This proposal specifies a method for the determination of sorbic acid in meat, fish and their products by liquid chromatography. It is applicable to livestock meat, poultry meat, fish and other meat products. In this standard, samples are extracted by water, high-fat samples are degreased by n-hexane and high-protein samples are precipitated by adding protein precipitant. After that, samples are separated by liquid chromatography, detected by PDA detector, and quantified by external standard method.
