The separation of synthetic mixtures of glucose and fructose and also inverted sucrose feedstocks using countercurrent chromatographic techniques
- 76 Downloads
A pilot scale semi-continuous countercurrent chromatographic Refiner (SCCR4) unit packed with a Zerolit 225 resin in the Ca2+ form has been 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 (HSO 3 − ) form did not produce any variation in product purities with change of feed source.
