What is inside a kernel of popcorn before it pops?
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. With high temperatures, the starch gelatinizes and then expands with the rapid burst of the kernel.
What is inside a corn kernel?
Each kernel of corn is actually a seed that, like most seeds, contains an embryo (a baby plant) and a seed coat for protection. Corn seeds are filled with a starchy endosperm that provides food for the baby plant (it’s stained black in right-half of each kernel in the photo below).
What is the germ of a popcorn kernel?
pericarp
The pericarp is the tough outer shell surrounding a popcorn kernel, and the key to what makes it pop. Inside the pericarp is the germ, or seed embryo. Adjacent to the germ is the endosperm, which contains some trapped water plus soft and hard starch granules that serve as food for the germ when it sprouts.
Can you Remicrowave unpopped kernels?
Toss the unpopped kernels in a paper bag and pop them in the microwave. Your best bet is to place some kernels into a paper bag, put it in the microwave, and knock at least a minute off of the usual popping time.
What chemicals are in popcorn?
Microwave Popcorn and Cancer According to a December 2013 report in Environmental Health Perspectives, microwave popcorn bags contain chemicals called perfluorooctanoic acid (or PFOA), which is the same chemical used in Teflon® nonstick coating, and perfluorooctane sulfonate (or PFOS).
What are popcorns made of?
Popcorn, like all six types of corn, is a cereal grain and originates from a wild grass. Its scientific name is Zea mays everta, and it is the only type of corn to actually pop. Popcorn is made up of three main components: endosperm, germ and the pericarp (also known as hull or bran).

Will birds eat unpopped popcorn kernels?
Popcorn. Believe it or not, many pet birds enjoy snacking on popcorn. You can serve your bird either popped or unpopped kernels. If you choose to serve the popcorn unpopped, boil the kernels for a bit in plain water to soften the tough hulls.
Will birds eat unpopped popcorn?
Does popcorn pop in water?
Wet popcorn kernels will not pop. Always drain the water and pat dry the popcorn kernels before you begin popping. Popcorn kernels will pop very poorly or not at all when they are wet. The only risk when soaking your popcorn kernels is not drying them enough before heating.
Why does popcorn pop in the middle of the kernel?
The fact is that, popcorn pop because of water present in each kernel. The water is stored in the middle of a kernel which is surrounded by a hard outer surface. When the kernel heats up, the water expands and pressure begins to build up. Eventually, the hard surface is not able to withhold the pressure and the corn explodes.
How much water does a kernel of popcorn need to pop?
Each kernel of popcorn contains a small drop of water stored inside a circle of soft starch. Popcorn needs between 13.5-14% moisture to pop. The soft starch is surrounded by the kernel’s hard outer surface.
What kind of plant does popcorn come from?
Popcorn plant (Zea mays everta) is a Native American Plant that is grown only for its taste and amazingly delicious exploding kernels. Farmers grew two type of popcorn, namely: While the pearl popcorn has round kernels, rice popcorn has an elongated kernel.
What happens to the grain of popcorn when it explodes?
The pressure inside the grain will reach 135 pounds per square inch before finally bursting the hull open. As it explodes, steam inside the kernel is released. The soft starch inside the popcorn becomes inflated and spills out, cooling immediately and forming into the odd shape we know and love.
