ABSTRACT:
The present invention relates to a novel presentation of a product exhibiting the phenomenon of supercooling. More precisely, the subject of the invention is cristallized pearls of a product exhibiting strong supercooling. The invention also relates to the preparation of the said pearls. The characteristic feature of the process of the invention is to melt, if necessary, the product to be shaped; to break up the molten mass into droplets; to cool the droplets to a temperature below the glass transition temperature of the product, so that these droplets harden by vitrification; to maintain the pearls thus vitrified at a temperature below the glass transition temperature and to place them in contact with crystallization seeds; to crystallize the pearls by raising the temperature above the glass transition temperature and then to recover the crystallized pearls.
