How Does Popcorn Explode?

A handful of popcorn suddenly bursts out of their shells and turns into something much more magnificent. As the Egyptians perform their transformation, a small explosion sound accompanies them. Corn kernels, expanding up to 50 times their size, become soft and chewy together with beneficial nutrients such as fiber and antioxidants; They turn into super heroes of snack foods.

So how do these corn kernels, which are hard enough to crack teeth, turn into a soft film snack?

A popcorn kernel contains three key ingredients. These consist of the outer hard shell known as the seed membrane, a middle layer known as the besidoku, and the innermost part known as the seed or embryo. Each of the popcorn is packed with water and starch. When the popcorn kernel gets hot, the water inside turns into steam. This water vapor creates pressure inside the core. As the pressure builds up, the starch begins to soften. When the seed reaches about 177 degrees, the shell or seed membrane bursts at this pressure created and the starch exceeds the limits of the shell.

So if each of the beans burst under heat and pressure, why are there always seeds that don't explode at the bottom of the bowl?

Each seed needs a moisture level of about 14 percent. If the water content falls below this level, the vapor formed decreases and the possibility of the beans to burst and expand by entering under sufficient pressure is reduced.

But these beans are more than just a tasty snack. Popcorn is very nutritionally dense thanks to its high polyphenol levels. Polyphenols, which are micronutrients found in plant foods, are rich in antioxidants that protect cells in the body from destruction. According to a 2012 study, one serving of popcorn contains 300 mg of polyphenols; In other words, a portion of milk is almost three times the amount in corn and almost twice the amount in a portion of fruit.

The reason why popcorn seeds contain so much nutrients is that they contain an average of 4 percent water compared to 90 percent in fruits and vegetables. When the beans burst, all that's left is starch and shell with fiber and polyphenols. This fiber transports polyphenols into the bloodstream during digestion and in turn positively affects the health of the person eating popcorn.

With three and a half grams of fiber per three-cup serving, popcorn also tops the healthy, high-fiber food list of the nonprofit Mayo Clinic medical center.

Ready to experiment now? The next time you go to the grocery store or grocery store, leave the microwave bags on the shelf and whoever shoppers buy them only popcorn beans.
