Malic and citric acids were measured in orange and grapefruit juices by h.p.l.c. using a neutral resin column. Low levels of succinic acid (<0.01%) present in some samples required the use of a propylamine column, which was also used for succinic and malic acids in sweet cherry juice. All samples required preliminary separation on ion exchange columns to remove interfering substances. Either refractive index or ultraviolet (206 nm) detectors can be used for analyses after purification.
