Abstract
It is said that the food dye, Yellow AB or Yellow OB, contains often the impurity of the original dyestuff intermediate, namely β-naphthylamine which is potent carcinogen. These industrial food dyes manufactured in our country were examined and it was found that all the food dyes, yellow AB and Yellow OB, examined contained a small amount of β-naphthylamine.The main aromatic amines as the metabolits in the urine of experimental animals fed with these food dyes were aniline or o-toludine and its derivatives.It is desirable to cease the use of such food dye as Yellow AB or Yellow OB which contains carcinogenic intermediate even if its amount is a very little.
