Abstract (en)

[origin: WO9604406A1] Refined sugar is produced without using conventional refining processes. Clarification of melted raw cane sugar is obtained either by ultra-centrifugation of ultra-filtration, and removal of certain compounds responsible for adverse color quality and viscosity is effected through a set of packet columns filled with an absorbent for these compounds. After evaporation and crystallization, refined cane sugar is produced.
