Unbleached Unbromated Enriched White Flour

Unbleached unbromated enriched white flour is made by milling wheat grains, removing the bran and germ, and then grinding the remaining endosperm into a fine powder. "Unbleached" means it has not been treated with chemical bleaching agents to whiten it, while "unbromated" indicates that potassium bromate was not used as a flour improver. "Enriched" means that certain nutrients, specifically iron and B vitamins (folic acid, riboflavin, niacin, and thiamine), are added back after milling.

This type of flour is a primary ingredient in many baked goods, providing structure and bulk. Manufacturers use it to create a wide range of products, including breads, buns, croissants, sweet rolls, muffins, and other pastries. It is valued for its consistent baking performance and neutral flavor.

Flour itself is a food, not a food additive. The enrichment of flour with iron and B vitamins is mandated by the FDA for certain flours to prevent nutrient deficiencies. Potassium bromate, which this flour is free from, is permitted by the FDA as a food additive, though JECFA has stated it is not appropriate as a flour treatment agent and did not set an acceptable daily intake. California has banned potassium bromate in food products starting in 2027. There is ongoing discussion regarding the safety of potassium bromate, with some studies suggesting potential health concerns, though the FDA maintains its permitted status at low levels.
