摘  要：
该文旨在采用自行设计的磁场杀菌装置 ,研究磁场非热杀菌技术。以啤酒酵母、大肠杆菌为对象菌 ,探求磁通密度、磁场极性转换时间等因素对对象菌的致死率影响规律 ,研究啤酒酵母磁场非热杀菌动力学。试验结果表明 :磁通密度对啤酒酵母、大肠杆菌杀菌率有一定影响 ,对啤酒酵母、大肠杆菌致死效果最好的磁通密度分别为 1.5 T,1T。初菌浓度、磁通密度对大肠杆菌致死率有显著影响 ,当磁通密度为 1T的磁场作用 8h,磁场对大肠杆菌致死率为 78%。对象菌受磁致死的动力学方程的表达与化学一级反应方程相仿。

摘  要：
The main aim of this paper is to study on technology of magnetic filed non-thermal sterilization using a self-designed generator of magnetic field. The Saccharomyces Cerevisiae and Escherichia Coli as the object microorganism, the effect of the magnetic flux density, the time of magnetic field pole conversion on the destruction rate of microorganism was probed. The kinetics of the magnetic field sterilization to Saccharomyces Cerevisiae was investigated. The results showed that 1) the magnetic flux density had a certain influence on the destruction rate of the object microorganism. The magnetic flux densities which had the greatest effect on the destruction rate of Saccharomyces Cerevisiae and Escherichia Coli were 1.5 T, 1 T respectively. 2) The original concentration of Escherichia Coli and the magnetic flux density influence the destruction rate at a very significant level. The greatest destruction rate of Escherichia Coli was 78% under 8 hours magnetic flied (1 T) treatment. 3) The kinetics equation of this sterilization for the object microorganism could be described as a first-order chemical reaction.
