2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) assays, concentration of samples to scavenge the ABTS+ of 50% (EC50) and Trolox Equivalent Antioxidant Capacity (TEAC) values. EC50 values (μg/mL) with confidence limits (95%, in brackets) and TEAC values (EC50 Trolox/EC50 Sample) of hydroalcoholic extracts of Indonesian cocoa beans (ICB) and Peruvian cocoa beans (PCB) samples in DPPH and ABTS assays. Trolox was used as standard.
