Fabrication and characterization of carrageenan-based green materials

Abstract The chemical structure and ability to fine-tune its properties have made polysaccharide based composites a very attractive biomaterial. Polysaccharides are copious in nature and have good processability and hence have become one of the most commonly used biomaterial compared with other synthetic biomaterials. The biggest advantage of using polysaccharides in green composites is their environmental friendly nature. Among the different types of polysaccharides, carrageenan a sulfated polysaccharide extracted from red algae has recently received much attention. The applications of carrageenan-based materials include as gelling, stabilizing, and thickening agents in areas like food products. These materials have recently been explored in industrial applications, cosmetics, pharmaceutical applications, etc. Carrageenan-based materials are favorable alternative to fossil fuel-based polymers and are highly regarded as probable renewable and sustainable composite materials.
