What is Corn Gluten Meal?

Corn gluten meal is a byproduct of the corn milling process. It is a yellowish powder that is rich in protein and is commonly used as a feed ingredient for livestock and poultry. However, it also has various other applications, including as a natural herbicide and as a source of plant-based protein for humans.

The Production Process

The production of corn gluten meal starts with the milling of corn kernels. The kernels are ground into a fine powder, and then the starch and germ are separated from the protein-rich endosperm. The endosperm is further processed to remove any remaining impurities, resulting in a pure and concentrated form of corn gluten meal.

Benefits and Uses

Corn gluten meal has several benefits and uses. Firstly, it is a valuable source of protein for livestock and poultry. It contains around 60% protein, making it a highly nutritious feed ingredient. Additionally, it is rich in amino acids, which are essential for the growth and development of animals.

Furthermore, corn gluten meal can be used as a natural herbicide. It contains a compound called corn gluten, which inhibits the germination of weed seeds. When applied to lawns or gardens, it prevents the growth of unwanted plants, making it an effective and environmentally friendly alternative to chemical herbicides.

Benefits for Humans

While corn gluten meal is primarily used as a feed ingredient for animals, it also has benefits for humans. It is a valuable source of plant-based protein, making it an excellent choice for vegetarians and vegans. Additionally, it is gluten-free, making it suitable for individuals with gluten sensitivities or celiac disease.

Moreover, corn gluten meal is rich in vitamins and minerals, including vitamin B-12, iron, and zinc. These nutrients are essential for maintaining good health and can contribute to a balanced diet.

Environmental Impact

One of the significant advantages of corn gluten meal is its positive environmental impact. As a natural herbicide, it helps reduce the reliance on chemical weed killers, which can be harmful to the environment and human health. By using corn gluten meal, individuals can contribute to sustainable and eco-friendly gardening practices.

Additionally, corn gluten meal is a byproduct of the corn milling process, which means it utilizes a waste product that would otherwise be discarded. This reduces waste and promotes a more efficient use of resources.


In conclusion, corn gluten meal is a versatile and valuable product with various benefits and uses. It is a rich source of protein for livestock and poultry, a natural herbicide for weed control, and a plant-based protein option for humans. Its positive environmental impact and efficient use of resources make it an excellent choice for sustainable and eco-friendly practices. Whether used in animal feed or as a natural weed killer, corn gluten meal offers numerous advantages and contributes to a healthier and more sustainable future.
