Bromate refers to potassium bromate, a flour improver sometimes added to white bread flour to strengthen dough and promote higher rising. It became popular in industrial baking for its ability to produce light, fluffy loaves quickly. However, growing scientific concern over its safety has led to major regulatory changes worldwide.
Health Concerns and Legislation
Research has linked potassium bromate to potential health risks, including carcinogenic effects. As a result, it is banned in the United Kingdom and throughout the European Union under Regulation (EC) No 1333/2008 on food additives. The additive is considered a possible human carcinogen by the International Agency for Research on Cancer (IARC), prompting strict regulation.
In contrast, bromate remains legal in some countries, including the United States, where it is still permitted for commercial baking, although some states and companies have phased it out voluntarily.
To ensure safety and compliance, all flour used at The Sourdough School is bromate-free. We advocate for transparent sourcing and the use of naturally fermented dough to develop strength and texture without chemical additives.
Bromate-Free Baking with Sourdough
When baking with botanical blend flours, there’s no need for synthetic enhancers like bromate. The natural strength of whole grains, paired with time and skilled fermentation, gives sourdough its signature structure and complex flavour. These blends also support gut health thanks to their rich content of prebiotics and polyphenols.
We explore these techniques in our 3-day Introduction to Sourdough workshops, where students work hands-on with freshly milled, additive-free flour.
Choosing Safe, Traditional Alternatives
For anyone wanting to avoid unnecessary food additives, the Provena Bread Subscription offers a reliable alternative. Every loaf is made using flour that meets EU safety standards and is free from bromate and other chemical improvers. These loaves reflect our ethos: nourishing bread rooted in tradition, health, and science.
We also offer starter kits and equipment to support home bakers who want to work with unprocessed ingredients and improve their skills through natural fermentation.
