Abstract
In recent years, the whole world is increasingly interested toward plant-based natural polymers. Okra (Abelmoschus esculentus), commonly known as lady�s finger, belongs to Malvaceae family. It is an important agricultural crop which is widely cultivated throughout the tropical and subtropical regions, particularly in India. The fresh green pods of okra produce viscous, slimy mucilage, also called okra gum. Okra gum contains polysaccharides comprising of rhamnose, galactose, glucose, galacturonic acid, and glucuronic acid. Many studies have highlighted its biodegradable, chemically inert, nontoxic, nonirritant, and eco-friendly nature. Based on the studies, this chapter mainly deals with the properties and potential applications of okra gum in food, pharmaceutical, and packaging industries. A small background is given on extraction and characterization of okra gum. The properties of okra gum are then elaborated and finally various applications of okra gum as a binder, fat replacer, thickening and coating agent are highlighted for its better utilization. � 2023 Elsevier Inc.
