Description
Summary:The growing global population and rising protein demand are straining freshwater resources. Fusarium venenatum (Fv) mycoprotein offers a sustainable protein alternative, with environmental efficiency and potential health benefits. However, its low iron content remains a concern, especially for vegetarians and vegans. This study introduces a sustainable approach, employing seawater as a fermentation medium for Fv production. Our analysis reveals that mycoprotein derived from SEA Fv exhibits elevated levels of sodium and calcium, with a notably high iron content (2.2 mg/100 g wet weight). The sodium content, while 3.31 times higher than in non-seawater fermentation, remains within recommended daily intake parameters. No plasticizers or heavy metals were detected in the SEA Fv cell body, minimizing long-term toxicity risks from seawater use. A unique metabolite, dihydroorotic acid, was identified from an in-house library of 774 metabolites, serving as an internal biomarker for seawater-based production methods. An acute safety study condensing 600 g of SEA Fv to simulate high mycoprotein digestion showed no effects on key physical behaviors or major organs, including the heart and lungs. This positions the product as a viable protein alternative with enhanced iron content, highlighting seawater-based fermentation as a sustainable method for future food production and industry progress.
