A method of recovering water-insoluble and water-soluble protein fractions from protein-polysaccharide complexes such as wheat gluten involves subjecting a complex of this type to an enzyme treatment in the presence of a liquid so as to decompose at least a portion of the polysaccharide content of the complex and dissolve at least a portion of the protein content of the complex thereby obtaining a suspension of protein solids in the solution formed by the liquid. The liquid used is preferably water. The suspension is separated into a solids fraction and a liquid fraction by centrifugation of filtration. The solids fraction and liquid fraction are then treated separately from one another to thereby obtain a water-insoluble protein fraction and a water-soluble protein fraction. The treatment of the solids fraction may involve washing of the same followed by drying. The treatment of the liquid fraction may involve desalination, subsequent concentration by evaporation and drying of the concentrate obtained by virtue of the evaporation. |
