Abstract
Three automatic flow injection methods for the determination of reducing sugars in wine based on classical reactions (the picric acid method, the CuII-neocuproine method and the Nelson-Somogyi method) are proposed. Their usefulness was tested by applying them to white and red wines. The results obtained agree with those provided by a batch standard method. The standard additions procedure yielded recoveries above 94.2% in all instances.Keywords
