What You Need to Know
The process relies on ionic or covalent crosslinking of biopolymers such as alginate, pectin, chitosan, gelatin, and carrageenan. Temperature, polymer concentration, and crosslinker levels dictate gel strength and encapsulation efficiency, while rapid cooling or heating induces phase transitions that lock the core material within the matrix.
