Popcorn vs. Field Corn: What is the Difference Between the Two?

There are several types of corn.

Some kinds of corn are best for eating, other types are good for making Oh Sooo Buttery and Classic Kettle Popcorn, while other varieties are only used for animal feed. So while all ears of corn look similar, they’re really quite diverse.

In today's post, we’re specifically going to talk about the differences between regular corn and popcorn.

Let’s dive right in and see what makes these whole grains so unique:  

What Are the Primary Differences Between Corn and Popcorn?

Regular corn and popcorn may be the same plant at their core. But they are grown differently and serve different purposes.

The popcorn plant is known as Zea Mays Everta. It’s a specific type of corn that has dense kernels. Those kernels pop under pressure, turning into the snack you know and love.

Popcorn kernels are much drier than regular corn kernels — trust us, you wouldn’t want to take a bite out of an ear of popcorn! It lacks the moisture content and flavor of sweet field corn.

Regular corn also has a different type of endosperm. It's on the inside of the kernel, and is what makes popcorn pop when placed under enough pressure.

Types of Popcorn Plants

There are several varieties of popcorn plants. All pop into white, fluffy popcorn, but each also has its individual characteristics. The plants may vary in size and color and even the popcorn it creates will be a little different. 

FUN FACT: Most popcorn plants are grown in the Midwest. The kernels we use for our popcorn kits come from family-owned farms in Iowa and Missouri. This means you're guaranteed fresh, flavor-packed goodness with every handful of our stovetop popcorn.

Pearl Popcorn

This type of popcorn has a large, round shape. It’s slightly yellow and keeps that hue even after it pops. Pearl popcorn is the kind of popcorn you usually find in movie theaters since its kernel is durable. This starchy popcorn holds up under even the heaviest movie theater butter seasoning.

Pearl popcorn expands impressively when cooked. Unpopped kernels grow to be about 45 times their original size. It's easy to see why it's so popular, right?

Rice Popcorn 

Rice popcorn has elongated kernels that are slightly smaller than pearl popcorn. You usually see this kind of popcorn in pre-bagged or microwave popcorn bags.

When rice popcorn pops, its color is white. The popcorn kernels grow around 40 times their original size, with a light, fluffy, and slightly crunchy texture. Rice popcorn is softer than pearl popcorn and can only hold lighter seasonings like a pinch of salt or butter.

Different Popcorn Colors

Popcorn comes in a lot of colors. Blue, yellow, red, white, and even pink kernels exist.

While the color of the popcorn doesn't affect texture, it can affect its taste. Colored popcorn tends to have a stronger corn-like taste while white and yellow popcorn are more neutral. Stick to the latter two if you really want your seasonings to shine.

Types of Corn Plants

Corn plants are also diverse. Every plant will produce corn that varies in taste, texture, and color. A lot will depend on where the corn is grown and what it was planted for.

Field corn and sweet corn are among the most common types of corn plants. These plants create kernels that don’t dry out as much as popcorn kernels. They’re best for eating or for animal feed.

Here's a closer look at both varieties:

Field Corn

This is the most common type of corn grown in the United States. It's what likely comes to mind when you think of corn — tall green stalks and bright yellow cobs.

Field corn can be divided into two categories: dent corn and flint corn.

Dent corn has a high starch content and is typically used as animal feed or in food manufacturing. It’s also used to make corn syrup, an ingredient in a lot of processed food.

On the flip side, flint corn is known for its unique colors. Ever hear of a kind of corn called Indian corn? If you haven't, it comes in reds, blues, and pinks and may just be the prettiest corn out there!

Sweet Corn

Sweet corn is the corn you see in grocery stores and at roadside stands. It's mainly grown for human consumption and typically enjoyed during summertime when it's in season. But you can buy it canned to eat it all year round. 

Sweet corn has a high sugar content, making it taste sweeter than other types of corn (hence the name). It’s much tastier than starchy field corn and is the kind of corn you want to slather with butter and eat right off the cob.

Corn vs Popcorn FAQs

Can regular corn pop like popcorn?

Nope, regular corn doesn’t pop like popcorn kernels. Popcorn kernels have a lower moisture content than regular corn. The endosperm on regular corn will not pop under pressure as it does on popcorn. You can try popping regular corn but you’ll likely just end up with a bowl full of burnt corn kernels.

Is popcorn considered a vegetable?

Popcorn is considered a whole grain. Every type of corn is a grain; however, many grains are considered to be fruit. So despite what you might have thought, corn isn't actually a vegetable.

Do you dry popcorn before or after you harvest it?

Popcorn kernels need to be dried on the cob before harvest. One way to tell if the popcorn cob is ready for harvesting is by checking the husk. When the husk is dry and all the kernels in the corn are dry, it’s ready. The drying process can take one week or longer depending on the weather.

Are corn and popcorn healthy?

Corn and popcorn both provide some health benefits but they aren’t always healthy.

Field corn is highly processed before it’s ready to use. This makes it lean toward the unhealthy side, especially since it’s often turned into sugary syrup. Sweet corn, though, can be a great source of antioxidants, vitamins, and minerals.

Popcorn, on the other hand, isn’t inherently unhealthy. It's the seasoning and oil people add that can take away the beneficial carbohydrates and decrease its nutritional value.
