Microbial exopolysaccharides as a sustainable food ingredient and their health benefits

Many studies focus on regulating gut microbiota dysbiosis using beneficial bacteria, and postbiotics, particularly microbial exopolysaccharides (EPSs), are notable for their stability and potential in functional foods. EPSs are valued for their diverse structural properties and significant health benefits, especially for gut health. They are utilized as applications across various industries, including food, pharmaceuticals, biomedicine, and environmental management. However, the commercialization of EPSs requires extensive research into factors such as stability in different environments, interactions with biological fluids and enzymes, degradation profiles, and effects within living systems. This review provides an overview of different types of EPSs among postbiotics, highlighting their health benefits and discussing the considerations and limitations associated with their commercialization. Overall, the potential of microbial EPSs as functional food ingredients presents a promising opportunity for enhancing gut health and overall well-being.
