Abstract
Abstract A method for treating a vegetable material containing protein is provided. In the method, an aqueous dispersion containing protein is prepared. The aqueous dispersion is then treated to provide a substrate that is relatively free from microbiological contamination. A viable culture of a particular yeast or mixture of yeasts is then added to the substrate. The yeast is selected so as to be capable of utilizing the carbohydrate material found in the vegetable protein source. Fermentation of the inoculated substrate is then effected under conditions which minimize production of alcohol.
