Chemical investigation demonstrates the reaction kinetics and aqueous reactivity of malonaldehyde, highlighting its mechanism as a marker for food lipid oxidation.

Key Points

To investigate the formation kinetics, aqueous properties, and chemical reactivity of malonaldehyde to assess its effectiveness as a measure of lipid oxidation in foods.
Analyzed the kinetics of malonaldehyde synthesis via acid hydrolysis of bis-(diethylacetal).
Calculated theoretical reactivity using the frontier electron method from molecular orbital calculations.
Assessed aqueous ionization constants, polymerization, chelation with ferric ions, and adduct formation with bisulfite, dimedone, and 2,4-dinitrophenylhydrazine.
Characterized the hydrolysis rate, ionization constants, and polymerization behavior of malonaldehyde in aqueous environments.
Demonstrated complex formation and reactivity profiles with bisulfite, 2,4-dinitrophenylhydrazine, dimedone, and ferric chelates consistent with molecular orbital predictions.
Identified the operational effects of acidification on isolating malonaldehyde from food matrices to quantify lipid oxidation.
