Popcorn smell is primarily caused by a compound called 2-Acetyl-1-pyrroline (2-AP). This organic compound is produced when heat causes the sugars and amino acids in the popcorn kernels to undergo the Maillard reaction, a form of non-enzymatic browning. The result is the distinct and appealing aroma that many associate with freshly popped popcorn.
