On the relations between morphological and structural modifications in sucrose crystals grown in the presence of tailor-made additives: effects of mono- and oligosaccharides

A survey is given on morphological modifications induced on sucrose crystals by some tailor-made additives (mono- and oligosaccharides). Special attention is paid to a critical discussion of our analysis of the structure compatibility between additive molecules and surface sites of the crystals, and further of its developments concerning incorporation of additives in the crystal lattice. Finally, it is shown as X-ray powder diagrams of sucrose crystals grown in the presence of these additives, coupled with chromatographic analysis of crystal sectors, proved to be a promising sensitive tool, chiefly to associate the different lattice spacing variations to the absorption anisotropy.
