The active compound for a micro-encapsulation could be a flavour-oil, for example. For cover-material, substances like gelatine, gum arabic, starch, maltodextrin or cellulose are available. The apparatus- and plant-configurations of NEUHAUS NEOTEC can be designed for top- and bottom-spray processes. Depending on the initial substance this offers you the advantage of always getting the requested final product and reproducible processes.
Targets of micro-encapsulation:
- Storage stability (protection against chemical reactions, oxygen, light, humidity)
- Fixation of volatile compounds
- Transformation of liquids into solid substances
- Depot effect (targeted and time-delayed release of active ingredients)
- Masking of taste or odour
- Stable separation of incompatible substances
- Enhancing of flowability
- Reduction of dust and electrostatic charge
Example of application: Protection of flavours
By micro-encapsulation, citrus aroma is embedded in a solid matrix and homogeneously distributed. The final product are dust-free, compact, light and oxidation-protected flavour granules with an ideal release profile.
Further applications:
Stabilisation and encapsulation of sensitive components, production of depot effects
