Coacervation is a unique and promising microencapsulation technology because of the very high payloads achievable (up to 99%) and the controlled release possibilities based on mechanical stress, temperature or sustained release. Coacervation is typically used to encapsulate flavor oils, but can also be adapted for the encapsulation of fish oils nutrients, vitamins, preservatives, enzymes, etc.
The basic physical and polymer chemistry behind the coacervation process is well developed and understood. The concept behind (simple or complex) coacervation microencapsulation is the phase separation of one or many hydrocolloids from the initial solution and the subsenquent deposition of the newly formed coacervate phase around the active ingredient suspended or emulsified in the same reaction media. The hydrocolloid shell can then be crosslinked using an appropriate chemical or enzymatic crosslinker, if needed. A very large number of hydrocolloid systems has been evaluated for coacervation microencapsulation but the most studied and well understood coacervation system is probably the gelatine/gum acacia system
