Founded in 1891

Rousselot was founded in France in 1891 by Edouard Rousselot. From our very beginning 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 available. With facilities, sales offices and on every continent, Rousselot is the world’s largest name in gelatin, a traditional ingredient used in the pharma, food and nutrition. In 2002, Rousselot became a part of VION Ingredients, a worldwide leader in the development and production of specialty ingredients from animal origin. Six years later, we strengthened our global position by acquiring Peptan, now the world’s leading collagen peptide brand.

A part of Darling Ingredients

In 2014, along with VION Ingredients, we became a part of Darling Ingredients, the world’s largest producer of sustainable natural ingredients from edible & inedible organic residuals and a respected global leader in repurposing. The roots of Darling Ingredients go back to 1882 and the founding of rendering company Ira C. Darling & Company in Chicago, Illinois, which over the years was to evolve into today’s Darling Ingredients. 

A global leader and innovator

With a legacy of over a century, Darling Ingredients has emerged as a global leader and innovator in the field of sustainable organic ingredients, providing quality products and services to processing industries around the world. Our critical and environmentally safe solutions for the removal and sustainable use of agricultural, industrial and food by-products help protect the food and feed chains, keep people and animals safe, and benefit people, businesses and the environment.

A legacy of service to global industries

Over the years, Darling Ingredients has expanded its business from traditional rendering operations to include a wide range of innovative residuals-to-resources services around the world. In January of 2014, Darling Ingredients expanded its operations to span five continents. We now offer a global portfolio of over 400 products and services for the food, feed, fuel and pharmaceutical industries that are used in businesses and homes around the world every day.
