Why does self-heating rice heat itself?

Self-heating box lunch is actually the result of the reaction between the water bag in the box and the heating agent packaged in non-woven fabric. Once the plastic strip is pulled apart, the water bag will burst. At this time, the heating agent will react with water, so that the heating agent will radiate heat evenly and generate heat as high as 120℃.

After 5-8 minutes, when the temperature of the food reaches 55℃-70℃, you can eat delicious food. After the heating agent reacts with water, the steam produced is non-toxic and harmless.
