摘要
本研究的目的是比较含胸腺酚的纳米结构脂质载体(NLC)和含亚硝酸盐(120 毫克/千克)的胸腺酚纳米乳液(NE)对香肠质量参数的影响。NLC和NE的液滴大小分别为140纳米和86.39纳米,封装效率分别为97%和94%。对香肠的研究结果表明,含有 NLC 和 NE 的所有样品的过氧化值、总挥发性碱基氮和 TBA 的升高幅度都最小,对大肠杆菌、产气杆菌、乳酸菌、嗜心性细菌、霉菌和酵母菌的生长以及总存活数的抑制作用最强,而且口感和感官属性良好,其中 NLC + 亚硝酸盐和 NE + 亚硝酸盐样品的效果最好。经过 4 周储存后,用亚硝酸盐、NLC + 亚硝酸盐和 NE + 亚硝酸盐处理的样品的 L* 和 a* 值相对较高。红色的增加与氧肌红蛋白水平的维持和高铁血红蛋白生成的减少有关。这项研究的结果表明,联合使用 NLC/NE(尤其是 NE)和 60 毫克/千克亚硝酸盐可显著提高香肠的氧化稳定性和色泽稳定性,并延缓香肠变质和异味的产生。
A comparative study between the performance of thymol-nanoemulsion and thymol-loaded nanostructured lipid carriers on the textural, microbial, and sensory characteristics of sausage
The objective of this research was to compare the function of thymol-loaded nanostructured lipid carriers (NLC) and a thymol-nanoemulsion (NE) with nitrite (120 mg/kg) on quality parameters of sausage. The droplet size of the NLC and NE was 140 and 86.39 nm with encapsulation efficiency of 97 and 94%, respectively. The results on sausage showed that all samples containing NLC and NE exhibited the lowest increase in peroxide value, total volatile base-nitrogen, and TBA with the highest inhibitory effect on the growth of E. coli, C. perfringens, lactic acid bacteria, psychrophilic bacteria, mold and yeast, and total viable counts as well as good texture and sensory attributes with the best results in the NLC + nitrite and NE + nitrite samples. The L* and a* values were relatively higher in the samples treated with nitrite, NLC + nitrite, and NE + nitrite after 4-week storage. This increase in redness was associated with the maintenance of oxymyoglobin levels and a decrease in metmyoglobin production. The results of this study indicated that the combined use of NLC/NE (particularly NE) with 60 mg/kg nitrite significantly improved the oxidative and color stability, and delayed the spoilage and off-flavor in sausage.
