Extraction, Characterization, Biological Properties, and X-Ray Fluorescence Analysis of Functional Polysaccharides...

This study explored the extraction, characterization, and biological properties of polysaccharides derived from Spirulina (Limnospira platensis), a microalga known for its rich nutritional benefits. Polysaccharides were successfully isolated and characterized using optimized biorefinery water extraction techniques to detail their structural and functional characteristics. Results revealed notable antioxidant activity and effective α-glucosidase inhibition, indicating potential health benefits. X-ray fluorescence (XRF) analysis was conducted to assess the elemental composition, offering insights into the mineral contents of the polysaccharides. Our findings underscore the promising applications of polysaccharides from Limnospira platensis as functional ingredients in health-related fields, advocating the need for further research into their mechanisms of action and therapeutic applications.
