Application of In Situ Coating on a Two-Compound System

To test the application of in situ coating as an alternative coating technology, pastilles drop-formed from molten mixtures containing xylitol and isomalt were produced. The efficiency and usability of the classical nucleation techniques in this practical application could be demonstrated. Besides the influence of power ultrasound and seeding, the effect of a combination of both on nucleation at the shell of the drop-formed melt mixtures was examined. Microscopic cross-section pictures illustrate the impact on quality of the coating layer of drop-formed pastilles.
