类似胶状的成分,感官品质降低。此外,可得然胶添加可有效抑制冷藏过程中卤牛肉的脂肪氧化,且2.0%添加量时效果最佳。
Abstract:In view of the gravy loss and taste deterioration occurred during the production of spiced beef,the impacts of curdlan added at different levels(0%,1.0%,2.0%,and 3.0%)on the quality characteristics of the product were studied.The low-field nuclear magnetic resonance(LF-NMR)analysis revealed an increase in immovable water content(P<0.05)and a decrease in free water content after the addition of curdlan,which resulted in a notable increase in the cooking yield(P<0.05).At an addition level of 3.0%,curdlan increased the cooking yield by 33.43%.The results of the texture analysis indicated that the addition of curdlan reduced the hardness,chewability,and shear force of the spiced beef(P<0.05).At an addition level of 2.0%,curdlan reduced the shear force by 29.31%.The spiced beef produced with the addition of curdlan at 0%-2.0% presented a smooth and uniformly colored section with an attractive luster(evidenced by a 12.69% increase in the brightness value)and the highest score of overall acceptability.However,increasing the concentration of curdlan to 3.0% led to the formation of large jellylike components on the section and a significant decrease in the sensory quality.In addition,curdlan can inhibit the fat oxidation of spiced beef during the refrigeration process,demonstrating the best inhibitory effect at the addition level of 2.0%.
