2. Purification Process
Fructose and glucose are two isomers with the same molecular weight. Fructose is ketohexose while glucose is aldohexose. As Ca² resin can form a stable complex with fructose and adsorbs fructose in the adsorption agent (Ca² resin) of the adsorption column, while glucose will not form such a complex and will not be adsorbed (or its adsorption force is smaller than fructose), fructose in high fructose corn syrup has greater adsorption force in Ca² resin than glucose. Hence, under the action of the desorption agent, fructose retains long hours in resin while glucose retains shorter hours. Glucose will first desorb from the resin. In the continuous chromatographic separation system, fructose and glucose can thus be continuously separated.
