Abstract
A method for the production of microcapsules embedded with pharmaceuticals, peptides, proteins, enzymes and vaccines, which uses biodegradable solvents, and microcapsules free of toxic residual solvents is described. The microcapsules are obtained by spraying of a solution, suspension or water-in-oil dispersion of active materials and biodegradable polymers.
