Effect of ethanol concentration in the extraction solvent on the phenolic contents and antioxidant activity of blueberry pomace ethanolic extracts from ultrasound-assisted extraction (40 °C/40 min). TPC, TFC, TAC: total phenolic, flavonoid and anthocyanin contents, respectively; DPPH, antioxidant activity by DPPH assay. Means (n = 3 replicates) ± SD. Different letters indicate significant effect (p ≤ 0.05).
