A quantitative method for the direct LC/UV determination of octenylsuccinic acid (OSAc) in nutritional products formulated with octenylsuccinic anhydride-modified starch (MS) is described. The cis-2-OSAc and trans-2-OSAc released from the MS by a mild alkaline hydrolysis are separated by reversed phase chromatography and are detected by UV at 192?nm. Method suitability has been defined by assessments of linearity (R 2 average--.99991?±-.00008, n--2, and the relative calibration error average
