Metabolite Identification
Common Nametrans-2-Octenal
Descriptiontrans-2-Octenal is a volatile aldehyde classified as a lipid-derived metabolite. Its chemical structure features a straight-chain hydrocarbon with a double bond between the second and third carbon atoms, contributing to its characteristic aroma. In various fermentation processes, trans-2-octenal has been observed to fluctuate in concentration, with studies indicating a slight increase in its levels while other off-flavor aldehydes are reduced, thereby enhancing overall flavor profiles (PMID:40989104 ). Additionally, during fermentation, trans-2-octenal's concentration decreased significantly, alongside other compounds, while aromatic compounds such as esters and ketones emerged (PMID:40941181 ). This compound has also been linked to the flavor enhancement of cooked rice, highlighting its role in the aroma profile of food products (PMID:40361709 ). Beyond its sensory attributes, trans-2-octenal exhibits bioactive properties, particularly in controlling the soil-borne pathogen Fusarium oxysporum f., demonstrating its potential as a biocontrol agent in agricultural settings (PMID:39815676 ). The effectiveness of trans-2-octenal against pathogens has been validated in various experimental setups, suggesting its utility in both in vitro and field applications (PMID:39815676 ).
