Biopolymer functionalisation and characterisation
About this expertise
In short- Biopolymer functionalisation
- Biopolymer characterisation
- Industrial application
- Food and non-food applications
Biopolymers such as pectin, lignin and cellulose are used for many applications, from asphalt and construction material to paints, personal care products and packaging. However, each application requires biopolymers with a specific set of properties. We characterise and improve the functional properties of biopolymers to create functional materials for industrial use.
The challenge is to give biopolymers exactly the properties a product requires. Our work begins with detailed characterisation of a material’s composition and properties. Next, we develop technological pathways to give biopolymers the desired properties. These include chemical and chemical-catalytic processes and enzymatic routes. Another promising technology we apply is electrochemistry, with which we carry out efficient conversions into functionalised polymers or smaller molecules under mild conditions.
By bridging scientific insight with industrial needs, we create practical, scalable solutions that contribute to a more sustainable bioeconomy.
- Thanks to our clean label processing technology, we have demonstrated that starch can be customised for specific applications in food and non-food products.
- By using esterification, we can control the biodegradability and properties of cellulose.
- With enzymatic functionalisation we are able to give pectin tailor-made properties which can be used in, for example, applications like automatic dishwashing or leather products.
- We have developed several non-food applications for protein fractions in leather, glue and coating applications.
- We have developed patented technologies to apply lignin as bitumen substitute in bio asphalt.

What if we could use the power of plants to create a very strong adhesive? Lignin is a natural binder that occurs in woody materials, like trees, grasses and straw. By carefully researching the properties and characteristics of the materials, as well as ways to process it, Wageningen Food & Biobased Research has been able to adjust it in such a way that it can replace many fossil-based adhesives. This material is currently used in for instance high performance panels for furniture or in bitumen and asphalt.
