Abstract
Abstract The invention relates to a process for the modification of bran comprising forming a bran and water feed having a bran to water ratio of from 5.5:1 to 10:1 and extruding the feed in a counter-rotating twin screw extruder under high temperature and high shear conditions. The modified bran is more readily millable and when milled will possess a mouthfeel with an absence of grittiness and a greater functionality in a food product.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
A process for the modification of bran comprising: (a) combining bran with water to form a feed having a bran to water ratio of from 5.5:1 to 10:1; said bran containing from 10% to 25% starch on a dry weight basis, said starch either being naturally present in the said bran or admixed therewith; (b) introducing the feed into a counter-rotating twin screw extruder; (c) extruding the feed at a temperature of from 150° C. to 180° C.; and (d) developing a shear rate of from 500 to 2000 seconds -1 in said extruder through which the said feed is extruded.
Claim 2
Dependent Claim
101 words
A process for the modification of bran comprising: (a) combining bran with water to form a feed having a bran to water ratio of from 5.5:1 to 10:1; said bran containing from 10% to 25% starch on a dry weight basis, said starch either being naturally present in the said bran or admixed therewith; (b) introducing the feed into a counter-rotating twin screw extruder; (c) extruding the feed at a temperature of from 150° C. to 180° C.; and (d) developing a shear rate of from 500 to 2000 seconds -1 in said extruder through which the said feed is extruded.
