Microencapsulation allows controlled release of the asset and is activated depending on the type of coverage. Can be:
a) Dependent on the temperature. For example, in bakery, the release of sorbic acid is achieved only after the heat treatment of the dough (baked).
b) Release based on solubility. For example, in confectionery, acid taste is achieved only when the active ingredient comes in contact with an aqueous base such as saliva.
The controlled release of the microencapsulated active can be:
– Immediate (once the necessary temperature or pH is reached, the active is released immediately)
– Sharp (several encapsulating shells allow the gradual release of the asset)
The guided fluid bed technology:
It allows the active to be microencapsulated to fly in a fluid bed, while the cover is deposited slightly on its surface.
Advantages of guided fluid bed technology:
The active to be microencapsulated flies in a guided fluid bed, while the coating is deposited slightly on its surface.
Thin and uniform layer.
Particles with a wide diameter range (from 100μm to 2nm)
Decrease in the amount of coating to be used (while other technologies require a minimum of 50% w / w of coating for good protection, Guided Fluid Bed technology requires only 5% w / w)
Microparticles with greater amount of active.
Optimum operation over a wide temperature range.
Variety of types of coatings (with release by temperature / with release in aqueous base)
Pre-mixing process not necessary.
Decrease in production costs.
