Uses of Field Corn in Human Consumption
Field corn is a versatile crop that plays a crucial role in many food products we enjoy every day, including cornmeal and sweet corn. Let’s explore some of its most popular human consumption uses.
Cornmeal and Flour Production
Field corn is a versatile crop that can be converted into various forms of flour and meal, making it an essential ingredient in many baked goods. The process of converting field corn into cornmeal and flour involves several steps.
First, the field corn is harvested and dried to remove excess moisture. Next, the kernels are removed from the cob and processed into a fine or coarse texture, depending on the desired consistency. Cornmeal can be made from degerminated corn, which has had its germ removed, or from whole kernel corn, which retains its germ.
To make flour, field corn is milled into a finer powder using specialized equipment such as stone grinders or roller mills. The resulting flour can be used in baked goods like cornbread, muffins, and bread. Cornmeal and flour are often used interchangeably, but they have distinct textures and flavors. Knowing the difference between these two products will help you choose the right one for your recipe.
Some popular types of cornmeal include fine or medium grind, which is suitable for baking cornbread, and coarse or polenta-style, which is better suited for savory dishes like risottos or side dishes. When using field corn flour in recipes, note that it can be more dense than wheat flour, so you may need to adjust the ratio of liquid ingredients.
High-Fructose Corn Syrup (HFCS) Production
Field corn is processed into High-Fructose Corn Syrup (HFCS), a widely used sweetener in food products. The production process involves several steps to convert the starches in field corn into fermentable sugars, which are then converted into glucose and fructose.
The first step in HFCS production is wet milling, where field corn kernels are soaked in water to break down their outer layers. The resulting mixture, called steepwater, contains a high concentration of starch, protein, and fiber. The starch is then separated from the other components through centrifugation or filtration, leaving behind a starchy liquid.
The starchy liquid is then converted into glucose using enzymes such as amylase. The glucose solution is filtered and concentrated to create a syrup-like consistency. Finally, the syrup is treated with an enzyme called glucose isomerase, which converts some of the glucose molecules into fructose, resulting in the production of HFCS. Today, over 70% of the world’s food products contain HFCS as an ingredient.
When shopping for products containing HFCS, be mindful that it comes in different grades, including HFCS-55 and HFCS-90, which have varying levels of glucose and fructose content.
Industrial Applications of Field Corn
Field corn has a multitude of uses beyond the dinner plate, and its industrial applications are fascinating. In this section, we’ll explore some of the most surprising ways it’s used in everyday life.
Ethanol Production from Field Corn
Converting field corn into ethanol is a multi-step process that involves several stages. The first step is harvesting and processing the corn to extract its starch content. This starch-rich feedstock is then mixed with enzymes, water, and heat to break down the complex carbohydrates into fermentable sugars.
The resulting mixture is then transferred to a fermentation tank where microorganisms convert the sugars into ethanol through a process called anaerobic digestion. The fermented broth is next distilled and separated from the liquid waste, producing a concentrated ethanol solution.
The final step involves diluting the ethanol solution with water to produce anhydrous ethanol, which can be blended with gasoline for use as a biofuel or further processed into other products such as ethylene glycol or biodiesel. According to the Renewable Fuels Association, ethanol production from field corn has increased significantly over the years, with the US alone producing over 14 billion gallons in 2020.
To put this process into perspective, consider the following: a single acre of corn can produce up to 450 gallons of ethanol per year.
Biodegradable Plastics and Other Products
Field corn is not just for food and animal feed; it’s also a versatile crop that can be used to create a variety of industrial products. One such application is the production of biodegradable plastics. These plastics, made from polylactic acid (PLA), are derived from field corn starch through a fermentation process.
The benefits of biodegradable plastics are numerous. For one, they reduce plastic waste and minimize environmental pollution. When disposed of, these plastics break down naturally into carbon dioxide and water, unlike traditional plastics that can take hundreds of years to decompose. Biodegradable plastics have a wide range of applications, including packaging materials, disposable cutlery, and bags.
The production process involves converting field corn starch into glucose through hydrolysis, which is then fermented by microorganisms to produce PLA. This PLA can be molded into various shapes and forms, making it an ideal substitute for traditional plastics. Companies like Cargill and NatureWorks are already using biodegradable plastics in their products, demonstrating the potential of this technology.
In addition to bioplastics, field corn is also used to create other industrial products such as bio-based lubricants, adhesives, and textiles. These applications not only reduce our reliance on fossil fuels but also provide a more sustainable way forward for industries that rely heavily on plastic materials.
Environmental Impact of Field Corn Agriculture
Field corn agriculture has a significant impact on our environment, from water pollution to soil degradation. Let’s take a closer look at how field corn production affects our ecosystem.
Soil Erosion and Conservation Efforts
Field corn farmers face numerous challenges, but one of the most significant is soil erosion. This occurs when the topsoil is worn away by wind and water, exposing deeper layers that are less fertile. It’s a major concern because it can lead to reduced crop yields, decreased soil quality, and even land degradation.
Soil erosion can be caused by various factors, including intensive farming practices, inadequate soil cover, and lack of terracing or contour farming. To mitigate this issue, farmers employ several conservation strategies. These include using no-till or reduced-till methods, which minimize soil disturbance and preserve organic matter.
Crop rotation is another effective technique for preventing soil erosion. By alternating between different crops, farmers can break disease cycles, replenish nutrients, and maintain soil structure. Additionally, incorporating cover crops into their rotation can help stabilize the soil and reduce erosion risks.
In regions with high erosion rates, contour farming or terracing might be necessary to prevent further damage. These methods involve creating flat or gently sloping surfaces on hillsides to reduce runoff and retain topsoil.
Water Usage and Management in Field Corn Production
Field corn is one of the most widely grown crops globally, and its production has significant implications for water usage. On average, a single acre of field corn requires approximately 20-30 inches of water throughout its growth cycle. This can vary depending on factors like climate, soil type, and crop management practices.
Efficient irrigation systems are crucial to minimize water waste in field corn cultivation. One effective approach is drip irrigation, which delivers water directly to the roots of the plants, reducing evaporation and runoff. Another strategy is deficit irrigation, where farmers apply water at a rate that matches the crop’s needs, rather than providing excess water.
In some regions, rainwater harvesting techniques are also employed to supplement irrigation water. For instance, in areas with high rainfall during certain months, excess water can be stored in ponds or reservoirs for later use. By adopting such practices, farmers can reduce their water footprint and promote more sustainable field corn production.
Economic Significance of Field Corn
Field corn plays a vital role in the global economy, providing income for millions of farmers and fueling industries from food production to biofuels. Let’s explore its economic impact in more detail.

These agreements have reduced tariffs and facilitated trade among member countries. In 2019, the US exported over $4 billion worth of field corn to Mexico alone, with the majority coming from Iowa and Illinois.
Another key player in shaping field corn exports is the Trans-Pacific Partnership (TPP), now known as the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP). This agreement has opened up new markets for US field corn producers in countries like Japan and Vietnam. The CPTPP has also led to increased competition among member countries, driving down prices and improving efficiency.
The United States-Mexico-Canada Agreement (USMCA) has had a significant impact on the field corn trade between these three countries. The agreement has reduced tariffs on field corn from 15% to 10%, making it more competitive in the market. In addition, the USMCA has introduced new rules of origin for grains, which have simplified the process of determining whether field corn meets the requirements for duty-free entry.
For instance, under the USMCA, if a shipment of field corn originates from the US and is transported through Canada or Mexico to its final destination, it can be considered as originating from one of these countries. This has opened up new opportunities for farmers in these countries to export their field corn without facing high tariffs.
The US field corn industry stands to benefit significantly from favorable trade agreements. To navigate these agreements effectively, producers and exporters should stay informed about the terms and conditions of each agreement. They can also work closely with government agencies, trade organizations, and other stakeholders to ensure compliance and take advantage of the opportunities presented by these agreements.
