A process to produce a protein concentrate from grain, specifically barley protein concentrate (BPC) through mechanical and biochemical intervention while producing multiple sugar streams as co-products. The resulting BPC preferably contains 54%-95% protein derived exclusively from the enzymatically processed barley and has a pH>5.0. The BPC may contain approximately 10% oil, less than 5% crude fiber, less than 1% residual glucose, and less than 0.5% phytic acid. The BPC contains no ethanol, organic acid, fermentation products, or microbial cells or cell mass. No fermentation occurs in the production of the BPC. The BPC has unique applications in formulations for aquaculture or livestock feed, and other pet food as well as for food formulations intended for human consumption. The sugar co-products, including glucose, have applications in industry and science and are particularly suitable for use as feedstocks for fermentation processes, livestock feeds, or biochemical conversion processes. |
