Abstract

Extremely Low Frequency magnetic field (ELF-MF) is non-ionizing radiation with the process uses magnetic field through mrthods of ELF-MF can prevent food from contamination of Salmonella Typhimurium. The purpose of the research was to determine the intensity of the radiation dose and exposure time ELF magnetic fields appropriate to the prevalensi Salmonella Typhimurium in food sample (gado-gado seasoning). Sample ware trated using magnetic field with diferent intensities and times. The result showed that the pH measurement on sample no change significantly. Percentage of the deaths Salmonella Typhimurium were higher up to 36,37% by ELF magntic fields treatment with intensity 646,7 uT for 30 minutes, and can be contracted the length and diameter of the cell of Salmonella Typhimurium. It can be concluded that the radiation ELF-MF is able to inhibite growth of patogenic bacteria Salmonella Typhimurium .
