Research and application of electrochemical activation solution Anolit to disinfect chicken carcass on the slaughter line industry

Abstract

This study was undertaken to investigate the efficacy of anolyte mixed water (AMW) in killing pathogen bacteria on chicken carcasses under in laboratory  testing and industrial processing conditions. In laboratory testing, chicken  carcasses  contaminated  with bacteria solutions were subjected to treatment with anolyte (free chlorine 300 mg/l). The results indicated that Salmonella, S. aureus,  Campylobacter reducing  (1.38 log₁₀ to 1.90 log₁₀ cfu/g) were better than E.coli,  C.  perfringens and  B.  cereus reducing  (0.43  log₁₀ to  0.76  log₁₀ cfu/g)  after  30 s treatment. In industrial processing conditions, immersion treatments of chicken carcasses with AMW (free chlorine 50 mg/l) were significantly moreeffective than using water. The treatment of  chickens  carcasses  by  spraying  AMW  (free  chlorine  50  mg/l)  significantly  reduced  the bacteria population of  E.coli and Coliforms by 2.19 log₁₀ and 2.12 log₁₀ cfu/cm² ,respectively. The results also suggested that chicken carcasses may be prevented the cross-contamination in the chiller tank by using AMW (free chlorine 50 mg/l).
