[High performance liquid chromatographic analysis of organic acids in foods].

Because of the speed, selectivity, reliability, and simple sample preparation high performance liquid chromatography (HPLC) is the preferred method for simultaneous separation and determination of organic acids in foods. Ion exchange chromatography, ion exclusion chromtography and reversed phase HPLC are the most common chromatographic modes for analysis of organic acids in foods. The development and application of the three chromatographic modes are reviewed with 54 references. Ion exchange chromatography is most satisfactory for analysis of organic acids in foods, because organic acids are not interfered by other organic compounds, and inorganic anions in foods are determined simultaneously with organic acids.
