%0 Journal Article %T ASSAY OF ASCORBIC ACID BY RP-HPLC IN SAMPLES CONTAINING ALSO CITRIC ACID %A V. Ostafe %A C. Brumaru %A Gabriela Papoe %A Ioana Lupsa %J Annals of West University of Timi£¿oara : Series of Biology %D 1999 %I West University of Timisoara %X The ascorbic acid is widely used as antioxidant in food products. As this substance is a very unstable substance, its concentration needs an accurate monitorization. A RP-HPLC method was used for identification and quantification of ascorbic acid in mixtures used in sausage industry. Reliable results are obtained even the samples contain high quantities of citric acid. The regression coefficient of standard curve is 0.999. %U http://www.biologie.uvt.ro/annals/vol_2/AWUTSerBio_Dec1999_95to104.pdf
