Sucrose solubility in impure cane sugar solutions

There is a growing interest in the industry in on-line measurement and use of supersaturation in crystallization control. Its accurate determination, however, requires reliable data on the solubility of sucrose in impure suga r solutions. Extensive research has led to a well established method for ca lculating this solubility in beet sugar syrups, based on syrup quality para meters, However, there seems to be much less information available on sucro se solubility in cane sugar syrups. Based on data collected by Thieme (the only source of data on cane sugar syrups known to this author) this paper r eports attempts to determine the relevant quality parameters and extend the methodology, which proved its worth with beet syrups, to cane sugar soluti ons.
