Chloride salts can serve as sodium chloride (NaCl) substitutes in wheat dough for sensory or technological reasons. Therefore, the effect of different substitutes on wheat dough development during mixing (optimum water absorption, dough development time, stability) and fermentation (maximum dough height) with a material-adapted water addition and mixing time were investigated. The substitutes had effects on all measures at a level of 2 g salt 100 g−1 wheat flour, with the exception of KCl. The intensity of the effect significantly followed the Hofmeister series due to an altered hydration behavior of the structure-determining gluten proteins. The experiments were supported by CLSM micrographs combined with image analysis. Next to an absolute substitution, the main focus of the study were concentration dependent functionalities of the chloride salts. Therefore, concentration dependent rate constants were calculated based on the application of different concentration levels of the chloride salts. These rate constants showed in all cases a similar tendency following the Hofmeister series.
