Abstract

Anticmicrobial effect of slightly acidic low concentration electrolyzed water (SlALcEW) and strong acidic electrolyzed water (StAEW) on fresh chicken breast meat was evaluated in this study. Meat samples each of 10 ± 0.2 g in weight and 2.5 × 2.5 cm 2 in size were experimentally inoculated withListeria monocytogenes(ATCC 19115) andSalmonella Typhimurium (ATCC 14028) and subjected to dipping treatment (22 ± 2 °C for 10 min) with SlALcEW and StAEW. Shelf-life study was conducted for inoculated and noninoculated meat samples treated with SlALcEW and StAEW at storage temperatures of 5, 15, and 25 °C. Dipping treatment with electrolyzed water significantly (P< 0.05) reduced the background and inoculated pathogens compared to untreated controls. The reduction of 1.5 to 2.3 log CFU/g was achieved by SlALcEW and StAEW against background flora, L. monocytogenesandSalmonella Typhimurium. There was no significant difference (P> 0.05) between the SlALcEW and StAEW treatments efficacy. Comparing treated samples to untreated controls showed that SlALcEW and StAEW treatments extended the shelf life of chicken meat at different temperatures with marginal changes of sensory quality. Although SlALcEW and StAEW treatments showed similar antimicrobial effects but SlALcEW was more beneficial in practical application for its semineutral pH and low chlorine content.
