In this paper, anolyte is considered as a possible disinfectant for inhibiting the growth of bacteria in meat (beef cuts and minced pork). Meat cuts were contaminated with two concentrations of and Typhimurium, as these are the most common meat pathogens that are closely regulated by the EU, and treated with two different concentrations of anolyte: 20% for beef cuts and 18% for minced pork. Then, the total viable count (TVC), count and Typhimurium count were determined. In meat cuts and minced pork, anolyte was able to reduce TVC, Typhimurium and counts effectively, significantly decreasing and Typhimurium counts after spraying and throughout 29 days of incubation at 0-4 °C. TVC was reduced after spraying and for 10 days of incubation but later increased to be the same as before spraying with anolyte. Anolyte was effective when spraying beef cuts with a 20% solution for 60 s against pathogenic bacteria and spp. and also when using it at a concentration of 18% from the minced meat mass. Initially, anolyte significantly decreased TVC, however during the storage period (10-29 days) TVC increased but remained significantly lower compared to control. Anolyte was effective in reducing and Typhimurium counts throughout the study, and after 29 days of incubation, these bacteria could not be detected in the samples treated with anolyte.
在本文中，阳极电解液被视为一种可能的消毒剂，用于抑制肉类（牛肉块和猪肉末）中细菌的生长。将肉块用两种浓度的鼠伤寒沙门氏菌污染，因为这些是欧盟严格管控的最常见的肉类病原体，并用两种不同浓度的阳极电解液处理：牛肉块用20%的，猪肉末用18%的。然后，测定了总活菌数（TVC）、大肠杆菌计数和鼠伤寒沙门氏菌计数。在牛肉块和猪肉末中，阳极电解液能够有效降低TVC、大肠杆菌和鼠伤寒沙门氏菌计数，在喷雾后以及在0-4℃下培养29天的整个过程中，显著降低大肠杆菌和鼠伤寒沙门氏菌计数。喷雾后以及培养10天时TVC降低，但之后又升高至与用阳极电解液喷雾前相同。用20%的溶液对牛肉块喷雾60秒时，阳极电解液对病原菌大肠杆菌和金黄色葡萄球菌有效，从肉末质量计以18%的浓度使用时也有效。最初，阳极电解液显著降低TVC，然而在储存期（10-29天）TVC升高，但与对照相比仍显著较低。在整个研究过程中，阳极电解液在降低大肠杆菌和鼠伤寒沙门氏菌计数方面有效，培养29天后，在用阳极电解液处理的样品中未检测到这些细菌。
