The total phenolic contents (TPC) of the fibre concentrates obtained
from exotic fruit co-products are presented in Fig. 1. The
TPC of the fibre concentrates, expressed as gallic acid equivalent,
ranged (p < 0.05) from 129 mg/100 g for pineapple to 546 mg/
100 g for mango, in the methanol:acetone extractions. In the ethanol
extraction, TPC values were lower (p < 0.05) than those in the
