What makes popcorn pop?

The reason why popcorn pops is the water trapped inside its kernel. If the kernel is heated to a high enough temperature, this water will transform into steam. Due to the hard and mostly nonporous shell, the steam has nowhere to go, resulting in a buildup of pressure inside the kernel.

How does a microwave pop popcorn?

The energy from the microwaves makes the water molecules in each kernel move faster, exerting more pressure on the hull until the kernel explodes. The bag that microwave popcorn comes in helps trap the steam and moisture so the corn can pop more quickly.

How does popcorn pop chemistry?

During heating, the corn pericarp acts like a pressure cooker that locks moisture inside the corn kernel. The heated moisture leads to a pressure buildup until the kernel eventually ruptures and pops, essentially turning the kernel inside out and producing the fluffy white product that we eat.

Why do some popcorn kernels not pop?

Popcorn kernels will not pop if they contain too little or too much water moisture inside the kernel. The popcorn kernels which do pop have 14-15\% moisture in the hull and anything less or more will cause the popcorn kernel to not explode. You can test the moisture of your popcorn by using your fingernail.

Does popcorn change mass when popped?

Absolutely. Unpopped kernels contain water. When heated, the water turns to steam which causes the kernel to pop. The mass of that water is lost.

What gives popcorn a coffee like aroma?

Compounds called pyrazines contribute nutty flavours, with 2-acetylpyrazine, whose aroma is itself described as ‘popcorn-like’, cited as a key odorant.

Can popcorn pop in boiling water?

Their moisture content is around 14 percent. The kernel pops when it’s heated because the moisture turns into steam. If you want to make your own half-popped kernels, start with your favorite popcorn kernels and a pot of water. Once the water is boiling, drop the kernels in for around 30 minutes.

What is in popcorn that makes it pop?

Popcorn is made of popped corn. You make it by popping corn, which consists of heating corn kernels until the water trapped inside vaporizes and expands, causing the starches to expand, causing the kernel to explode, or pop. Popcorn is also made out of starches, which are made out of atoms, which are little vibrating packets of energy.

How hot does it have to be for popcorn to pop?

The temperature must be above 300 degrees F for the popcorn to pop. Popcorn has to be at a certain temperature (about 400 degrees F) so that it is possible for the steam pressure inside the kernel to buildup to the point where starch is properly cooked and it can pop (burst) the strong outer casing (pericarp) of the kernel.

How do you pop popcorn without a popper?

How to Pop Popcorn Without a Popper on the Stovetop – Step by Step Take a large saucepan, and let it get hot over a medium-high heat. When the three kernels start to pop, add the rest of the kernels and quickly place a lid on top. Give the pan an occasional shake to keep the kernels from burning.
