大蒜液杀灭副溶血弧菌效果及影响因素的试验研究

目的观察大蒜液对副溶血弧菌的杀灭效果及其影响因素。方法应用悬液定量杀菌试验观察大蒜液对副溶血弧菌的杀灭作用及温度、pH、有机物对杀菌效果的影响。结果大蒜液对副溶血弧菌作用30 min,杀灭率为100%;大蒜液室温存放时间<4 h对其杀菌率无影响(P>0.05)、存放>8 h杀菌率明显下降;杀菌作用随温度升高、pH降低而增强,因有机物存在而明显减弱。结论大蒜液可杀灭悬液中副溶血弧菌,杀菌效果受大蒜液存放时间、悬液温度、pH、有机物存在的影响。

Germicidal Efficacy of Garlic Solution and Its Influencing Factors on Vibrio parahaemolyticus: An Experimental Research

OBJECTIVE To observe germicidal efficacy of garlic solution on Vibrio parahaemolyticus and its(influencing) factors.METHODS The quantitative solution germicidal test was performed to observe the germicidal efficacy of garlic solution on V.parahaemolyticus,as well as to observe the influences of temperature,pH and(organic)(substances).RESULTS The killing rate of V.parahaemolyticus in suspension exposed to garlic solution for 30 min was 100%;no(influence) on its germicidal rate(P>0.05) after storing at room temperature less than 4 hours.Its germicidal rate decreased obviously after storing at room temperature more than 8 hours.The(germicidal) efficacy was enhanced with the up of temperature and down of pH,and sharply down with the existence of organic substances.(CONCLUSIONS) Garlic solution can kill the V.parahaemolyticus.Its storing time as well as the temperature,pH,and organic substances can influence the germicidal efficacy.
