General description

trans-2-Heptenal is a volatile flavor constituent identified in heated butter and tomato.

Application


  • Studies on the reaction of trans-2-heptenal with peanut proteins: This research examines the interactions between trans-2-heptenal and peanut proteins, providing significant insights into food chemistry and the stability of flavor compounds in food products. The study reveals potential implications for biochemists interested in food allergenicity and protein-aldehyde interactions (Globisch et al., 2014).

  • An experimental study of the gas-phase reactions of NO3 radicals with a series of unsaturated aldehydes: trans-2-hexenal, trans-2-heptenal, and trans-2-octenal: This paper explores the reactivity of trans-2-heptenal with NO3 radicals in the gas phase, contributing to a better understanding of atmospheric chemistry and the environmental behavior of volatile organic compounds. Such information is crucial for biochemists studying the environmental impacts of organic compounds (Kerdouci et al., 2012).

In the present study, the aldehyde-induced pro-oxidative activity of xanthine oxidase was followed in an accelerated raw milk system using spin-trap electron spin resonance (ESR) spectroscopy. The aldehydes acetaldehyde, propanal, hexanal, trans-2-hexenal, trans-2-heptenal, trans-2-nonenal, and 3-methyl-2-butenal were all found to

Derivatization is frequently used in liquid chromatography-mass spectrometry (LC-MS) to improve the ionization characteristics of analytes, and facilitate their structural elucidation and quantification. However, the off-line derivatization process usually requires more analysis time. Therefore, the present work develops a novel
