A complex, multi-stage process

The gelatins we produce at Rousselot Functional Ingredients are obtained by means of partial hydrolysis of collagen. Collagen is a raw material of natural origin, found mainly in pig skins, bovine hides and bovine bones. Collagen is naturally insoluble, whereas the gelatin resulting from the process of partial hydrolysis is soluble in warm water. This multi-stage process is complex and requires a high degree of control.

No chemical modification

We use two processes for manufacturing gelatin: alkaline or acid. The steps are described in the figure on this page. Every stage of the process occurs under strict hygienic conditions and throughout the entire manufacturing process no chemical modification takes place. By the end of the process, the gelatin appears in dry jelly noodles, which we then dry and grind into grains. The granular gelatin is then stored for further processing for different customers and applications.

Testing, control and traceability

The consistently high product quality for which our customers trust us is partially determined by our careful selection of raw materials and suppliers, and our emphasis on swift collection and transport. Of course, on top of that, all our raw materials undergo strict testing and control to ensure maximum quality, safety and traceability. At Rousselot Functional Ingredients we can trace the raw materials as well as the process conditions of every single batch.


We practice comprehensive quality management to comply with the highest international standards. All our production methods and processes are documented, and each finished product is subject to intensive testing before shipping.  Our certifications include ISO 9001 and HACCP for all our plants, and IFS, ISO 140001, FSSC 22000GMP, GMP+ and OHSAS 18001 for all plants and products to which these schemes apply.
