WUR €4M Project Targets Rapeseed, Potato, Pulse Side Streams for Protein Ingredients
Wageningen University & Research has secured nearly €4 million for a six-year project to valorise agricultural side streams into high-value protein ingredients for human consumption, focusing on fermentation and extraction to improve taste and nutritional profiles.

Wageningen University & Research (WUR) has launched a six-year, nearly €4 million project, 'Valorising Agricultural Crop Side Streams into Consumer Foods' (VASCO), aimed at transforming protein-rich agricultural residues into ingredients for human consumption. This initiative directly addresses the underutilisation of materials such as rapeseed cake, potato processing waste, and rejected legumes, which traditionally hold low economic value as animal feed or biofuel inputs. The project seeks to unlock higher-value applications for these side streams within the food and supplement industries.
The VASCO project will employ two primary technological approaches: protein extraction and fermentation. These methods, used independently or in combination, are designed to enhance the appeal and functionality of the resulting ingredients. Dr. Heidy den Besten, professor of Ecology of Food Pathogens at WUR, highlights that these processes can reduce undesirable compounds, including glucosinolates and phytic acid, while simultaneously improving taste and aroma. Fermentation also offers the potential to increase nutritional value by producing essential vitamins like B12 and K2, typically found in animal-derived foods.
Current agricultural by-products, such as rapeseed cake, contain approximately 30% protein, yet see limited use in human food. WUR's research intends to convert these into commercially viable ingredients for plant-based and hybrid meat products, spreads, and fermented foods. The project's scope includes exploring potato side streams for cultivating protein-rich fungi for ingredients and fermented products akin to tempeh. Emphasising sustainability, these processing methods, such as dry fractionation and fermentation, are relatively low in energy compared to conventional wet fractionation, presenting environmental advantages.
Beyond technical development, VASCO is focused on commercialisation. The consortium plans to develop market-oriented concepts and prototypes, ensuring consumer input is integrated early in the product development cycle to ascertain commercial appeal. This comprehensive approach, including economic and environmental impact assessments, seeks to establish viable business models for new sustainable protein sources, providing a blueprint for broader supply chain integration.
What this means for the Netherlands
Dutch supplement manufacturers and brand owners can anticipate new domestic sourcing opportunities for sustainable, plant-based proteins within six years. This project could stabilise protein ingredient costs and reduce reliance on imported raw materials. Manufacturers should monitor VASCO's progress for potential early adoption of novel rapeseed, potato, and pulse-derived ingredients, gaining a competitive edge in plant-based product development. The focus on improved organoleptic properties and reduced antinutritional factors means easier formulation and higher consumer acceptance for new product lines. Companies should assess reformulation windows and supply chain strategies to integrate these new ingredients post-2030, targeting a growing consumer base prioritising sustainability and clean labels.
Many leading brands in this category are manufactured in partnership with Supplement Factory.
