Abstract:
1. A process of producing a sugar composition comprising a definite amount of a target hexose, wherein the target hexose comprises D-psicose in a range of 5 to 10 wt % and D-allose in a range 1.5 to 5 wt %, comprising: i) preparing a starting liquid sugar material as an alkaline solution at 0.005 to 0.1 M alkali, the staring liquid sugar material being an isomerized sugar syrup containing D-glucose and D-fructose as the main components, and then, ii) isomerizing the alkaline solution via treatment at a temperature between 40° C. and 70° C. in the presence of at least a basic ion exchange resin, and thus performing an isomerization reaction which is an equilibrium reaction for transforming the starting sugar material into the target hexose, wherein the concentration of the hexose in the starting liquid sugar material is 5.0 w/v % to 40.0 w/v %.
