Produce in processing sugar, sugar cane juice contains a variety of polyphenols, such as flavonoids, phenolic acids, phenolic glucosides, and phenylpropanoids. These compounds are the main source of colorants, essentially considered impurities. Removal of these polyphenols is generally done by using bone char.

Octadecylsilyl-silicagel (ODS) is widely used in reverse phase chromatography as a strong adsorbent of polyphenols. ODS can be regenerated by using alcohol, which can easily be recovered by evaporation. Hence, if ODS is used as the decolorizer of sugarcane juice, no liquid wastes will be produced from the clarification system. The objective of this study was to decolorize sugarcane juice by removing polyphenols with ODS adsorption, then recover these important polyphenol compounds from all fractions of the sugarcane juices.
