Natural mucilage extracted from chia seed (Salvia hispanica L.) exhibits specialized water gelatinous behaviour when formulated and manufactured along with other polysaccharides and agents to form a hydrogel capsule shell wall. This will enable the mucilage hydrogel containing capsule shell on exposure to water to expand to twice its size with consequent swelling of the polymeric network and slow release of a drug within the capsule shell for example omega-3 fatty acids obtained from chia oil. The polymeric network can degrade biologically. A process for the preparation of the extracted mucilage and a capsule comprising said mucilage are disclosed. A 100% vegetarian product is prepared where both the material to be delivered and hydrogel capsule shell are produced purely from vegetarian products, free from animal derived substances. |
