Technological characteristics of sodium reduced wheat bread: Effects of fermentation type and partial replacement of salt with potassium chloride

Abstract

Rheological, physicochemical, textural, and sensory characteristics of wheat bread prepared by potassium chloride (KCl) substitution of sodium chloride (NaCl) at different ratio (0:100, 10:90, 20:80, 30:70, 40:60, 50:50) in the presence of two different fermentation types (Saccharomyces cerevisiae yeast starter (YSF) and mixed fermentation based on sourdough (MFSD)) were investigated. Considering the results obtained at this study, the technological characteristics change through KCl substitution ratio which depends on the type of fermentation. In other words, the enhanced activity of microflora in MFSD-fermented samples and decreased activity of yeast in YSF-fermented ones have been found by increasing the ratio of KCl incorporation level. Despite the increased activity of starter microflora in MFSD-fermented samples through increasing the KCl incorporation level, the lowest specific volume (p <.00).
