Applicazioni


  • Induction of a wide range of C(2-12) aldehydes and C(7-12) acyloins in the kidney of Wistar rats after treatment with a renal carcinogen, ferric nitrilotriacetate.: Toyokuni et al. explore the biochemical impact of ferric nitrilotriacetate, a renal carcinogen, on the generation of various aldehydes including trans-2,cis-6-Nonadienal in the kidneys of Wistar rats. This research highlights the role of oxidative stress and lipid peroxidation in renal carcinogenesis (Toyokuni et al., 1997).

The ability of nonacidified, refrigerated pickled cucumbers to produce the fresh cucumber flavor impact compounds (E,Z)-2,6-nonadienal and (E)-2-nonenal declined during storage. Production of these compounds decreased as the pH of refrigerated cucumbers was reduced. Despite the fact that the concentrations
