Gum karaya is a polysaccharide that has several industrial applications in the pharmaceutical, food, and environmental fields owing to its hydrophilic, anionic, and biocompatible nature. Gum karaya and its modified forms have been assessed for drug delivery, wastewater treatment, and food industry applications. This review provides a comprehensive overview of various synthetic methods of modification of gum karaya, such as grafting initiated through free radical, microwave-assisted grafting, radiation-assisted, and enzyme-assisted modification methods. In addition, the review outlines collective industrial applications of modified gum karaya in drug delivery systems, removal of heavy atoms, dyes, food, and other biological activities, and suggests possible prospects for gum karaya modification and their remarkable industrial applications.
