What Is Corn Gluten: A Natural Weed Control?
What Is Corn Gluten?
Corn gluten is a protein derived from the endosperm of corn.
It is mainly composed of zein and glutelin and is a byproduct of corn processing.
Corn gluten is commonly used as animal feed, with a crude protein content of about 65%.
Additionally, it can be used as an herbicide and acts as a fertilizer due to its high nitrogen content.
However, it should not be applied in areas where it can directly wash into watersheds due to nitrogen runoff.
The effectiveness of corn gluten as a preemergent herbicide is still inconclusive, and it is not regulated as an herbicide in the US.
Additionally, corn gluten is used in the manufacture of hydrolyzed vegetable protein, a food flavoring.

Did You Know?
1. Corn gluten is not actually gluten in the traditional sense. Despite its name, corn gluten is a natural protein found in corn, which is gluten-free and safe for people with gluten intolerances.
2. Corn gluten can be used as a natural weed killer. When used in a lawn or garden, it acts as a pre-emergent herbicide, inhibiting the growth of certain types of weeds without harming other plants.
3. Corn gluten is a valuable source of animal feed. Due to its high protein content, corn gluten meal is often used as an ingredient in livestock and poultry diets, providing essential nutrients and serving as an alternative to other protein sources.
4. Corn gluten can be used as a meal replacer for humans. In some vegetarian and vegan recipes, corn gluten can be blended with other ingredients to create a meat-like texture and increase the protein content.
5. The production of corn gluten has a positive environmental impact. Corn gluten is a by-product of the corn milling process, which reduces waste and maximizes the use of corn crops. Additionally, as a natural fertilizer, corn gluten helps promote healthier soil and reduces the need for chemical fertilizers.
Introduction To Corn Gluten Meal As A Byproduct
Corn gluten meal is a protein derived from the endosperm of corn, which is the starchy part inside the corn kernel. It is a byproduct of the corn processing industry, primarily produced through the wet-milling process. During this process, the germ, which contains oil, and the endosperm are separated. The endosperm is then dried and ground into a fine meal, resulting in corn gluten meal.
The composition of corn gluten meal is mainly composed of two proteins, zein and glutelin. Zein accounts for the majority of the protein content, while glutelin provides additional nutritional value. This protein-rich meal has various applications, including as animal feed, herbicide, fertilizer, and even in food production.
Corn Gluten Meal As Animal Feed With High Protein Content
One of the primary uses for corn gluten meal is as animal feed. It contains approximately 65% crude protein, making it a valuable source of nutrition for livestock. The high protein content makes it an excellent feed option for animals that require significant amounts of protein, such as poultry and swine.
In addition to protein, corn gluten meal also serves as a source of energy and pigments for livestock. It provides a balanced nutritional profile that supports the growth and overall health of animals. Moreover, corn gluten meal has proven to be highly digestible, making it a popular ingredient in pet foods as well.
Utilization Of Corn Gluten Meal As Herbicide And Fertilizer
Apart from its uses as animal feed, corn gluten meal can also be utilized as an herbicide and fertilizer. Its high nitrogen content makes it an effective fertilizer, providing plants with the necessary nutrients to promote growth. This natural fertilizer is especially beneficial in organic farming practices, where synthetic chemical fertilizers may be avoided.
Moreover, corn gluten meal has shown potential as a preemergent herbicide. When applied to an area before the germination of weeds, it can inhibit their growth by preventing the development of their root systems. However, the effectiveness of corn gluten meal as a herbicide is still inconclusive, and further research is needed to determine its optimal application.
Precautions For The Application Of Corn Gluten Meal
While corn gluten meal can be beneficial for weed control and fertilization, it is essential to take precautions during its application. One crucial consideration is to avoid applying it in areas where it can directly wash into watersheds. The nitrogen content in corn gluten meal can lead to nitrogen runoff, which can have detrimental effects on water bodies and aquatic ecosystems.
Additionally, it is important to note that corn gluten meal is not regulated as an herbicide in the United States. Therefore, its efficacy and safety may not be guaranteed compared to regulated herbicides. It is always recommended to follow proper application guidelines and consult with experts for optimal usage.
Other Applications Of Corn Gluten In Food Production
Aside from animal feed and weed control, corn gluten has additional applications in the food industry. It is used in the manufacture of hydrolyzed vegetable protein, which is a popular food flavoring. Hydrolyzed vegetable protein provides a savory taste, often referred to as umami, and is commonly used in processed foods, soups, sauces, and snacks.
Corn gluten meal should not be confused with corn gluten feed, which has a lower protein content. Corn gluten feed is a mixture of bran, steep liquor, and maize germ oil, often used as livestock feed as well. It is important to distinguish between these two products based on their nutritional composition and intended applications.
corn gluten meal is a versatile byproduct of corn processing. It serves as a valuable source of protein for animal feed, contributes to weed control as a potential herbicide, and provides essential nutrients as a fertilizer. However, precautions must be taken to prevent detrimental environmental effects, and its application as an herbicide should be further researched. Additionally, corn gluten finds uses in the food industry, particularly in the production of flavorings.

Frequently Asked Questions
What is corn gluten made of?
Corn gluten is made up of the protein component obtained from the wet milling process of corn. During this process, the corn kernel is broken down into starch, oil, protein, and bran. The protein is separated and collected to create corn gluten feed. This protein-rich byproduct contains essential nutrients such as minerals, vitamins, and energy sources, making it a valuable ingredient in various food products and animal feed.
Is corn gluten different than wheat gluten?
While both corn gluten and wheat gluten are derived from the endosperm of the respective plants, they differ in composition and properties. Corn gluten, although commonly referred to as a “gluten,” is not a true gluten like wheat gluten. This is because it lacks the protein structure, specifically glutenin and gliadin, that gives wheat gluten its elastic properties. Therefore, corn gluten is not suitable for baking and does not have the same binding capabilities as wheat gluten.
Furthermore, there are notable differences in the protein profiles of corn gluten and wheat gluten. Wheat gluten is known for its high content of gluten proteins, which are responsible for its elasticity. In contrast, corn gluten contains different proteins, such as zein, which do not provide the same properties as glutenin and gliadin. These distinctions make corn gluten a viable alternative for certain applications, such as an organic weed control, but it cannot be used as a replacement for wheat gluten in baking or other culinary purposes.
What is another name for corn gluten?
Another name for corn gluten is maize gluten meal. This product is derived from the separation of starch and primarily consists of gluten. With a high protein content of about 60%, maize gluten meal is distinct from corn gluten feed, which contains approximately 20% protein. It is also referred to as corn gluten or maize gluten in various contexts.
How to make corn gluten?
To make corn gluten, corn is first soaked in water mixed with sulfur dioxide and then ground to separate the germ from the endosperm to extract oil. The next step involves separating the starch and proteins from the corn fiber through screenings. Finally, the starch and proteins left are centrifuged to separate the starch from the corn gluten meal, resulting in the production of corn gluten. This process efficiently extracts gluten from corn and can be used in various applications, including as a feed ingredient for animals or as an organic herbicide for weed control.
