Less salt in bread: a major challenge for bakers

The demand for healthier eating is growing louder. Consumers want less salt, but for bakers, that is easier said than done. In the US, people consume an average of about 3,400 mg of sodium per day, while the guideline is 2,300 mg—or even 1,500 mg according to the American Heart Association. New dietary guidelines are on the horizon, but reducing salt in our food remains a significant task.

For bakers, less salt means not only a change in taste, but also in structure, texture, shelf life, and even food safety. Salt plays a crucial role in the baking process: it influences yeast activity, strengthens gluten, prevents over-fermentation, extends shelf life, and provides that attractive golden-brown crust.

What can bakers do?

• Gradual salt reduction (10–25%) to limit loss of flavor.
• Use of potassium chloride or enzymes as salt substitutes.
• Application of natural flavor enhancers and clean-label solutions.
• Communication to consumers regarding the health benefits.

Producing low-sodium tortillas is particularly technically complex due to the effect on gluten development and the leavening process. Gluten-free products also pose an additional challenge due to the sodium-rich ingredients already present.

Salt reduction therefore requires smart innovation as well as consumer awareness. Small adjustments in everyday products such as bread can make a big difference for public health.
