Trial manufacture of the test paper for the detection of oxidized lipids.

Abstract

Trial manufacture of POV and TBA test papers for detecting lipid oxidation was attempted. One drop of oxidized oil is placed on the POV test paper and let stand for one min. Then the paper is put into water, and blue color appears depending on the oxidation degree. On the TBA test paper, one drop of oxidized oil and three drops of water are placed. The paper is heated under infrared lamp for 5 min, and pink color is developed.
