[Analysis of vitamin C in the biologically active supplements to food and food products enriched with micronutrients].
Peculiarities in Vitamin C analysis of biologically active supplements to food and food products enriched with micronutrients are discussed. Visual titration method and spectrophotometric determination based on the utilization of sodium 2,6-dichlorophenolindophenolate are shown to be the most favourable oner. A special attention is paid to the nature of extragents used and protection against undesirable effect of some food components.
