Principle of Assay
Soluble sugars refer to the reducing monosaccharides in the sample, such as sucrose and maltose, that can be hydrolyzed into reducing monosaccharides under the determination conditions of this method, and starch that can be partially hydrolyzed into glucose. The detection principle is anthrone colorimetry. It can be used for the determination of soluble monosaccharides, oligosaccharides and polysaccharides. It has the advantages of high sensitivity, simplicity and speed, and is suitable for the determination of trace samples.
