Recently, aldehydes such as hexanal (HEX) and propanal have been used as indicators of oil oxidation.
From 11 aldehydes identified, nitrate level had a significant effect on the 2-pentanal, hexanal, heptanal, octanal, and propanal 2-methyl-3-phenyl at levels of p < 0.
Furthermore, an increased amount of sinapic acid is reported to produce less quantity of propanal (secondary oxidation product) at low tocopherol concentration and larger quantity at high levels.
Dadas las pocas mediciones a nivel nacional y por la importancia de este tipo de sustancias, este estudio tuvo como objetivo determinar la concentracion del formaldehido, el acetaldehido, el propanal, el butanal, el hexanal y el heptanal, en el aire de la Reserva Biologica Monteverde y del Campus Omar Dengo de la Universidad Nacional, durante la epoca seca y transicion a la epoca lluviosa, debido a que tales lugares representan una zona boscosa y una zona urbana y, asi, comparar los dos escenarios.
omega]]-di-Boc-guanidyf) propanal with Fmoc hydrazine, while the required carbonyl compound was prepared by guanylation of 3-amino-propanol with N,N'-bis-Boc-S-methylisothiourea, followed by oxidation with the Dess-Martin reagent [12].

The research, "Room-temperature oxidation of propanal using catalysts synthesized by electrochemical deposition," was published in the August 2009 issue of Transactions of the ASABE.
They also wanted to evaluate the effects of ozone treatments on aerobic plate counts and lipid oxidation, assessed as thiobarbituric acid reactive substances (TBARs) and headspace propanal, through 10 days of refrigerated storage at 2 C.
