High performance liquid chromatographic determination of sorbic acid in wine. 1977

M A McCalla, and F G Mark, and W H Kipp

A method is described for the qualitative and quantitative determination of 2,4-hexadienoic acid (sorbic acid) by high performance liquid chromatography (HPLC). The results show excellent reproducibility (+/- 2.55%) and agree well with values obtained using the official AOAC ultraviolet method for both fortified wine and commercial wines. Sorbic acid is separated by HPLC, using a strong anion exchange resin, Zipax SAX, eluted with 0.01M Na2B4O7, and detected using UV (254 nm) detector. Sodium benzoate is used as an internal standard.
