An evaluation of the antioxidant properties of Arthrospira maxima extracts obtained using non-conventional techniques (original) (raw)

2016, European Food Research and Technology

The best results were obtained under MAE at 90 °C for 10 min with the highest yields in terms of total carotenoids and β-carotene (>2.6 and >1.0 mg/g algae, respectively). MAE with ethanol (90 °C, 30 min) allowed maximization of total carotenoids and β-carotene amount (3.12 and 1.37 mg/g algae, respectively) thanks to the very good extraction yields. Moreover, this technique gave an extract with the highest antioxidant activity (812 and 519 µmol Trolox/g extract for TEAC and ORAC, respectively). Surprisingly, polyphenols were not detected in A. maxima extracts analyzed by HPLC.
