In the previous paper, the author reported that the color of whale oil is increased by the addition of hemin, also he had come to conclusion that the color of oil is caused by the splitting of porphyrin ring during the course of boiling of blubber. The author a ?? sumed that the splitting of porphyrin ring is not attributed to proteinoas matters, but it may be caused by peroxides which yielded in whole oil by atmospheric oxygen. In order to prove this assumption, the author carried out the experiments using whale oil which contained no proteinous matters. As shown in Table 1-6, the results of experiments were entirely identical as expected, i.e. the color of whale oil is related to the amounts of peroxides and, when oil contains many quantities of peroxides, the coloration of oil becomes higher than that of low peroxide value oils.
