Alkylpyrazines are chemical compounds based on pyrazine with different substitution patterns. Sesame ( Sesamum indicum) is a Flowering plant in the genus Sesamum. Pyrazine is a Heterocyclic Aromatic Organic compound. Pyrazine is a symmetrical molecule with Point group D2h Some alkylpyrazines are naturally occurring highly aromatic substances which often have a very low odor threshold[1] and contribute to the taste and aroma of various foods including coffee and wines. The odor detection threshold is the lowest concentration of a certain Odor compound that is perceivable by the human sense of smell. [2] Alkylpyrazines are also formed during the cooking of some foods via Maillard reactions. The Maillard reaction is a Chemical reaction between an Amino acid and a Reducing sugar, usually requiring Heat.
