THE SEPARATION OF SYNTHETIC MIXTURES OF GLUCOSE AND FRUCTOSE AND ALSO INVERTED SUCROSE FEEDSTOCKS USING COUNTERCURRENT CHROMATOGRAPHIC TECHNIQUES

A pilot scale semicontinuous countercurrent chromatographic Refiner (SCCR4) unit packed with a Zerolit 225 resin in the Ca2+ form was used to separate synthetic mixtures of glucose and fructose and also inverted sucrose feedstocks into glucose-rich and fructose-rich products. For the same process conditions less pure fructose-rich products were found when using inverted sucrose feedstocks than with synthetic mixtures of glucose and fructose. However, anion-exchange resins Duolite A113 in the (HSO3-) form did not produce any variation in product purities with change of feed source.
