Darling Ingredients granted new patent for gelatin technology

Darling Ingredients announced that the U.S. Patent and Trademark Office has granted U.S. Patent No. 11795489B2 to its health brand Rousselot, securing Rousselot’s intellectual property rights for StabiCaps, a specialized gelatin that improves the formulation and stability of soft gel capsules to enhance the release of active ingredients, including medications. StabiCaps addresses crosslinking, a common challenge in the dissolution of soft gel capsules that results in slower or incomplete release of nutrients or pharmaceutical ingredients contained within the capsule. Crosslinking occurs when soft gel capsules are exposed to specific active compounds or poor storage conditions causing molecular bonds, that limit or prevent dissolution of the capsule, to form within the capsule shell. In May 2022, the company also received a patent from the European Patent Office for StabiCaps for all major European countries.
