The new method for the determination of lipid deterioration has been developed by HPLC-electrochemical (HPLC-EC) detector. The use of an EC detector made it possible to measure the hydroperoxy group directly. A linear relationship was found between the peak area and content of trilinoleoyl monohydroperoxide (TL-MHP) in the range from 0.109 to 54.9 nmol from HPLC detector (correlation coefficient= 0.997). The lowest detectable level of TL-MHP was estimated to be 10.9 pmol. A linear relationship was observed between peroxide value of oxidized vegetable oils and the peak areas in the chromatograms obtained by EC detections in the range from 5∼30 meq/㎏.
