抄録

To establish a standard color detection method, various color reactions for detection of kapok and cottonseed oil present in other oils were examined.<BR>Good detection was possible by the Halphen reaction and satisfactory results were also obtained by Besson, Milliau, and Becchi & Milliau reactions using silver nitrate.<BR>About 0.01% crude kapok oil or 0.1% neutralized cottonseed oil in soybean oil could be detected by the Halphen reaction. By the three reactions using silver nitrate, it was possible to detect nearly 0.5% crude kapok oil or 5% neutralized cottonseed oil.<BR>These results indicate that the Halphen reaction is the best method for color detection because of its high sensitivity, while the Besson reaction rates second in view of the simplicity of the procedure.
