Exploratory data of the microalgae compounds for food purposes

Abstract

This brief data article refers to the previous exploration of Scenedesmus obliquus and Phormidium autumnale biomass about the possibility of using these microalgae species as an unconventional functional food. Data on chemical composition, fatty acids, volatile compounds, and carotenoid profiles were determined. In parallel, are provided the antioxidant capacity (reducing capacity - RC and reactive oxygen species deactivation - ORAC) of aqueous, lipophilic, and carotenoid extracts isolated from microalgae biomass. Both species have similar compounds in their biomass. However, S. obliquus was statistically different with a lower saturated fatty acid (STF) followed by higher mono (MUFA) and polyunsaturated (PUFA) content, also showed higher antioxidant potential for acetone extract and isolated carotenoids. On the other hand, P. autumnale aqueous extract showed high RC and ORAC. The significance of the experimental data was determined using the t-test (p < 0.05) based on the Statistica 7.0 software. These findings led us to explore the microalgae S. obliquus in an in vivo experimental model. Keywords: Microalgae, Carotenoid, Fatty acid, Antioxidant capacity, Compounds bioactive
