Abstract:

ABSTRACT: In this study, the antioxidant capacity during UV exposure has been investigated by using a laser-based trace gas detector for the detection of gaseous ethylene as an indicator for lipid peroxidation. Biocream was used as a control and ascorbic acid, butylated hydroxytoluene, phloroglucinol and hydroquinone were added as antioxidants in a mixing concentration of 2.5% (w/w). The experimental results show that there is a decrease in the number of ROS due to the presence of antioxidants, from which ascorbic acid is the most effective. The detection method offers a direct and on-line way to evaluate the capability of antioxidant in reducing the harmful effect of the UV radiation.
