The Chemistry
Maltyl isobutyrate is an ester formed from maltol and isobutyric acid. As a synthetic compound, it’s typically produced through esterification reactions under controlled conditions. The molecule’s structure allows for both volatile top notes and persistent sweet characteristics. While not found in nature, it mimics compounds formed during Maillard reactions in cooked foods.
