Metanil Yellow (Acid Yellow 36) is a dye of the azo class. In analytical chemistry, it is used as a pH indicator and it has a color change from red to yellow between pH 1.2 and 3.2. [1]
Although illegal for food use, Metanil Yellow has been used as an adulterant in turmeric and pigeon pea based food products, particularly in India. [2] [3] [4] [5]
Animal studies have suggested that Metanil Yellow is neurotoxic [3] and hepatotoxic. [6]
