Abstract
Abstract A process for producing a high total dietary corn fiber. Undried corn fiber obtained from the corn wet-milling process is separated by means of a sifter to give a coarse fiber fraction of enhanced total dietary fiber content. The coarse fiber fraction is then passed through a roller mill to give a product of even higher total dietary fiber content.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
131 words
A process for producing an improved corn fiber product of high dietary fiber content from the undried mixed fiber obtained from a corn wet-milling process which comprises: (a) passing the undried mixed fiber obtained from the corn wet-milling process through a sifter fitted with a screen; (b) separating a coarse fiber fraction which does not pass through the screen in the sifter; (c) passing the coarse fiber fraction through a roller mill fitted with corrugated rolls operating at different speeds; (d) passing the coarse fiber fraction exiting from the roller mill of Step (c) through a sifter fitted with a screen; and (e) separating a coarse fiber fraction which does not pass through the screen in the sifter in Step (d), thereby, obtaining a corn fiber of high dietary fiber content.
Claim 2
Dependent Claim
131 words
A process for producing an improved corn fiber product of high dietary fiber content from the undried mixed fiber obtained from a corn wet-milling process which comprises: (a) passing the undried mixed fiber obtained from the corn wet-milling process through a sifter fitted with a screen; (b) separating a coarse fiber fraction which does not pass through the screen in the sifter; (c) passing the coarse fiber fraction through a roller mill fitted with corrugated rolls operating at different speeds; (d) passing the coarse fiber fraction exiting from the roller mill of Step (c) through a sifter fitted with a screen; and (e) separating a coarse fiber fraction which does not pass through the screen in the sifter in Step (d), thereby, obtaining a corn fiber of high dietary fiber content.
Claim 3
Dependent Claim
23 words
The process of claim 1 wherein the undried mixed fiber has a moisture content of from about 40% to about 60% by weight.
Claim 4
Dependent Claim
28 words
The process of claim 1 wherein the sifter used in Steps (a) and (d) is fitted with a screen having openings from about 2.0 to about 4.0 mm.
Claim 5
Dependent Claim
40 words
The process of claim 1 wherein the roller mill used in Step (c) is fitted with rolls operating at a roll speed differential of about 1.1:1 to 2:1 and roll gap of from about 0.10 mm to about 1.5 mm.
Claim 6
Dependent Claim
15 words
The process of claim 1 wherein the roller mill is a multiple roller milling machine.
Claim 7
Dependent Claim
91 words
A process for producing an improved corn fiber product of high dietary fiber content from the undried mixed fiber obtained from a corn wet-milling process which comprises: (a) passing the undried mixed fiber obtained from the corn wet-milling process through a sifter fitted with a screen; (b) separating a coarse fiber fraction which does not pass through the screen in the sifter; and (c) drying said coarse fiber fraction, thereby, obtaining a corn fiber of higher dietary fiber content than that of the mixed fiber obtained from the corn wet-milling process.
Claim 8
Dependent Claim
91 words
A process for producing an improved corn fiber product of high dietary fiber content from the undried mixed fiber obtained from a corn wet-milling process which comprises: (a) passing the undried mixed fiber obtained from the corn wet-milling process through a sifter fitted with a screen; (b) separating a coarse fiber fraction which does not pass through the screen in the sifter; and (c) drying said coarse fiber fraction, thereby, obtaining a corn fiber of higher dietary fiber content than that of the mixed fiber obtained from the corn wet-milling process.
Claim 9
Dependent Claim
23 words
The process of claim 6 wherein the undried mixed fiber has a moisture content of from about 40% to about 60% by weight.
Claim 10
Dependent Claim
28 words
The process of claim 6 wherein the sifter used in Steps (a) and (d) is fitted with a screen having openings from about 2.0 to about 4.0 mm.
