2-Hexylthiophene

Description

Thanksgiving traditionally means turkey; and turkey means the aromas that waft throughout the house while it’s roasting. But what’s responsible for these delicious smells?
Answer: the Maillard reaction. Discovered by French chemist Louis-Camille Maillard in 1912, the “reaction” is actually a complex series of steps that begins with the interaction between carbonyl groups of open-chain sugars and amine groups of amino acids to form N-aldosylamines. Eventually, depending on the food being heated, the sequence ends with the creation of multiple chemical entities, including many heterocyclic compounds.
These reactions occur when foodstuffs are heated to 140–165 oC. In addition to the aromas they produce, they are responsible for browning baked, grilled, or roasted foods such as breads, vegetables, and meats. Browning is accelerated in an alkaline environment.
All of which brings us back to turkey. As with other roasted meats, the Maillard reaction produces numerous compounds. Two that have been reported in the literature are 2-pentylpyridine and 2-hexylthiophene, shown here. (No systematic study of all of the Maillard products from turkey appears to have been conducted.)
So, when your host serves you delicious roasted turkey with all the fixings, please compliment her or him on an excellent helping of 2-pentylpyridine and 2-hexylthiophene.
