Mycoprotein is a biomass of the fungi cells of Fusarium venenatum with a reduced content of RNA. It consists of about 50 % of protein, 12 % of lipids, 12 % of sugars, and 25 % of dietary fibre. The amino acid content in mycoprotein is comparable with the amino acid content in meat, egg, soy, and wheat proteins. The mycoprotein processed by texturization can be used as a meat substitute.
