Abstract
A method for detecting reducing sugars in samples using a test reagent containing an indicator capable of producing calorimetric changes when contacted with reducing sugars. Under alkaline conditions, reducing sugars present in a sample affect a reduction of the indicator to a colorless or differently colored reduced form. The method may include the additional step of pretreating the sample with a glycosidase to convert non-reducing sugars to reducing sugars.
