摘要/Abstract

摘要： 以添加58%氯化钠、30%氯化钾、7%氯化钙、5%甘氨酸的低钠复合盐发酵香肠作为实验组，以100%氯化钠为对照组，通过测定理化指标、感官评价、电子舌味觉特征、游离氨基酸含量以及挥发性风味物质等探究低钠复合盐对发酵香肠品质的影响。结果表明：在香肠发酵成熟过程中，香肠pH值、水分含量呈显著下降趋势，钠含量显著增加。实验组pH值显著低于对照组，水分含量显著高于对照组，并且对产品的色泽和质构特性有一定改善作用，实验组在显著降低钠含量的同时，感官评价与对照组无明显差异。根据电子舌分析，实验组的鲜味、丰富度、苦味显著高于对照组。此外，实验组促进了游离氨基酸的释放，并对挥发性风味物质的产生没有负面影响。因此，实验组在减少42%食盐添加量的基础上，保证了发酵香肠良好感官和风味品质。

Abstract: The effect of partial replacement of sodium chloride by a low-sodium salt combination on the quality of fermented sausages was investigated by measuring physicochemical indexes, sensory evaluation, taste characteristics from electronic tongue, and the contents of free amino acids and volatile compounds. Two groups were designed, control group (100% sodium chloride), and experimental group (sodium chloride 58%, potassium chloride 30%, calcium chloride 7% and glycine 5%). The results showed that after 21 days of fermentation, the pH and moisture content of sausages decreased significantly, while the sodium content increased significantly. The pH and moisture content of the experimental group were significantly lower and higher than those of the control group, respectively. The low-sodium salt substitute improved the color and texture characteristics of the product without significantly changing the sensory quality. Electronic tongue analysis showed that the umami, richness and bitterness of the low-sodium salt group were significantly higher than those of the control group. In addition, the low-sodium salt substitute promoted the release of free amino acids while having no negative impact on the production of volatile compounds. Therefore, the experimental group reduced the NaCl content by 42% while maintaining good sensory and flavor quality.
