Starch digestibility of bread was determined from dried samples, following the method previously described (Dura, Blaszczak, & Rosell, 2014) with minor modifications. Briefly, for free sugars removal, powdered sample (0.1 g) suspended in 2 ml of 80% ethanol was kept in a shaking water bath at 85 C for 5 min, and then centrifuged for 10 min at 1000g.
