Abstract:
A process for treating rice bran, preferably defatted rice bran, to produce a high value protein product and a cellulosic residue both from rice bran. The high value protein product is useful as a protein supplement or feed for livestock and poultry and the cellulosic residue has value as a feedstock for a thermochemical process unit for the production of a biofuel. The rice bran is subjected protein hydrolysis and a resulting liquid stream containing hydrolyzed proteins is sent through a two membrane filtration stages, the first being a microfiltration and the second being a nanofiltration stage.

Claim (Index 1):
A process for producing a protein product suitable for human consumption and a cellulosic product suitable as a feedstock for thermochemical processing from rice bran containing a starch component and a protein component, which process comprises:\n a) introducing into a hydrolysis reactor, with constant stirring, rice bran an effective amount of water, so that a slurry is formed having a ratio of water to rice bran, by weight, of from about 8:1 to about 11:1; b) heating said slurry to a temperature from about 30\u00b0 C. to about 70\u00b0 C.; c) providing that the pH of the slurry be in the range from about 7 to about 10.5; d) introducing into said hydrolysis reactor an effective amount of alkaline protease enzyme; e) maintaining hydrolyzing condition, including temperatures from about 30\u00b0 C. to about 70\u00b0 C. and a pH of about 7 to 10.5, for an effective amount of time to allow the degree of hydrolysis of proteins to reach between 1 to 10; f) raising the temperature an effective amount to result in deactivating the protease enzyme; g) conducting the slurry resulting from step f) above to a liquid/solids separation stage resulting in a wet-solids fraction comprised of cellulosic residue material, and a liquid fraction comprised of water, protein, oils, sugars, fiber and ash; h) conducting said aqueous fraction to a membrane microfiltration stage containing a membrane capable of performing a separation in the 20 to 500 kDa size range thereby resulting in a retentate comprised of cellulosic residue material and a permeate comprised of water and hydrolyzed protein products; i) conducting said permeate to a membrane nanofiltration stage containing a membrane capable of performing a separation in the 500 to 1500 Daltons size range, thereby resulting in a retentate comprised of hydrolyzed protein products, and a permeate comprised of an aqueous solution of water-soluble constituents, including monosaccharides, resulting from the above process steps; j) spray drying said retentate resulting in a spray dried hydrolyzed protein product; and k) drying said wet-solids fraction resulting from step g) above to produce a dried cellulosic residue product.
