Definition
ChEBI: A member of the class of pyrazines that is pyrazine in which one of the hydrogens is replaced by an ethyl group. Found particularly in cereals and cereal products, it is present in baked or fried potato, bread, roasted peanuts, and cooked shrimp, as well a cocoa, coffee, and tea. It has a musty, nutty, buttery, peanut odor and a chocolate-peanut taste.

By alkylation of methylpyrazine with methyliodide.
Aroma threshold values
Detection: 4 to 22 ppm. Aroma characteristics at 1.0%: nutty, musky, fermented, coffee, roasted, cocoa and meaty nuances.
Taste threshold values
Taste characteristics at 10 ppm: nutty, musty, casky, woody, potato, earthy and cocoa with a fishy nuance.
General Description
2-Ethylpyrazine is a volatile aroma compound that is mainly formed in food products such as roasted coffee beans or roasted sesame seeds due to the Maillard reaction between sugars and proteins during the roasting process.
