Abstract：
Slightly acidic electrolyzed water (SAEW) is a safe and effective disinfectant, but its sterilizing efficiency is compromised by organic matter on the egg surface. Electrolyzed reduced water (ERW) is a harmless cleaner with a decontamination effect on a variety of surfaces and can be used to remove organic matter. This study assesses the effectiveness of a combination of ERW and SAEW in eliminating Salmonella and manure mixture from egg surfaces, as well as its impact on egg quality during storage. The results show that ERW (74.14%) was more effective than deionized water (DW, 64.69%) and SAEW (70.20%) (P < 0.05) in removing manure from egg surfaces. The damage to the cuticle of eggshell treated with ERW for 28 s was similar to that of DW (P > 0.05) and less than that of SAEW (P < 0.05). Spraying ERW for 10 s followed by SAEW for 18 s (ERW + SAEW) completely removed Salmonella from the egg surface, with no bacteria detected in the residual wash solution. Additionally, ERW + SAEW demonstrated superior preservation of egg quality during storage at 25℃ than the control and ERW single treatment (P < 0.05). Moreover, ERW + SAEW resulted in less weight loss compared to SAEW single treatment (P < 0.05). In conclusion, the sequential use of ERW and SAEW appears to be a promising approach for sterilizing eggs. It not only removes organic matter and Salmonella from the egg surface but also improves the preservation quality of the egg at 25 ℃.
摘要：
微酸性电解水(SAEW)是一种安全有效的消毒剂,但是它的杀菌效率受到鸡蛋表面有机物的影响。电解还原水（ERW）是一种无害的清洁剂，对多种表面具有去污作用，可用于去除有机物。这项研究评估了ERW和SAEW组合在消除鸡蛋表面沙门氏菌和粪肥混合物中的有效性。以及它在储存过程中对鸡蛋质量的影响。结果表明，ERW(74.14%)比去离子水(DW，64.69％）和SAEW（70.20％）（P<0.05）从鸡蛋表面去除粪便。ERW处理28s对蛋壳角质层的损伤与DW相似（P>0.05），小于SAEW（P<0.05）。喷洒ERW10s，然后用SAEW18s（ERWSAEW）从鸡蛋表面完全去除沙门氏菌，在残留的洗涤溶液中没有检测到细菌。此外,ERW+SAEW在25℃贮藏期间的蛋品质保存优于对照和ERW单一处理(P<0.05)。此外，与SAEW单次治疗相比,ERW+SAEW导致更少的体重减轻(P<0.05)。总之,依次使用ERW和SAEW似乎是对鸡蛋进行灭菌的一种有希望的方法.它不仅可以去除鸡蛋表面的有机物和沙门氏菌，而且可以提高鸡蛋在25℃下的保存质量。
