[Use of high performance liquid chromatography for analysis of vitamin A in food products].
High-performance liquid chromatography (HPLC) was used for vitamin A assay in foods and raw materials. Metrological characteristics of this method have been estimated: relative standard deviation was 0.06-0.08, average recovery of vitamin A was 97.3 +/- 2.6 with n = 6, P = 0.95). The statistical analysis of the results obtained with HPLC has shown that it could be successfully used for vitamin A assay in varying foods containing no less than 0.01 mg of vitamin A per 100 g.
