Indirect Competitive Chemiluminescent Enzyme Immunoassay Method for Determination of Dimethyl Phthalate in Soy Sauce and Liquor

An indirect competitive chemiluminescent enzyme immunoassay (icCLEIA) for determination of dimethyl phthalate (DMP) was developed with high accuracy and precision by using luminol as luminescent substrate. The icCLEIA method was successfully applied to detecting DMP residue in liquor and soy sauce samples with satisfactory results.
