Abstract

In the present work, fresh beef was treated with 3 g/L sodium lactate, while fresh beef without treatment served as negative control. Based on the comprehensive analyses of pH, total volatile basic nitrogen (TVB-N), colour, and microbial quality, the acceptable shelf life of chilled beef treated with sodium lactate was six days, while the control was acceptable for three days. Sodium lactate usage was conducive to hygiene levels improvement. Lactobacillus spp. and Weissella spp. sharply displaced the Ralstoni spp. with high potential spoilage, and became the predominant bacteria. Moreover, the proliferation of Serratia spp. was completely controlled by sodium lactate treatment. Sodium lactate usage exhibited a better pH stability and outstanding colour stability together with antibacterial efficacy. Furthermore, we suggested the mechanistic insights on colour stability and antibacterial efficacy of sodium lactate due to its roles in the regeneration of reduced nicotinamide adenine dinucleotide (NADH) together with pH regulation.
乳酸钠通过色泽稳定性和抗菌活性提高冷藏牛肉的新鲜度
在本研究中,新鲜牛肉经 3 克/升乳酸钠处理,而未经处理的新鲜牛肉作为阴性对照。根据对 pH 值、总挥发性碱氮(TVB-N)、色泽和微生物质量的综合分析,经乳酸钠处理的冷藏牛肉的可接受货架期为 6 天,而对照组的可接受货架期为 3 天。乳酸钠的使用有利于提高卫生水平。乳酸菌属和魏氏菌属大幅取代了具有高腐败潜力的拉尔斯顿菌属,成为主要细菌。此外,乳酸钠处理完全控制了沙雷氏菌的增殖。乳酸钠具有更好的 pH 稳定性和出色的颜色稳定性,同时还具有抗菌功效。此外,我们还提出了乳酸钠在还原型烟酰胺腺嘌呤二核苷酸(NADH)的再生和 pH 值调节中的作用,从而对乳酸钠的颜色稳定性和抗菌效果产生了机理上的影响。
