Cane Sugar Refining with Ion Exchange Resins

Cane Sugar Refining with Ion Exchange Resins
Sucrose is extracted from the sugar cane stalk in a cane sugar Mill, purified and crystallized into a tan colored raw sugar. The sugar we consume must be further refined so as to not impart color, flavor or odor to the foods and beverages it sweetens. In a cane sugar Refinery the raw sugar is remelted and the sucrose is further decolorized with ion exchange resins, carbon or bone char and crystallized into white sugar for industry, consumers and confectioners. Although the ion exchange resins are used in the refinery, it is
