Resumen:
Bread is the food most and widely consumed by people through the world. Traditionally is elaborated with wheat flour and sodium chloride is an important ingredient, because enhance flavor and strengths gluten in dough. Nevertheless, efforts of eliminating salt from diet and foods were performed. It is well known that salt (NaCl) has influence in the development of some diseases related to high blood arterial pressure. The average consumption of bread (2% salt) in Argentina is around 175 g/day per person, with an implicit salt intake of approximately 3.5 g/day per person. This intake is close to OMS-FAO recommendations (5 g salt/day per person). Breads without salt resulted whitish and insipid becoming less acceptable by consumers. The objective of this work was to replace the total content of sodium chloride of a French-type bread formulation by other potassium (K chloride and citrate) and calcium (Ca chloride, citrate and carbonate) salts; and to evaluate the effect of these salts in bread specific volume (Vsp) and texture and alveolus characteristics of crumb. The Vsp was not modified by the total replace of NaCl for calcium carbonate (CaCO3) and calcium citrate (CaCit); while this parameter increased and decreased with the presence of potassium citrate (KCit) and calcium chloride (CaCl2), respectively. With calcium salts a more opened crumb was obtained, with a low number of alveolus per area, alveolus with high average area and consequently a high fraction area occupied by alveolus. In spite of a similar alveolus distribution was obtained with calcium salts, CaCl2 generated softer, less cohesive and elastic crumbs, with lower chewiness than CaCO3 and CaCit. The softer crumbs with the lowest chewiness were obtained with KCit and KCl. Breads with the optimum crumb texture (CaCl2, KCit and KCl) were paradoxically those with the more bitter taste. Breads with quality similar to common bread (NaCl bread) were those formed with CaCO3 and CaCit. It can be concluded that from the point of view of physical quality, NaCl can be replaced by CaCO3 and CaCit in bread formulation, although the final acceptance of the product is conditioned by their sensory quality.
