An exothermic, hydratable fuel mixture for a self-heating food container comprises particles of a base such as lime and an acid such as oxalic acid. When water is added to the mixture, exothermic heat is generated by hydration of the lime and neutralization reaction between the lime and the acid. Mixtures of bases and mixtures of acids can be used to optimize the heating characteristics of the fuel mixture.

A self-heating, food container comprising in combination: a first closed container for receiving the food to be heated; a second container surrounding the first container forming an annular chamber divided by a water impermeable film into an upper compartment and a lower compartment; and a body of fuel consisting essentially of a mixture of particles of a solid anhydrous base that exothermically reacts with water and particles of a solid anhydrous acid that exothermically reacts with said base to produce a non-toxic, non-hazardous salt, received in the lower compartment; and a body of water received in the upper compartment, whereby on rupture of said film, the base exothermically reacts with the water and the acid to produce said salt.
