A process employing extrusion was used to produce multicore microcapsules composed of multiple beads. The inner beads were made from ?-carrageenan (?-c), a thermo-responsive linear sulphated polymer whose gelling temperature ranges at 40-60 °C, depending on the concentration of ?-c polymer and the amount of potassium chloride used for gelation. The result ...
