AVEKA has a number of microencapsulation techniques and technologies that can be applied to a range of materials. Our broad scientific and engineering expertise gives us the ability to investigate and tailor the microencapsulation approaches to meet your needs.

The choice of microencapsulation approach is determined by several key factors, including:

The material to be encapsulated: is it solid or liquid, water soluble or hydrophobic?
How is the encapsulated material to be released from the microcapsules when needed--by dissolution of the capsule walls, mechanical breakage, melting, or digestion processes?
What kind of controlled release is desired--gradual, sudden, or tied to a pH, temperature, or other physical/chemical change?
What is the desired size range of the particles?
What is the desired capsule loading (i.e., the ratio of fill or core material to shell)?
Is the microencapsulated product intended for human consumption (foods, flavors, nutritional supplements, or pharmaceuticals) or for use in animal feeds?
What are the quantities and price targets for the material?
AVEKA's microencapsulation technologies include alginate beads, PMU beads, water beads and complex coacervation as well as the use of spray drying and prilling to encapsulate materials. These techniques are described below with details located on other pages.
