Corn fiber hulls as a food additive or animal feed

A food additive or an animal feed produced by a method for making said food additive or animal feed comprising the steps of:

• obtaining a corn fiber slurry having a moisture content from about 30 weight percent to about 50 weight percent solids;
• thermochemically processing said corn fiber slurry to produce a hydrolyzed corn fiber slurry;
• dewatering said hydrolyzed corn fiber slurry to achieve a first residual corn fiber, said first residual corn fiber having a moisture content from about 30 to about 80 weight percent solids;
• washing said first residual corn fiber;
• dewatering said washed, hydrolyzed corn fiber slurry to achieve a second residual corn fiber, said second residual corn fiber having a moisture content from about 30 to about 80 weight percent solids;
• extracting said second residual corn fiber with an extractant and separating at least one phytosterol from said second residual corn fiber to achieve an extracted corn fiber;
• collecting said extracted corn fiber;
• and
• making an animal feed or a food additive comprising said extracted corn fiber.
