Development of Bread with NaCl Reduction and Calcium Fortification: study of Its Quality Characteristics

The impact of NaCl reduction and replacement by CaCl2 : CaCO3 (50:50) on dough and bread characteristics is addressed in this study. Three recipes of white bread were formulated with different percentage of NaCl substitution; all doughs had 1.8 g of total salts added per 100 g flour weight basis. Comparison was performed against control bread containing 1.8 g of NaCl per 100 g flour weight basis. Alveograph and farinograph results indicated that addition of calcium decreased dough extensibility, stretchability and stability time, keeping strong flour characteristics. Calcium salts increased hardness of upper crust and decreased hardness of lower crust. An increase of calcium salts promoted lighter crumb and crust color. Descriptive sensory analysis indicated that 16 out of 25 traits showed significant differences between control and recipes. Principal component analysis using variables such as texture, color and sensory traits indicated that breads produced with 50% NaCl substitution were comparable with the control.Fil: Bassett, Maria Natalia.
