• O/W emulsion
• thermal oxidation
• luminol chemiluminescence
• reactive oxygen species

The luminol chemiluminescence (CL) profile of an oil-in-water (O/W) emulsion during thermal oxidation (60 degrees C) was assessed using the luminol-K-3[Fe(CN)(6)] assay, in which the oxidation species produced by the autoxidation of an O/W emulsion generated CL emission. Increased CL intensity was observed for O/W emulsions prepared using either linseed or corn oil, which was increased by the addition of Fe2+ to the O/W emulsion. The relationship between the CL profile and results obtained by conventional approaches, such as the peroxide value (PV) and thiobarbituric acid (TBA) methods, were compared. Owing to good correlation, between the CL intensity and results obtained by the methods, the CL method might be applicable for estimating the oil oxidizing of an emulsion in thermal oxidation.
