Arthrospira platensis is a promising and sustainable microalga characterized by easy growth without the need for herbicide or pesticide usage, and the possibility to utilize the whole microalgae without waste and harmful greenhouse gas emissions. It represents a valuable source of bioactive compounds with different health-promoting properties which make A. platensis an attractive ingredient for the formulation of eco-friendly cosmetics. As dehydration is one of the crucial production steps in the cosmetic, pharmaceutic, and food industries, the aim of this work was to investigate the influence of different drying temperatures on the chemical composition of A. platensis. Antioxidant activity of methanol: dichloromethane (1:1) extracts from differently dried (40, 50, 60, 80, and 100°C) samples were analyzed using 2, 2-diphenyl-1-picryl-hydrazyl (DPPH), reduction of the radical cation (ABTS), ferric reducing antioxidant power (FRAP) and oxygen radical absorbance capacity (ORAC) assays. The influence of drying temperature on total protein, carbohydrate, pigment, and lipid content was evaluated, while gas chromatography was carried out to determine fatty acid composition. By implementing ABTS and DPPH methods, the highest antioxidant activity was observed for the sample dried at 40°C followed by 50 and 80°C dried samples with 1.5- and 2.5-fold lower activity (p |
