Applications of marine polysaccharides in biomedical field and food industry

Marine polysaccharides exhibit a broad spectrum of structural variations and are presently not completely utilized. Numerous marine organisms serve as valuable sources of sulfated polysaccharides, possessing biological traits similar to glycosaminoglycans (GAGs). These polysaccharides from marine origins often demonstrate biocompatibility, indicating their well-tolerated nature within the human body. Consequently, they prove suitable for diverse biomedical applications, avoiding adverse reactions or immune responses. This chapter extensively explores the biomedical and food industrial uses of polysaccharides derived from marine microalgae, including chitosan and carrageenan. The examination encompasses their application in drug delivery, tissue engineering, wound healing, anticancer interventions, and the food industry. Ultimately, the concluding section highlights the noteworthy scientific and industrial potential of marine polysaccharides, which has garnered increased attention.
