Nowadays, the dietary sodium chloride intake is higher than the daily recommended levels, especially due to its prominent presence in food products. This may cause an increase of high blood pressure leading to cardiovascular diseases. Cereal products, and in particular bread, are the main source of salt in human diet. However, salt is a critical ingredient in bread making, and its reduction can have a negative impact on bread quality.

Function of Sodium Chloride in bread:

In general, the functions of salt in bread are summarized as:

• Sensory effect by imparting flavor 

• Control of yeast growth and fermentation rate 

• Improvement of product texture 

• Reduction of spoilage, particularly mould spoilage.

The main technological effects of salt on the process of bread baking are summarized as:

• The development of gluten-structures in the mixing of
  dough is promoted. 

• Yeast activity is inhibited during the fermentation step,
  which results in a lower gas release. 

• Water activity is controlled in the baked products. 

• Formation of a fine elastic crumb during baking

A level of +/- 2% Sodium Chloride is quite the optimum for the bakery process. 


• Potassium Chloride: The replacement of salt with potassium chloride does not result in any significant production disadvantages but has an adverse impact on the flavor of bread once the substitution level rises above 30% of sodium chloride

• Replacement of sodium containing ingredients (e. g. Sodiumbicarbonate, Sodiumcarbonate or Sodiumacetate) with the corresponding potassium minerals (e. g. Potassiumbicarbonate, Potassiumcarbonate or Potassiumacetate)

•  Mineral Salts (K/Mg/Ca): breads prepared with this solution were found to be comparable to regular bread with respect to flavor and texture. No negative effect has been reported even at lower salt levels.
