2015 Edwin Frankel Award for Best Paper in Lipid Oxidation and Quality

The article titled “Impact of free fatty acids and phospholipids on reverse micelles formation and lipid oxidation in bulk oil” has been selected for the 2015 Edwin Frankel Award for Best Paper in Lipid Oxidation and Quality (Click here for the information). The papaer was co-authored by BIOTEC researcher, Dr. Atikorn Panya, along with Dr. Ketinun Kittipongpittaya, King Mongkut’s University of technology North Bangkok (KMUTNB) and Prof. Eric Decker and Prof. David Julian McClements from University of Massachusetts Amherst. The article was published in the Journal of the American Oil Chemists’ Society, the leading source for technical papers related to the fats and oils industries.

In this study, the effects of free fatty acids on changes in the critical micelle concentration (CMC) of 1,2-Dioleoyl-sn-glycero-3-phosphocholine (DOPC) in stripped corn oil (SCO) were determined by using the 7,7,8,8-tetracyanoquinodimethane solubilization technique. Physical properties of DOPC reverse micelles in the presence of free fatty acids in bulk oils were also investigated by the small angle X-ray scattering technique. Results showed that free fatty acids could impact on the reverse micelle structure of DOPC in bulk oils. Moreover, free fatty acid decreased pH inside reverse micelle as confirmed by the NMR studies. The oxidation studies done by monitoring the lipid hydroperoxide and hexanal formation revealed that free fatty acids exhibited pro-oxidative activity in the presence and absence of DOPC. Different types of free fatty acids had similar pro-oxidative activity in bulk oil.
