Figure 2.

Antioxidant capacity of pear pomace flour measured via FRAP and DPPH assays. The data shown are mean values (n = 3) followed by an alphabet letter (for comparison between the different granulometric fractions subject to a two-step extraction), an alphabet letter and apostrophe (for comparison between the different granulometric fractions subject to maceration) or a Greek letter (when comparing extraction methods). Different letters mean significantly different results (Tukey’s HSD; p ≤ 0.05).
