ABSTRACT:
Trub obtained from the wort kettle of a brewing system is rich in protein and thus can be used in human foods. The trub is processed to yield a trub flour by extraction with an azeotropic mixture of isopropanol and water, and drying to remove the solvent in a roller drum drier, the latter yielding the trub flour in dry flake form.
