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.
Claims6
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.degree. C. to 180.degree. C.;
- and
- (d) developing a shear rate of from 500 to 2000 seconds.sup.-1 in said extruder through which the said feed is extruded.
