• 論文の詳細を見る

• A simple method has been devised to remove the pigments, yellow AB and OB, from the unsaponifiable fraction of margarine by treating the petroleum ether phase with glacial acetic acid containing a small amount of acetaldehyde. Applying this method, the vitamin A in the margarine containing no carotenoids can be determined easily and accurately. The recovery of vitamin A throughout the whole procedure was found to be above 96 per cent.
