Regulatory Landscape

In the European Union, traditional sourdough is generally treated as a non-novel food based on documented consumption prior to 15 May 1997, which supports broad commercialization of classic sourdough breads and starter-derived ingredients. At the same time, there is no harmonized legal definition of "sourdough" across the EU or the United Kingdom, so product naming and claims typically need to align with general food information rules, including Regulation (EU) No 1169/2011 for ingredient disclosure, and with industry codes of practice, such as guidance from FEDIMA and UK industry initiatives. This keeps the need for substantiated on-pack communication around fermentation, starter use, and ingredient composition in focus.

Controls around additives and cross-border movement of preparations also affect formulation and trade. In January 2026, the EU published Commission Regulation (EU) 2026/196, updating purity specifications and related criteria for several commonly used additives, including hydrocolloids used for texture and stability, with applicability from February 2026 and transition periods extending to 2028. That change is expected to prompt audits of sourdough mixes and ready-to-use liquid products that include stabilizers. In the United Kingdom, HM Revenue and Customs guidance classifies liquid sourdough starter as a complex food preparation (CN 2106 90 98) rather than flour or a pure culture, so correct customs classification remains relevant for importers of liquid formats, alongside the 2024 updates to additives and novel foods rules that tightened limits such as ethylene oxide residues in authorized additives.
