An HPLC tool for process monitoring: rare sugar D- psicose and D- fructose contents during the production through an enzymatic path

D-Psicose/allulose, a rare sugar, is an essential raw material in the pharmaceutical and food industries. It is scantly found in nature and to meet its demand in industries, D-Psicose is generated enzymatically using D-fructose as a substrate. In these conversations, it is important to monitor D-Psicose, in order to control the process, impurities, optimize the reaction time and reduce the process cost The available analytical methods have their...
