Dehydrated Devitalized Wheat Sourdough

Dehydrated devitalized wheat sourdough is produced by fermenting wheat flour with a starter culture of wild yeasts and lactic acid bacteria, then drying and processing the resulting dough. This process develops a characteristic sour flavour and improves the keeping qualities of the bread. The 'devitalized' aspect means the yeast has been deactivated, so it primarily acts as a flavouring and texture enhancer rather than a leavening agent.

Manufacturers add dehydrated devitalized wheat sourdough to impart a distinct tangy flavour and improve the texture and crust of baked goods. It is commonly used in a variety of bread products, including baguettes, bloomer loaves, and other speciality breads, to give them a 'sourdough' character without the longer fermentation times of traditional methods.

Dehydrated devitalized wheat sourdough is not considered a food additive and does not have an E-number. Its primary role is as a flavouring and processing aid. The Food Standards Agency (FSA) and Food Standards Scotland (FSS) do not set specific limits for its use, as it is a food ingredient. Evidence does not suggest adverse health effects from its consumption at typical levels found in bread products.
