Extracellular polymeric substances (EPS) are the biopolymers that naturally produced and secreted by wide species of microorganism. EPS are composed of protein, nucleic acid, lipid, and other bioactive molecules, but the main composition is polysaccharides. The EPS chemical composition and physical properties are different between species that influence their functional properties. The microbial EPS are utilized in various application such as wastewater treatment, cosmetic, pharmaceutical, and food industry mostly as flocculant, thickener, and emulsifier. This paper outlined the microbial EPS, especially their unique properties and application in the food industry. Moreover, we discussed the potential application of microbial EPS as edible coating.
