Development of novel functional proteins and bioactive ingredients from rapeseed, olive, tomato and citrus fruit side streams for applications in food, cosmetics, pet food and adhesives


Pro-Enrich project will demonstrate a new business model for extracting high-value components from agricultural side streams, demonstrating technically and commercially feasibility for both small and large-scale bio-processing units.

The Pro-Enrich project will develop a flexible biorefinery approach able to processing a range of agricultural residues from rapeseed meal, olives, tomatoes and citrus fruit industries. This will help fulfil the growing global demand for alternative sources of protein and phenolic product streams.

Pro-Enrich take the process of fractionising biomass to a new level, identifying proteins, polyphenols, dietary fibres and pigments for use as food ingredients, pet food, cosmetics and adhesives.



The specific objectives of the Pro-Enrich project are to:

  • Determine the components with the highest market potential from the four residue streams being investigated, as evaluated by the project industrial end user partners;
  • Undertake a range of bio-refining processes that yield high quantities of high-purity functional proteins and bioactive components;
  • Develop the biorefinery processes in pilot scale, advancing the best businesses cases to demonstration scale.
  • Apply components isolated from the bio-refining into key market areas and demonstrate their fitness for purpose;
  • Undertake a system analysis to make these processes technically and economically attractive;
  • Undertake sustainability assessments of process alternatives to ensure that any new product ranges developed provide environmental benefits.
  • Carry out a feasibility assessment of the Pro-Enrich business model.

As well as its contribution to the overall BBI-JU goals and Key Performance Indicator, the Pro-Enrich project aims to have the following impacts:

  • Create two new cross-sector interconnections in bio-based economy clusters;
  • Introduce pressed olive pomace, olive mill waste water, rapeseed meal press cake and fruit and vegetables processing residues as valuable bio-refining resources;
  • Develop protocols for producing four different ingredients with a purity levels enabling their use in foods, pet foods, cosmetics and adhesives;
  • Define how to adapt modern bio-refineries to seasonal residues within the same processing unit, reducing downtime and increasing return on investment
  • Apply a circular and cascading biorefinery approach to feedstocks that delivers a more environmentally and economically sustainable process, including a reduction in carbon footprint over existing processes of at least 10 percent.

Upcycling food waste into new proteins and ingredients
Food Manufacture, 21 August 2020
The creation of highly-valuable plant-based ingredients by BBI JU-funded project Pro-Enrich is featured in the specialised portal. The project uses of by-products and waste from agriculture and food producers to boost the circularity of resources.
