What test can detect all monosaccharides and disaccharides?

The Benedict's test can detect all monosaccharides and some disaccharides, such as maltose and lactose. This test involves adding Benedict's reagent to a sample and heating it; a color change indicates the presence of reducing sugars. However, non-reducing disaccharides like sucrose do not react with this test unless they are hydrolyzed into their monosaccharide components. For a broader analysis, more specific tests or chromatography methods may be needed to identify all sugars present.
