*5.2. Complex Coacervation*

Complex coacervation is an encapsulation method that links and forms two differently charged biopolymers in a solution with the appropriate pH value. The most commonly used biopolymers are gum Arabic, gelatine, carrageenan, chitosan, carboxymethyl cellulose, and pectin [116]. This technique is claimed to be suitable for application at high temperatures and humidity exposure [117,118].
