Abstract: A process for making a high grade protein product, such as a mammalian feed product, using residue slurry from a cellulose fermentation and distillation process is provided. The residue slurry is compressed to remove much of the residual liquid. The compressed slurry is shaped, dried, leavened and granulated to provide the high grade protein product. Nutrients, flavorants, texturizers and other food product-enhancing ingredients may be added during the process. The granules of animal feed product can be packaged and stored in an inert or other stable environment for extended storage periods.
