<strong>Cane</strong> <strong>Sugar</strong> <strong>Refining</strong> with Ion Exchange Resins<br />
Colorants<br />
The sugar colorants are a very complex mixture of organic compounds from various<br />
sources. They can be categorized into two main types, natural colorants resulting from<br />
the cane plant and those developed during the juice processing. The main characteristics<br />
of the colorant to be removed are that they are mainly hydrophobic (non-polar) and<br />
they cover a large range of molecular weights (Table 1). They exhibit anionic behavior.<br />
