General description

Isobutyl alcohol is a water-soluble aliphatic alcohol that can be used as a flavoring agent. It has been identified as one of the aroma/flavor compounds produced by Saccharomyces cerevisiae during the semi-aerobic fermentation of grapes to form wine.

Application


  • Volatiles from nutritional fungal symbiont influence the attraction of Anisandrus maiche (Coleoptera: Curculionidae) to ethanol-baited traps.: This investigation revealed that volatiles emitted by fungal symbionts impact the attraction of Anisandrus maiche to ethanol-baited traps. The study suggests potential applications in pest management strategies by utilizing isobutanol and other volatiles (Tobin et al., 2024).
