Encapsulation by using dripping – extrusion (D) methodParticles were produced using Encapsulator equipment (Büchi B-390). The cross-linking solution was CaCl2 3 g/100 g. The variablesconsidered were: nozzle diameter of 300 μm, air pressure of 200 mbar,vibration frequency of 100 Hz, and electrode tension of 400 V.
