Popcorn


A popcorn kernel is actually a seed. Like other seeds, inside it has a tiny plant embryo (a life form in its earliest phase). The embryo is surrounded by soft, starchy material that would give the embryo energy for growing into a plant. A hard, glossy shell protects the outside of the seed.
The soft, starchy material holds some water. When the kernel is heated to a high heat (200c), the water inside the kernel turns into steam. The pressure from the steam causes the kernel to explode. The soft starch inside bursts out at about 40 times its original size, turning the kernel inside out. This creates the fluffy white area of a popped kernel.
The ideal popcorn kernel contains about 14 percent moisture. If the popcorn is much drier, it will not pop. Popcorn kernels should be kept in a tightly sealed jar so that they will not dry out.
