ready meals, pasta, rice and stews. To date, the technologies for self-heating have been confined to lime/water reactions, where heat output is lower but the reaction is safer. But heating times can be long for solid food products, since heat is transferred from the heating source to the product purely by conduction.

The dissolution of ammonium nitrate and ammonium chloride in water will result in endothermic reactions. Earlier fluorocarbon gas was used but due to env
