Abstract

Extremely Low Frequency Magnetic Field (ELF-MF) is non-ionizing and non-termal radiation. The previous research result was proven that prevalence death of Salmonella typhimurium in the fisiology liquid that has positive correlation with exposure intensity, but without exposure duration. The exposure of ELF 646.7 μT magnetic field during 30 minutes gives higher Salmonella death impact rather than 60 minutes and 90 minutes exposure. The objective of this research was to determine dose effectiveness of ELF magnetic field exposure in Gado-Gado fresh food as sterilization alternative method from Salmonella typhimurium. The sample in this research was Gado-Gado (containing of seasoning and vegetables) which was gotten from the street vendors around Jember University campus. The dose of ELF magnetic field exposure that be tested was on 646.7 μT with exposure during 30 minutes. The dose effectiveness of Extremely Low Frequency (ELF) magnetic field with 646.7 μT intensity during 30 minutes was proven can decrease Salmonella typhimurium population in Gado-Gado by inhibition effectiveness was shown by the destruction percentage in Gado-Gado seasoning was 56% and in Gado-Gado vegetables was 17%. According to the result of this research, it could be concluded that ELF magnetic field radiation has potency as the sterilization alternative method of fresh food which was cheap and safe from Salmonella typhimurium.

利用极低频(ELF)磁场对加多-加多地区鼠伤寒沙门菌进行替代杀菌研究
极低频磁场(ELF-MF)是一种非电离和非热辐射。以往的研究结果证明,培养液中鼠伤寒沙门菌的流行死亡与暴露强度呈正相关,而与暴露时间无关。与暴露60分钟和90分钟相比,暴露30分钟的ELF 646.7 μT磁场对沙门氏菌的死亡影响更高。本研究的目的是确定极低频磁场暴露在加多加多新鲜食品中作为鼠伤寒沙门菌灭菌替代方法的剂量有效性。本研究的样本为Gado-Gado(含调味料和蔬菜),来自Jember大学校园周围的街头小贩。所测极低频磁场暴露剂量为646.7 μT,暴露时间为30分钟。以646.7 μT强度的极低频(ELF)磁场照射30 min,对加多加多地区鼠伤寒沙门菌的抑制率为56%,对加多加多蔬菜的抑制率为17%。本研究结果表明,极低频磁场辐射作为一种廉价、安全的新鲜食品防鼠伤寒沙门菌灭菌替代方法是有潜力的。
