%X Spirulina and Bilberry are underexplored and underutilized in the food industry. Therefore, this research focuses on determining the antioxidative properties of Spirulina and Bilberry for future use in functional food product development. The objective was to determine the Total Phenolic Content (TPC) and Total Flavonoid Content (TFC) in Spirulina and Bilberry extracts (Aqueous and Ethanol extracts) and their antioxidative potential (2,2-diphenyl-1-picrylhydrazyl (DPPH), Ferric Reducing Antioxidant Potential (FRAP), Trolox Equivalent Antioxidant Capacity (TEAC), and Nitric Oxide Radical Scavenging Ability (NORS)). Spirulina and Bilberry pure and combination samples [100% Spirulina (100S), 100% Bilberry (100B), 50% Spirulina + 50% Bilberry (50S + 50B), 75% Spirulina + 25% Bilberry (75S + 25B), & 25% Spirulina + 75% Bilberry (25S + 75B)], were extracted with aqueous (deionized water) and 80% ethanol solutions. Colorimetric antioxidant assays were used to determine total phenolics, total flavonoids, and their antioxidant potential. 80% ethanol Spirulina and Bilberry (pure and combination) extracts resulted in higher TFC, FRAP, and DPPH, whereas aqueous extracts had higher TPC, NORS, and TEAC, suggesting both hydrophilic and lipophilic bioactive compounds in Spirulina and Bilberry. Spirulina and Bilberry are two potential functional food ingredients for the food industry due to their antioxidative properties.
