The porous capslues were prepared by mechanical drilling, addition of effervescent to gelatin solution, or purging of inert gas into the gelatin solution. The porous capsules were then hardened by exposure to the cross-linking reagent, or by radiating under the UV, or microwave, or .gamma.-Ray. The usage of these porous gelatin capsules apart for pharmaceuticals extends to veterinary, cosmetic, and nutrient purposes. They are also utilized in the delivering of required beneficial agents to the chemical reactor, environment, and for agricultural purposes.
