Abstract
The aim of the present work is to study the way in which defense glycoproteins, produced by sugar cane plants, retard and modify the crystallization pattern of sucrose. The effect of defense glycoproteins against smut on the crystallization of sucrose has been studied with preference. In general, these glycoproteins delay the appearance of the first nuclei, hinder the association of individual crystals to form agglomerates or star-like nuclei, and increase the degree of surface erosion of the formed crystals. Using defense glycoproteins labeled with fluorescein isothiocyanate, it has been observed that the adhesion of these glycoproteins to the sucrose crystals is carried out mainly on the edges thereof, never on their flat faces, and never penetrates inside them, although they may move along its outer surface. The fluorescence diffuses in the zones of rupture or abrasion, indicating that the appearance of such accidents releases the proteins adhered to the free solution.
