Determination of retinyl palmitate (vitamin A) in fortified fluid milk by liquid chromatography: collaborative study



Determination of retinyl palmitate (vitamin A) in fortified fluid milk by liquid chromatography: collaborative study



Journal of Aoac International 86(2): 375-385



A liquid chromatographic (LC) method was developed for fast and simple measurement of retinyl palmitate (vitamin A) in fortified milk. Retinyl acetate internal standard was added to a test portion of milk followed by extraction into hexane. The hexane extract was analyzed by LC using a normal-phase silica gel column equilibrated with mobile phase (conditioned hexane-isopropanol, 99.85+0.15, v/v) about 1 h before injections.
