Popcorn Pyrazine

Popcorn pyrazine, specifically 2-acetylpyrazine, is an aromatic compound responsible for the distinctive warm, nutty, and buttery scent of freshly popped popcorn.

It is part of the pyrazine family, a group of nitrogen-containing heterocyclic compounds known for their roasted, nutty, and sometimes earthy aromas.

It is extremely powerful. We love it for how it makes your surroundings smell like you have just been transported to a cosy cinema.

Key Characteristics of Popcorn Pyrazine (2-Acetylpyrazine)

• Chemical Formula: C6H6N2O
• Aroma: Nutty, roasted, buttery, popcorn-like
• Occurrence: Found naturally in popcorn, roasted coffee, cocoa, baked goods, and grilled meats
• Uses: Commonly used in food flavorings and fragrance formulations to enhance roasted or nutty notes

How It Forms in Popcorn

When popcorn kernels are heated, the Maillard reaction occurs between amino acids and reducing sugars, leading to the production of various flavor compounds, including 2-acetylpyrazine. This reaction is also responsible for the golden-brown color and rich aroma of cooked foods.

Other Sources & Applications

• Food Industry: Added to snacks, cereals, and bakery products to enhance flavour
