Gelatin-based compositions and a method for the generation of stabilized foams therefrom
 A method for the generation of gelatin-based stabilized foams by passing a stream of air or other gas through a composition of the gelatin, an anionic surface-active agent and a water soluble ferrous salt. The resulting foams have a relatively long life term.
