Summary for Patent: 8,945,642
Title:Nutritionally enhanced isolate from stabilized rice bran and method of production
Abstract: Provided is a nutritionally enhanced derivative (isolate) from Stabilized Rice Bran (SRB) with improved antioxidant, fat and protein levels enhancing both the nutritional and yield values over existing techniques. Also provided is an improved method that utilizes certain enzyme combinations under various time and temperature conditions for extracting these nutritionally enhanced isolates from SRB.

Assignee:
Application Number:12/882,202
Patent Claims:1. A nutritionally enhanced isolate of Stabilized Rice Bran prepared by a process comprising the steps of: providing a Stabilized Rice Bran material; adding water to the Stabilized Rice Bran material to produce an aqueous slurry including an insoluble fiber fraction; adding to the slurry a combination of enzymes consisting essentially of: a beta-glucanase enzyme; a thermotolerant protease enzyme mix derived from Carica papaya; and a thermostable alpha-amylase enzyme; heating the slurry to a first temperature in the range from 57.degree. C. to 97.degree. C. for 15 to 45 minuets; heating the slurry to a second temperature higher than the first temperature and in the range from 68.degree. C. to 108.degree. C. for 1 to 10 minutes; wherein the slurry has a pH in the range 6.0 to 7.0; isolating from the slurry fat and protein components that were released from the insoluble fiber fraction, and soluble dextrin that was converted from starch in the Stabilized Rice Bran material; wherein said stabilized rice bran comprises from 0.86 to 2.78 percent as-is protein, and from 0.93 to 2.5 percent as-is fat.

2. The nutritionally enhanced isolate of claim 1, wherein said protease comprises papain.

3. The nutritionally enhanced isolate of claim 1, wherein said protease comprises papain protease, glycyl endopeptidase, papaya protease, and chymopapain protease.

4. A method of creating a nutritionally enhanced isolate of Stabilized Rice Bran, comprising the steps of: providing a Stabilized Rice Bran material; adding water to the Stabilized Rice Bran material to produce an aqueous slurry including an insoluble fiber fraction; adding to the slurry a combination of enzymes consisting essentially of: a beta-glucanase enzyme; a thermotolerant protease enzyme mix derived from Carica papaya; and a thermostable alpha-amylase enzyme; heating the slurry to a first temperature in the range from 57.degree. C. to 97.degree. C. for 15 to 45 minuets; heating the slurry to a second temperature higher than the first temperature and in the range from 68.degree. C. to 108.degree. C. for 1 to 10 minuets; wherein the slurry has a pH in the range 6.0 to 7.0; isolating from the slurry fat and protein components that were released from the insoluble fiber fraction, and soluble dextrin that was converted from starch in the Stabilized Rice Bran material; wherein said stabilized rice bran comprises from 0.86 to 2.78 percent as-is protein, and from 0.93 to 2.5 percent as-is fat.

5. The method of claim 4, wherein said protease comprises papain.

6. The method of claim 4, wherein said protease comprises papain protease, glycyl endopeptidase, papaya protease, and chymopapain protease.
