Founded in 1891

Rousselot was founded in France in 1891 by Edouard Rousselot. From our beginnings as a family-owned business, our commitment to high-quality, safe products, enabled us to develop an understanding of gelatin and related ingredients – both operationally and technologically – that is unparalleled throughout the world. Today, our company offers the widest range of gelatins and collagens available.

In 2002, Rousselot became a part of VION Ingredients, a worldwide leader in the development and production of specialty ingredients of animal origins. Six years later, we strengthened our global position by acquiring Peptan, now the world’s leading collagen peptide brand. In 2014, Rousselot became a part of Darling Ingredients.

In 2018, we expanded our portfolio and entered the market for (bio)medical applications with a new range of high-purity gelatins and collagens called X-Pure®

In 2019, Rousselot announced the reorganization of its brands and products into three new strategic segments: Rousselot Health & Nutrition, Rousselot Biomedical and Rousselot Functional Ingredients.

And on March 2023, Darling Ingredients Inc. completed the acquisition of Gelnex, a leading global producer of gelatin and collagen products.
