초록

주요 식중독균인 E. coli O157:H7, L monocytogenes, S. aureus, S. Typhimurium과 S. Enteritidis를 주어진 이산화염소수 농도에서 시간별로 처리한 inactivation data를 first-order kinetic model과 Weibull model을 이용하여 kinetic parameter를 비교, 분석하였다. 그 결과 Weibull model이 first-order kinetic mode

Inactivation kinetic data of Escherichia coli O157:H7, Listeria monocytogenes, Staphylococcus aureus, Salmonella Typhimurium, and Salmonella Enteritidis via treatment with aqueous chlorine dioxide treatment at a specific concentration were evaluated using the first-order kinetic and Weibull models. The Weibull model showed a better fit with the kinetic data than the first-order kinetic model. The survival curves after the aqueous chlorine dioxide treatment showed values(time required to reduce microbial populations by 90%) of 2.49 min for E. coli O157:H7 at 5 ppm, 1.47 min for L. monocytogenes at 5 ppm, 0.94 min for S. aureus at 5 ppm, 0.87 min for S. Typhimurium at 1 ppm, and 0.08 min for S. Enteritidis at 1 ppm, according to the Weibull model.
