Abstract
Gamma cyclodextrin is separated and purified by a process that first precipitates the gamma cyclodextrin from solution using a gamma cyclodextrin complexant followed by a step of removing the complexant from the precipitate and then passing the resulting solution containing the gamma cyclodextrin through a chromatographic material from which the gamma cyclodextrin is eluted.
