High-protein plant extract is obtained by comminuting young green plant material, pressing the material to force liquid therefrom, and coagulating and separating the true protein fraction of this liquid. The remaining liquid, which can contain toxic substances, is inoculated with a yeast capable of utilizing nitrogen sources and subjected to aerobic fermentation until the nitrogen sources are substantially exhausted and the toxicants greatly reduced. The yeast is then concentrated, either by separation or by evaporation, and combined with the coagulated true protein thereby to obtain an extract which is detoxicated. |
