Glucosamine is an amino sugar in which one of the hydroxy groups of glucose is replaced with an amino group, and is often used in health foods. At the 10th Edition Food Additive Official Formulation Study Group (3rd), a draft ingredient standard using liquid chromatography as a quantification method for glucosamine was decided. This time, we would like to introduce the analysis of glucosamine that complies with the draft component standard using the Hitachi HPLC system Chromaster.
