Abstract: In this paper, aluminium-magnesium-iron (Al-Mg-Fe) based water activated ration heater for ready foods was prepared by using a simple method. The effects of the difference molar ratio of precursors on the thermal properties of water activated ration heater had been investigated. According to FLIR study, (Al-Mg-Fe) based water activated ration heater synthesized by using (Al-Mg-Fe) mixture and NaCl reaches the peak temperature 91.5 º C and the highest average temperature of 75.75 ºC within 12 minutes. According to the XRD result, aluminium-magnesium-iron based water activated ration heater synthesized by using 1:0.75 mass ratio of (Al-Mg –Fe) mixture and NaCl has the complete reaction. These mass ratio was also get the best results in the performance of heating test continue again.

Keywords: Water activated ration heater, aluminium-magnesium-iron powder, FLIR study, XRD, NaCl
