Özet

This study investigated the feasibility of incorporating microalgae powders into model hard candies and evaluated their effects on physicochemical, structural, and functional properties. Microalgae species including Chlorella vulgaris, Spirulina platensis, Dictyosphaerium sp., and Pectinodesmus sp. were incorporated into candy formulations. Scanning electron microscopy revealed a semi-smooth candy surface with algal particles embedded within the amorphous sugar matrix. Time-domain nuclear magnetic resonance and hardness analysis indicated reduced crystallization in algae-enriched candies. Fourier-transform infrared spectroscopy identified characteristic polysaccharide bands along with amide and protein-associated functional groups derived from algal biomass. Biochemical analyses confirmed the presence of antioxidant activity, phenolic compounds, and flavonoids. Shelf-life evaluation demonstrated the retention of structural and textural stability over three months of storage. Microalgae incorporation influenced candy color, crystalline structure, moisture content, and nutritional composition while enhancing antioxidant functionality. This study provides a basis for the development of microalgae-fortified functional confectionery products.
