AbstractA semi‐continuous counter current chromatographic refiner, developed in this department, was used to produce high fructose syrup from an industrial barley syrup containing 42% fructose, 52% glucose and 6% maltose and oligosaccharides. The chromatographic refiner consisted of twelve 5.4 cm i.d. columns, each packed to a height of 65.5 cm with KORELA VO7C calcium charged resin, with a particle size range 150–300 μm. At a throughput of 32.1 kg sugar solids/m3 resin/h, the fructose rich product obtained was 95% pure and had a concentration of 11.3% w/v, while the glucose rich product contained only 4.5% fructose and had a concentration of 22.56% w/v.
