A new innovative process has been developed to transform rapeseed press cake, traditionally an animal feed by-product, into a valuable protein source for human consumption, which could help meet the increasing global protein demand projected to double by 2050.

This approach emphasizes upgrading agricultural waste to create a more sustainable food system and reduce dependence on environmentally damaging livestock farming.

The research team used natural deep eutectic solvents and computer simulations to identify formulations that significantly boost protein yield from rapeseed press cake.

The findings, published in the journal Food Hydrocolloids, highlight a step toward more sustainable and resource-efficient food production.

While promising, further research is necessary to optimize the extraction process for commercial viability, focusing on improving yield and purity of the protein.

This discovery is particularly important because reducing reliance on livestock farming can significantly decrease greenhouse gas emissions, making it a promising environmentally friendly alternative.
