Debunking the Cereal Myth: The Core Ingredient of Cornflakes
Contrary to a common misconception, the iconic crunchy breakfast cereal known as cornflakes is made primarily from milled corn, also known as maize. The manufacturing process transforms this starchy grain into the light, golden flakes that have been a breakfast staple for over a century. The confusion often arises because many flake-based cereals exist, some of which are indeed made from wheat, leading consumers to generalize about all such products.
The Kellogg Company's founders, Dr. John Harvey Kellogg and his brother Will Keith Kellogg, developed the original recipe as a wholesome and easily digestible food for patients at the Battle Creek Sanitarium. This innovation was based on a different grain, but Will Kellogg's later experiments and business ventures cemented the version made from toasted maize as a commercial success.
The Manufacturing Process: From Maize to Flake
Manufacturing cornflakes is a precise process that begins with the right type of corn. Dent corn, or field corn, is preferred for its high starch content.
Here's a step-by-step breakdown of how it's made:
- Milling: The maize kernels are milled into grits.
- Cooking and Flavoring: The corn grits are cooked in large vats with other ingredients like sugar, salt, and malt flavoring.
- Drying: After cooking, the grits are dried to reduce their moisture content.
- Flaking: The dried corn grits are passed through heavy-duty rollers that flatten them into thin flakes.
- Toasting: The flakes are then toasted to achieve their characteristic crispness and golden color.
- Fortification: Many brands fortify their cornflakes with additional vitamins and minerals, such as iron, zinc, and B vitamins.
The Gluten Connection: Why Cornflakes Aren't Always Gluten-Free
While the main ingredient is corn, a naturally gluten-free grain, this does not mean all cornflakes are safe for those with celiac disease or a gluten intolerance. The key lies in one specific additive: barley malt extract.
Barley is a gluten-containing grain, and its malt extract is used in many commercial cornflake recipes for flavor. Because this additive is a source of gluten, popular brands like Kellogg's Corn Flakes are not gluten-free. However, some brands intentionally produce gluten-free versions, and these are safe to consume. Individuals with a gluten allergy or sensitivity should always check the ingredient label carefully, as even products without barley malt could risk cross-contamination from facilities that also process wheat.

Cornflakes vs. Wheat Flakes: A Comparison
To better understand the difference, consider the table below comparing the fundamental characteristics of cornflakes and wheat flakes.
| Feature | Cornflakes (Standard) | Wheat Flakes (Standard) | 
|---|---|---|
| Primary Ingredient | Milled corn (maize) | Whole wheat grain | 
| Gluten Content | Contains barley malt, so typically not gluten-free. | Contains gluten naturally, so not gluten-free. | 
| Fiber Content | Lower fiber content, as the bran is often removed during processing. | Higher fiber content, especially when made from whole wheat grain. | 
| Nutritional Profile | Often fortified with vitamins like B vitamins, iron, and zinc. | Rich in natural fiber, B vitamins, and iron, especially from whole grain versions. | 
| Texture and Flavor | Crispy and light with a distinct flavor from the maize and added sugar/malt. | Nutty, heartier, and chewier texture from the whole wheat bran. | 
Which Flake is Right for You?
Choosing between cornflakes and wheat flakes often comes down to dietary needs and personal preference.
For those seeking a gluten-free option, most major brands of cornflakes are off the table due to the barley malt, but special gluten-free versions are available from brands like Nature's Path and Nestle. Wheat flakes are never an option for celiac disease patients due to their inherent gluten content.
In terms of nutritional value, whole wheat flakes generally offer more dietary fiber, which promotes digestive health and can aid in weight management by providing earlier satiety. Standard cornflakes, while often fortified with nutrients, tend to be lower in fiber and may have a higher glycemic index due to their processing and added sugars.
Conclusion
In conclusion, the simple answer to whether cornflakes are made of wheat is no, they are made from corn. However, for those with gluten restrictions, the matter is more complex due to the use of barley malt flavoring in many commercial recipes. Understanding the different grains and additives used in breakfast cereals is essential for making informed dietary choices. Always check the ingredient list and look for certified gluten-free labels if you have a sensitivity or allergy. While both offer a quick breakfast option, they differ significantly in their ingredients, fiber content, and gluten status.
