Only approved food colors can be used and others, such as some azo compounds (otherwise known as "Sudan dyes"), are banned because of their potential carcinogenicity.
can bring about the reduction of azo compounds. Ogawa et al studied about the reduction of azo compounds and found that sodium sulphite reduces them to hydrazo derivatives and then gradually to amines, whereas Sn[Cl.sub.2] reduces azo compounds directly to amines [10].
