How do they explode i corn kernels and turn into popcorn?
The heat transforms the water present in the corn kernel into steam and despite the strong internal pressure no crack is formed: the outer shell of the corn kernel (the pericarp) is extremely hard and does not allow steam to escape.
The grain is thus transformed into a small pressure cooker: it is the “high pressure + high temperature” combination that transforms the corn grain into popcorn! When the grain reaches an internal temperature of 180 ° C, the starch turns into that beautiful white cloud that we callpop corn.
