a more pronounced sugar-water volume creation of WBE-AXOS
compared to sucrose, could be explained by viscosity effects.
Indeed, the relative viscosity of a 5.0 g/100 ml WBE-AXOS solution
(hrel ¼ 1.58) was higher than that of a comparable sucrose solution
(hrel ¼ 1.10). Thus, AXOS is likely to increase the viscosity of the
sugar-water phase and thereby lower the dough spread (from
0.450 0.040 for control dough to 0.370 0.020 cm/min for dough with 30 g/100 g of the sucrose substituted by WBE-AXOS).
