Abstract
A process for the recovery and purification of waste gelatin, especially from the manufacture of soft gelatin capsules includes the steps of effecting dissolution of the gelatin and other water-soluble components of the waste in a solvent such as deionized water such that a gelatin-containing solution dispersed within the remaining components of said waste is formed, permitting the dispersion to settle into an upper oil phase and a lower solvent based gelatin-containing solution phase, separating the lower phase from the upper phase, optionally hot filtering the lower phase to remove traces of the remaining components of the upper phase, and diafiltering the lower phase to remove the active ingredients, glycerin, and other water-soluble components and to provide a recycled gelatin solution.
