Rhamnose is 6-deoxy-L-pyranomannose obtained from the quercetin-producing hydrolysate through recovery and extraction. As a rare monosaccharide that exists in nature, rhamnose can be used to determine the permeability of the intestinal tract, can be used as a sweetener, and can also be used to synthesize glycosides of cardiac drugs and spices.


Rhamnose is a methyl pentose sugar and has properly been classified as one of the rarer sugars. This sugar is a constituent of many glycosides. The rhamnoglycoside of quercetin (rutin) has been most often used as a source of rhamnose and after its hydrolisis, it yields the aglycon and L-Rhamnose. Rhamnose obtained by this method is a very pure crystalline powder, free from any visible impurities. Rhamnose finds use in the flavor industry as a starting material for the production of furanones, as well as the starting raw material in reaction flavors developed during the preparation of various foods such as bread, grilled meats, etc. L-rhamnose is a natural sugar found in several animal, plant and bacterial polysaccharides. Commercially available rhamnose is produced by of arabic, karaya gums, or from sophora japonica rutin or citrus fruits which contain rhamnose.
