Aspects of the present invention provide a corn protein isolate, comprising at least about 85 wt % corn protein on a dry basis; an 'a*' color value ranging from about −0.5 and 1.5, and a “b” color value ranging from about 10 and 25; and less than about 1.5% oil on a dry basis. Further aspects include methods of making the same.

Corn protein isolate and methods of manufacturing same

Disclosed herein is a method of maintaining corn protein yield during extraction and managing stickiness and viscosity comprising obtaining a corn material having a corn protein content and washing the corn material to remove non-protein components with an ethanol-water solvent comprising at least 85 wt % ethanol to obtain a corn protein isolate, wherein the loss of corn protein content during extraction is less than 10% of total corn protein.

Corn protein retention during extraction

Described herein is a method of maintaining corn protein yield during extraction, comprising obtaining a corn gluten material, washing the corn gluten material to remove non-protein components with an ethanol-water solvent comprising at least 85 wt % ethanol to obtain a corn protein concentrate product, wherein the loss of corn protein content during extraction is less than 25% of total corn protein.

Described herein is a corn protein product comprising greater than about 20% corn protein on a dry weight basis and a free sulfite concentration of less than 150 ppm on an as-is basis. Also disclosed herein is a method to obtain this corn protein product including the steps of providing a protein-rich stream derived from a wet corn milling operation, wherein the protein-rich stream comprises greater than 20% corn protein on a dry weight basis, and treating the protein-rich stream with an oxidant, preferably hydrogen peroxide.

Corn protein product having decreased free sulfite levels and method for manufacturing same

Methods and apparatus for separating and removing aflatoxin-contaminated corn from batches of corn by a floating process, thus producing a distinguishable floating mat of contaminated corn and a separate submerged bed of uncontaminated and less contaminated corn. The methods of this disclosure include removing the floating contaminated corn mat by a vacuum mechanism or by liquid flow. The methods reduce the aflatoxin level in the submerged corn bed as much as 80% from the initial aflatoxin level, while removing no more than 15% from the batch of corn.
