Kingdom Five unveils a new 'grown not processed' mycoprotein platform

Scottish food innovation company Kingdom Five has launched K5 Radical Protein, a new solid-state fermentation platform that grows whole-food mycoprotein using the edible filamentous fungus Neurospora.

The K5 Radical process produces naturally structured, high-protein, high-fibre foods with an authentic meat-like texture and flavour, without the heavy processing or added binders typically used in many meat alternatives.

Described as a 'grown not processed' innovation, the company’s approach enables the direct cultivation of mycoprotein into various formats such as sausages, fillets, nuggets and seafood-style products.

The platform is designed to provide food manufacturers with a sustainable, scalable solution that responds to growing consumer demand for nutritious and minimally processed meat-free foods.

“With K5 Radical, we can literally grow a meat-free sausage,” said Patrick Hickey, CEO and founder of Kingdom Five. “This technology lets us grow real food with texture and taste built in – which is not manufactured, but cultivated naturally.”
