Sustainable Nutrition: At Quorn, we produce our own unique protein called mycroprotein (Mycoprotein: Mycoprotein is a mold (member of the fungi family). There have been rare cases of allergic reactions to products that contain mycoprotein), which is a unique blend of protein and fiber. Producing mycroprotein (Mycoprotein: Mycoprotein is a mold (member of the fungi family). There have been rare cases of allergic reactions to products that contain mycoprotein.) uses less land and water than animal protein production, so it's better for the planet too!
