Popcorn is one of the most beloved and iconic snack foods across the globe. That familiar popping sound coming from the kitchen signifies cozy movie nights, sports games, and family gatherings. While popcorn can be prepared in several ways, microwave popcorn reigns supreme in terms of convenience and ease. Simply unwrap a packet, pop it in the microwave for a few minutes, and enjoy piping hot, perfectly popped corn straight from your own kitchen.
But behind this simple snack lies some fascinating history, science, and innovations that have led to microwave popcorn becoming a pantry staple today. This guide will explore the origins of popcorn, how microwave popcorn is made, nutritional information, tips for making perfect popcorn every time, and some delicious flavored recipes to try at home. Let’s get popping!
A Brief History of Popcorn
Archaeologists have discovered that popcorn was being enjoyed over 6,000 years ago in Peru. In fact, popcorn is one of the oldest snack foods known to man. The oldest ears of popcorn ever found were discovered in New Mexico and date back approximately 5,600 years.
Popcorn was an important food for many Native American tribes who introduced the first European settlers to this fluffy snack in the 16th century. At the first Thanksgiving dinner in 1621, popcorn was likely served alongside other harvested foods.
As popcorn grew in popularity across America over the next few centuries, street vendors would sell it freshly popped in paper cones. Popcorn became ingrained in American snacking culture, becoming a popular snack to munch on at circuses, fairs, and movies theaters.
However, popcorn preparation remained tedious work until the mid-20th century. Kernels had to be hand-popped in pots or on the stove, requiring constant attention to prevent burning. Everything changed when the first electric popcorn maker was invented in 1911 by Charles Cretors. His machine used steam and heating coils to efficiently pop corn in commercial quantities.
The next major advancement arrived in 1945 when Percy Spencer invented the microwave. After the first commercial microwaves hit the market in the 1950s, food scientists got to work creating the first microwave popcorn. In 1981, General Mills employee Frederick W. Hervey patented the disposable microwave popcorn bag that could withstand the intense heat required to pop corn and eliminated the need for oil or butter. And with that, microwave popcorn was born!
Today over 17 billion quarts of popped popcorn are consumed around the world each year. Microwave popcorn now accounts for around 70% of popcorn sales thanks to its irresistible convenience factor. Let’s look at how this popular snack is made.
How Microwave Popcorn Pops
Part of the appeal of microwave popcorn is that it seems to magically transform from a flat little bag into a bowl of fluffy popcorn in mere minutes. But the perfect popcorn pop requires some clever engineering!
Inside each bag is a specific popcorn formulation designed for microwave preparation. The bag itself has a multilayer construction. The inner layer that comes in contact with the popcorn contains heat-resistant enamel to withstand temperatures of around 400°F needed to properly pop the corn.
The middle layer provides an airspace that allows steam to build up and circulate to evenly pop all of the kernels. Finally, the outer paper layer enables optimal heat absorption from the microwave.
The bag is also lined with the optimal amount of popcorn kernels, usually around 3.4 ounces. Popcorn requires a precise moisture content of 13.5-14% to pop properly. The kernels are lightly toasted which removes some moisture and brings them to ideal popping moisture levels before packaging.
The magic ingredient is the oil. Most microwave popcorn contains a small amount of oil, usually coconut, soybean, or canola oil. A little oil goes a long way – around 1/2 tablespoon is evenly distributed over the entire bag. When the microwave heats up, the oil becomes super-hot which quickly heats the water inside the kernels to around 400°F until the steam pressure causes the kernels to explode into popcorn.
The packaging is designed so that once the popping slows down and reaches optimal completion, the steam vents to prevent overcooking. And just like that, you have a piping hot bag of popcorn in just 2-4 minutes! Now let’s look at how microwave popcorn stacks up nutrition-wise.
Nutritional Content of Microwave Popcorn
One of the biggest concerns consumers have about microwave popcorn is whether it’s healthy or not. Plain popcorn itself is a nutritious, whole grain food that is low in calories and high in fiber. However, microwave varieties do undergo processing and contain added ingredients that impact the nutrition content.
Here is the typical nutritional value for a 1 ounce (about 3 cups) serving of microwave popcorn:
| Nutrient | Amount | % Daily Value |
|---|---|---|
| Calories | 55 | 3% |
| Total Fat | 3 g | 5% |
| Saturated Fat | .5 g | 3% |
| Trans Fat | 0 g | |
| Cholesterol | 0 mg | 0% |
| Sodium | 75 mg | 3% |
| Carbohydrates | 7 g | 2% |
| Fiber | 1.2 g | 4% |
| Sugars | 0 g | |
| Protein | 1 g |
As you can see, a single serving provides a decent amount of volume and satisfaction for minimal calorie and fat costs. Where microwave popcorn loses some nutritive value compared to air-popped is the addition of oil and salt. The amount of sodium per serving lands around 3-5% your daily recommended intake.
Many brands now offer low-fat and light varieties with even fewer calories and less salt and oil. However, the regular butter flavors shouldn’t pose a problem when enjoyed in moderation as part of an overall balanced diet.
Microwave popcorn makes for a convenient snack that’s far lower in calories, fat, and sodium compared to other grab-and-go snacks like chips, cookies, or candy. Now let’s go over some tips to make perfect popcorn every time you microwave it.
Tips for Making Perfect Microwave Popcorn
While microwave popcorn takes out most of the guesswork, there are still some simple steps to follow for popcorn perfection:
- Don’t try to microwave more than 1 bag at once – Cooking multiple bags together prevents the bags from spinning properly and leads to uneven cooking. Pop bags one at a time.
- Listen for the popping to slow before removing – Once the popping slows to 1-2 seconds between pops, your popcorn is nearing completion. Resist opening the bag prematurely!
- Give the bag a shake halfway through – Shake the bag once halfway through cooking to redistribute unpopped kernels so all sides get evenly heated.
- Make sure the bag fully inflates – A fully inflated bag when removed from the microwave ensures that the moisture has converted to steam and popped all kernels. Collapsed sections mean unpopped kernels remain.
- Allow the bag to rest before opening – Letting the bag sit for 30-60 seconds after cooking gives time for any remaining steam to fully vent and prevents steam burns.
- Handle with care when opening – Use scissors to cut open bags and peel back slowly. Beware of escaping steam which can still be quite hot.
- Transfer to a bowl right away – Empty the popcorn into a serving bowl so it won’t oversteam in the bag. Enjoy it fresh!
Follow these steps and you’ll be rewarded with light and fluffy popcorn results every time. Now let’s look at how to spice things up with flavored popcorn recipes.
