着色度と原料脂肪皮に添加したHemoglobin量との関係

抄録

The author studied the relation betwen the coloration of whale oil and the amount of hemoglobin added to raw blubber. The results obtained were as follows:
(1) At the preparation of whale oil, he ob ?? ed that the contens of pyrrole ring, nitrogen, and iron in oil were increased when hemoglobin was added to raw blubber previously.
(2) The color of whale oil is largely due to the natural hemoglobin that is contained in blubber.
Looking at the fact that, the more conspicuously the color of aqueous layer on boiling raw blubber becomes, the more intensely colored the oil layer becomes, he recommends to separate the two layer from one another as quickly as possible.
