Botany and Varieties of Popcorn
Popcorn belongs to the species Zea mays everta, a subtype of flint corn distinguished by its hard pericarp, which traps moisture and enables the popping mechanism. Each kernel consists of three main parts: the tough outer pericarp, the starchy endosperm and the germ, which contains oils and proteins essential for high-quality popping.
Popcorn varieties are classified by kernel shape pearl (rounded) or rice (elongated) and color, including yellow, white, blue, red and multicolored heirlooms. Pigmented varieties, such as purple or black popcorn are rich in anthocyanins, giving them higher antioxidant content and increased nutritional value, which also boosts market appeal.
