Alginate, a heteropolysaccharide extracted from brown algae Laminaria digitata, has non-toxic status and good physical and chemical properties, was used in this study for encapsulation of the cyanobacterium Arthrospira platensis. Results indicated that adding A. platensis to alginate beads increased the level of mineral elements: magnesium by 55–60 mg/kg, iron by 38–40 mg/kg, and iodine by 88–107 μg/kg, as compared to respective control samples without microalgae addition. Adding A. platensis within alginate beads resulted in an increased antioxidative potential and consequent higher inhibition of the radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) by 15–25% compared to the respective control alginate beads. Finally, the content of beta-carotene in alginate beads fortified with A. platensis biomass amounts on average to 51 μg/g. Due to their health-promoting potential, alginate beads enriched with A. platensis biomass can, therefore, be used as a functional ingredient in the nutraceutical sector.
