title: [Determination of vitamin C in selected fruit and vegetable products].
abstract: A simple method was described to determine vitamin C as L-ascorbic acid (after reduction of dehydroascorbic acid by means of dithiothreitol) in fruit juices, fruit and vegetable-fruit nectars. Ascorbic acid was analyzed by RP-HPLC technique with UV detection (254 nm). The average recovery of ascorbic acid was 92-103% and limits of identification and detection were 0.003 and 0.009 mg/ml of products respectively.
