玉米籽粒经食品工业生产淀粉或酿酒工业提纯后的副产品，其蛋白质营养成分丰富，并具有特殊的味道和色泽，可用作饲料使用。
玉米蛋白粉也叫玉米麸质粉，是玉米粒经湿磨工艺制得玉米粗淀粉乳，经过水解、分离、浓缩、发酵烘干制成,其蛋白质含量20%~ 70 %，是一种极具开发潜力的蛋白质原料。主要由玉米蛋白组成，含有少量的淀粉和纤维。
玉米蛋白粉蛋白含量高，含氨基酸丰富，在豆饼、鱼粉短缺的饲料市场中可用来替代豆饼、鱼粉等蛋白饲料。玉米蛋白粉蛋白质营养成分丰富，不含有毒有害物质，不需进行再处理，可直接用作蛋白原料，是饲用价值较高的饲料原料。
Corn gluten meal, also known as corn gluten meal, is a protein raw material with great potential for development. It is made by wet grinding corn kernels to produce corn coarse starch milk, which is then hydrolyzed, separated, concentrated, fermented, and dried. Its protein content ranges from 20% to 70%. It is mainly composed of corn protein and contains a small amount of starch and fiber.
Corn protein powder has a high protein content and is rich in amino acids. It can be used as a substitute for protein feed such as soybean cake and fish meal in the feed market where soybean cake and fish meal are scarce. Corn protein powder is rich in protein nutrients and does not contain toxic or harmful substances. It does not require further processing and can be directly used as a protein raw material. It is a feed material with high feeding value.
