Antioxidant activities and phenolic compounds of raw and cooked Brazilian pinhão (Araucaria angustifolia) seeds

  In this study, the antioxidant properties and the polyphenolic contents of raw and cooked pinhão seeds were evaluated. Four methods were used to evaluate the antioxidant activity: 1,1-diphenyl-2-picrylhydrazyl free radical scavenging (DPPH), 2,2’-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid scavenging (ABTS), ferrous ions chelating activity and lipid peroxidation inhibition (LPO). The...
