The Applications in Pharmaceutical Industry 

Gellan gum can be used to produce easy-to-swallow solid dosage forms, such as gels and coated tablets, and to modify the rate of release of active ingredients from tablets and capsules. Gellan gum is also conveniently used for controlled or sustained release of various drugs and also for micro-encapsulation preparation. The bioavailability of theophilline from the gellan gels increases 4-5 folds in rats and 3 folds in rabbits compared to a commercial sustained release liquid dosage form.

Adhesion systems

Use of the gellan gum enables easy preparation of fat-free adhesion system. If the gellan gum solution is sprayed on various foods, such as the cracker, cookie, pretzel, potato chip, and rice cake, and then various seasoning flavors and other materials required for adhesion are sprinkled, a product with greatly reduced fat concentration can be manufactured.
