Instant Controlled Pressure Drop Used in Oligosaccharide Analysis

December 15, 2008

A research group from LMTAI (La Rochelle, France) and LVMH Recherche (St. Jean de Braye Cedex, France) analyzed the oligosaccharides ciceritol and stachyose extracted from Tephrosia purpurea seeds using an instant controlled pressure drop pretreatment before solvent extraction.

A research group from LMTAI (La Rochelle, France) and LVMH Recherche (St. Jean de Braye Cedex, France) analyzed the oligosaccharides ciceritol and stachyose extracted from Tephrosia purpurea seeds using an instant controlled pressure drop pretreatment before solvent extraction. They investigated parameters such as steam pressure, initial water content, and thermal treatment time. The pressure drop step reportedly enabled increased diffusion of solvent inside the seeds. The researchers verified the procedure’s structure modification in the seeds using scanning electron microscopy micrographs.
