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

The genotoxic effects of the 2-alkenals crotonaldehyde, 2-trans-hexenal and 2-trans-6-cis-nonadienal were studied by cytogenetic methods, analyzing frequencies of sister-chromatid-exchanges, numerical and structural chromosome aberrations and micronucleus induction in human blood lymphocytes and cells of the permanent Namalva line. Crotonaldehyde and
