Abstract

In this dissertation crystallization and microencapsulation processes are used to produce multicomponent particulate products with different functionalities (improved stability, controlled release, protection from environment, etc.) and their performance is assessed. Additionally, the interactions between the components in the processes are addressed. In this context, we investigated the crystallization in multicomponent mixtures, such as co-crystallization and anti-solvent crystallization. We employed electrospray crystallization as a technique for producing multicomponent (sub-)micron sized crystals. Additionally, wheat gluten were encapsulated in a matrix of hydrogel by a dripping method to delay fibrilization in a novel meat analog production process and atomic layer deposition was performed in a fluidized bed on various compounds to protect them from moisture or reactive species in the environment. Model compounds from various industrial fields (e.g. food, pharmaceutical and energetic material industries) are used to illustrate the wide applicability of the tested processes.
