Caracterización de productos co-cristalizados de sacarosa mediante Rayos X y DSC

Abstract

The objective of the work was to characterize through X-rays, differential scanning calorimetry (DSC) and scanning electron microscopy (SEM), co-crystallized products within a sucrose matrix. These products contained mineral salts, ca1ciumlactate, magnesium suIphate and a lyophilized yerba mate extract (Ilex paraguariensis). The studied techniques allowed comparing the structure ofthe different products and the hydration state of the salts after the process. The co-crystallized products showed the basic crystalline structure of control sample of sucrose. In the case of the minerals, dehydration was not totally accomplished since different salt hydrate structures were detected.
