  1. a, b, c, d, e Values with the same superscript letters in the same line are non-significant at p < 0.05; Total phenolics are expressed as mg gallic acid equivalents (GAE)/100 g of bread; DPPH• radical-scavenging and metal (Fe2+) chelating activities are presented as IC50 values (mg/ml); Fe3+ reducing power (A700, absorbance at 700 nm) is determined at 2 mg/ml of bread extract
