General description

cis-4-Heptenal is one of the major carbonyl compounds found in oxidized lipid materials. It occurs in dairy products and seafood. cis-4-Heptenal has also been associated with the off-flavors in fish oil.

Application


  • Microbial community succession and their relationship with the flavor formation during the natural fermentation of Mouding sufu.: This study explores the role of cis-4-Heptenal in the flavor formation during the fermentation of Mouding sufu, highlighting its importance in food chemistry and microbial interactions (Chen et al., 2023).

  • Kinetics studies of the gas-phase reactions of NO3 radicals with series of 1-alkenes, dienes, cycloalkenes, alkenols, and alkenals.: The paper discusses the reaction kinetics of cis-4-Heptenal with NO3 radicals, providing valuable data for atmospheric chemistry and the study of air pollutants (Zhao et al., 2011).

Detection thresholds are used routinely to determine the odour-active compounds in foods. The composition of a food matrix, such as hydrophobicity or solids content, has an impact on the release of flavour compounds, and thus on thresholds. In the case
