Abstract

1. The effects of electrolysed water (acidic or slightly acidic) on microbial load and physicochemical properties of chicken carcases were determined. Chicken carcases treated with chemical decontamination solution (chlorine dioxide) on the slaughter line were used as the control group (C). The other two experimental groups consisted of groups A - treated with acidic electrolysed water and B - treated with slightly acidic electrolysed water.2. On d 1 and 7 post slaughter, samples were evaluated for physicochemical and microbiological characteristics. The pH, oxidation reduction potential (ORP) and available chlorine concentration (ACC) values of the solutions used in the application were determined.3. During storage, lipid oxidation remained stable in the samples treated with slightly acidic electrolysed water (p < 0.05). In addition, the application of acidic electrolysed water significantly (p < 0.05) decreased b* (yellowness) colour in the samples. Carcases in the A group had the lowest counts of total coliform bacteria, total mesophilic aerobic bacteria and S. aureus on d 1 (p < 0.05). Campylobacter counts in samples from group B significantly (p < 0.05) decreased during the storage period. The lowest E. coli count was detected in group A on both d 1 and 7 (p < 0.05). The reduction in Salmonella spp. counts during storage was similar in all groups.4. The results suggested that electrolysed water applications may be appropriate as an alternative to the chlorine dioxide solution used on the slaughter line in chicken slaughterhouses.

利用酸性和微酸性电解水作为潜在的非热食品消毒剂控制家禽业微生物种群。

1. 研究了电解水（酸性或微酸性）对鸡胴体微生物负荷和理化性质的影响。以屠宰线上用化学去污液（二氧化氯）处理过的鸡胴体为对照组(C)，其余2个试验组为酸性电解水处理A组和微酸性电解水处理B组。在屠宰后的第1天和第7天，对样品进行理化和微生物学特性评估。测定了应用中所用溶液的pH、氧化还原电位（ORP）和有效氯浓度（ACC）值。在储存过程中，经微酸性电解水处理的样品中脂质氧化保持稳定（p p b*（黄色））。A组胴体中大肠菌群总数、嗜中温需氧细菌总数和金黄色葡萄球菌总数均低于B组（p < 0.05），弯曲杆菌总数显著低于B组（p < 0.05）。A组在第1天和第7天均检测到大肠杆菌计数(p)，贮藏期间各组沙门氏菌计数基本一致。结果表明，在鸡屠宰场的屠宰线上，电解水可以作为二氧化氯溶液的替代品。

期刊介绍： From its first volume in 1960, British Poultry Science has been a leading international journal for poultry scientists and advisers to the poultry industry throughout the world. Over 60% of the independently refereed papers published originate outside the UK. Most typically they report the results of biological studies with an experimental approach which either make an original contribution to fundamental science or are of obvious application to the industry. Subjects which are covered include: anatomy, embryology, biochemistry, biophysics, physiology, reproduction and genetics, behaviour, microbiology, endocrinology, nutrition, environmental science, food science, feeding stuffs and feeding, management and housing welfare, breeding, hatching, poultry meat and egg yields and quality.Papers that adopt a modelling approach or describe the scientific background to new equipment or apparatus directly relevant to the industry are also published. The journal also features rapid publication of Short Communications. Summaries of papers presented at the Spring Meeting of the UK Branch of the WPSA are published in British Poultry Abstracts .
