Abstract
Abstract A composition of matter comprising an insoluble dietary fiber material coated with hemicellulose is provided. In preferred embodiments, the insoluble dietary fiber material and hemicellulose are derived from grain hulls. The weight ratio of insoluble dietary fiber material to hemicellulose is generally greater than about 1:1. Also provided is a method of coating an insoluble dietary fiber material with a hemicellulose. Preferred embodiments employ a fluidized bed technique to obtain the coating of hemicellulose.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
82 words
A method of preparing a soluble/insoluble dietary fiber supplement from corn bran comprising: (a) removing from a first portion of corn bran at least a portion of a digestible component thereof to concentrate the dietary fiber content thereof and yield an insoluble fiber; (b) extracting hemicellulose from a second portion of corn bran, (c) coating the insoluble fiber with the hemicellulose using an aqueous medium, and (d) removing said aqueous medium from said coating to deposit said hemicellulose upon said insoluble fiber.
Claim 2
Independent Claim
82 words
A method of preparing a soluble/insoluble dietary fiber supplement from corn bran comprising: (a) removing from a first portion of corn bran at least a portion of a digestible component thereof to concentrate the dietary fiber content thereof and yield an insoluble fiber; (b) extracting hemicellulose from a second portion of corn bran, (c) coating the insoluble fiber with the hemicellulose using an aqueous medium, and (d) removing said aqueous medium from said coating to deposit said hemicellulose upon said insoluble fiber.
Claim 3
Dependent Claim
21 words
A method of claim 1 wherein said insoluble fiber is suspended in a fluidized bed during said coating and said removing.
Claim 4
Dependent Claim
20 words
A method of claim 1 wherein said insoluble fiber is sprayed with a solution of hemicellulose in said aqueous medium.
Claim 5
Dependent Claim
27 words
A method of claim 1 further comprising dry mixing said insoluble fiber and hemicellulose and then mixing water as the aqueous medium with the resulting dry mixture.
Claim 6
Dependent Claim
20 words
A method of claim 4 wherein said dry mixing is accomplished in a fluidized bed into which water is introduced.
Claim 7
Dependent Claim
50 words
A method of claim 1 wherein said coating is accomplished by precipitating said hemicellulose from said aqueous medium onto said insoluble fiber and said removing is accomplished by physically isolating the resulting coated insoluble fiber from the resulting aqueous phase and then drying the resulting isolated and coated insoluble fiber.
Claim 8
Dependent Claim
26 words
A method of claim 1 wherein the weight ratio of insoluble fiber to hemicellulose deposited on said insoluble fiber ranges from about 1:1 to about 50:1.
Claim 9
Independent Claim
65 words
A method of coating an insoluble dietary fiber with hemicellulose comprising; (a) dry mixing said insoluble dietary fiber and hemicellulose and then mixing water as an aqueous solvent with the resulting dry mixture to coat said insoluble dietary fiber with a solution of hemicellulose in aqueous solvent, and (b) removing said aqueous solvent from said mixture to deposit said hemicellulose upon said insoluble dietary fiber.
Claim 10
Independent Claim
65 words
A method of coating an insoluble dietary fiber with hemicellulose comprising; (a) dry mixing said insoluble dietary fiber and hemicellulose and then mixing water as an aqueous solvent with the resulting dry mixture to coat said insoluble dietary fiber with a solution of hemicellulose in aqueous solvent, and (b) removing said aqueous solvent from said mixture to deposit said hemicellulose upon said insoluble dietary fiber.
Claim 11
Dependent Claim
20 words
A method of claim 8 wherein said dry mixing is accomplished in a fluidized bed into which water is introduced.
Claim 12
Dependent Claim
38 words
A method of claim 8 wherein said insoluble dietary fiber and said hemicellulose are derived from corn grain hulls and the weight ratio of said insoluble dietary fiber to said hemicellulose ranges from about 1:1 to about 50:1.
Claim 13
Independent Claim
91 words
A method of coating an insoluble dietary fiber with hemicellulose comprising: (a) coating insoluble dietary fiber with a solution of hemicellulose in an aqueous solvent, and (b) removing said aqueous solvent from said coating to deposit said hemicellulose upon said insoluble dietary fiber, wherein said coating is accomplished by precipitating said hemicellulose from said aqueous solution onto said insoluble dietary fiber and said removing is accomplished by physically isolating the resulting coated insoluble dietary fiber from the resulting aqueous phase and then drying the resulting isolated and coated insoluble dietary fiber.
Claim 14
Independent Claim
91 words
A method of coating an insoluble dietary fiber with hemicellulose comprising: (a) coating insoluble dietary fiber with a solution of hemicellulose in an aqueous solvent, and (b) removing said aqueous solvent from said coating to deposit said hemicellulose upon said insoluble dietary fiber, wherein said coating is accomplished by precipitating said hemicellulose from said aqueous solution onto said insoluble dietary fiber and said removing is accomplished by physically isolating the resulting coated insoluble dietary fiber from the resulting aqueous phase and then drying the resulting isolated and coated insoluble dietary fiber.
Claim 15
Dependent Claim
38 words
A method of claim 11 wherein said insoluble dietary fiber and said hemicellulose are derived from corn grain hulls and the weight ratio of said insoluble dietary fiber to said hemicellulose ranges from about 1:1 to about 50:1.
