A pilot-scale process for preparing high-protein, low fiber (〈l%) products from 150-lb batches of wheat millrun and shorts using a wet alkaline method is described. The protein concentrates contained 60–70% protein when starch was removed prior to protein precipitation and 25–26% protein with the starch present. Yields of the protein concentrates ranged from 4.1 to 33.6% of the raw material starting weight (dry basis), depending on the processing conditions employed. Yield could be increased by re-extracting the pressed residue. Water requirements for extraction were lowered from 750 to 263 lb by extracting the raw material with the deproteinized mother liquor from the previous lot.
