SERIES OF CAPSULES COMPRISING AT LEAST ONE DROP OF INTERNAL PHASE IN A DROP OF INTERMEDIATE PHASE AND ASSOCIATED PRODUCTION PROCESS

摘要

Series of capsules comprising at least one drop of internal phase in a drop of intermediate phase and associated production process. Each capsule comprises a liquid core (14) and a gelled shell (16) comprising a gelled polyelectrolyte completely encapsulating the liquid core (14) at the periphery thereof. The gelled shell (16) is suitable for retaining the liquid core (14) when the capsule (12) is immersed in a gas. The liquid core (14) comprises an intermediate drop (18) of an intermediate phase, the intermediate phase being placed in contact with the gelled shell (16), and at least one internal drop (20) of an internal phase placed in the intermediate drop (18). The ratio of the volume of the core (14) to the volume of the gelled shell (16) is greater than 2, advantageously is greater than 50.
