摘 要: 细菌污染是食品生产的重要危害,而高强度磁场对细菌的生长有一定的抑制作用,可望用于细菌对食品的危害控制。通过研究静态磁场强度和磁场处理时间对细菌存活率的影响,探讨了静态磁场对细菌的作用规律,并对磁场处理前后的细菌进行了DNA图谱分析。研究结果可为磁场处理技术在食品工业上的应用提供初步理论分析和实验依据。 Bacteria are regarded as the main hazard in food industry, and bacteria can be affected by a static magnetic field (SMF) with high intensity. So the SMF would be useful for controlling the bacteria' s hazard to food. The effect of magnetic induction, treatment time on bacteria, and the survival probability of bacteria under SMF were studied for investigating their action regularity, and the DNA fingerprint of strains after magnetic treatment was compared with that of control. The research results would lay the basis of SMF application in food industry on theory and practice.
