What Does "Enriched Flour" Mean?
Before diving into King Arthur's specific products, it is important to understand what "enriched" means in the context of flour. During the milling process that creates refined white flour, the wheat kernel's bran and germ are removed, leaving only the starchy endosperm. This process strips the flour of much of its natural fiber, iron, and B vitamins, such as thiamin, riboflavin, niacin, and folic acid. To replenish some of these lost nutrients and address historical public health concerns like pellagra and beriberi, regulations were established in the U.S. requiring most refined flours to have these vitamins and iron added back, thus making them "enriched".
The King Arthur Difference: Unenriched and Unbleached
King Arthur Baking Company takes a different approach to flour production. According to their official statements, their standard retail wheat flours, including their well-known bread flour, are not fortified or enriched with any added vitamins, including folic acid. Their bread flour is also consistently unbleached and unbromated. This decision stems from a shift in consumer eating habits and the wider availability of nutrients in modern diets, which made the historical need for mandatory enrichment less critical for their target market.
The Impact of Unenriched Flour on Baking
For many home bakers, the unenriched nature of King Arthur bread flour is a key selling point. The absence of added chemicals and synthetic vitamins means the flour is a more natural product. However, it's the protein content, rather than the enrichment status, that most significantly impacts baking performance. King Arthur's bread flour has a high protein content (12.7%), which helps develop strong gluten networks, resulting in lofty, well-structured yeast breads. Bakers who switch from enriched, lower-protein flours to King Arthur's may need to adjust their hydration levels, as the higher protein flour can absorb more liquid. The key characteristics for bakers are the high quality and consistency, not the nutritional additives.
An Exception: King Arthur Special Patent Flour
It is important to note that while the standard blue-bag King Arthur bread flour is unenriched, some specialized varieties are. For example, King Arthur Special Patent Flour, often used in bread machines or for specific artisan applications, is enriched with niacin, reduced iron, thiamin mononitrate, riboflavin, and folic acid. Always read the ingredient list on the package carefully to confirm whether a specific King Arthur product is enriched or not.

| Bleaching/Bromation | Never bleached or bromated. | May be bleached and/or bromated, depending on brand. |
| Baking Performance | High protein (12.7%) for strong gluten development and lofty rise. | Protein content varies by brand; typically provides a reliable, consistent crumb. |
| Crumb Texture | Produces excellent texture in bread, known for its consistency. | Creates a dependable, classic texture, often softer depending on protein level. |
| Target Audience | Bakers prioritizing a high-quality, non-enriched, and non-bromated product. | General consumers seeking standard, government-regulated enriched flour. |
The Choice for Your Baking
The decision to use an enriched or unenriched flour ultimately comes down to your personal baking philosophy and nutritional preferences. If you are seeking a product with no added enrichments and prioritize consistency and high protein for your yeast-leavened baking, King Arthur's standard bread flour is an excellent choice. The company's long-standing commitment to quality and transparency in its ingredients is a significant factor for many loyal customers. It's a testament to the idea that a premium, unadulterated product can be more desirable than one that is simply enhanced with supplements.

Conclusion
In summary, King Arthur's flagship retail bread flour is not enriched with added nutrients, setting it apart from many national brands. This is a deliberate choice by the company, focusing on the quality of the base ingredient rather than on supplementation. While most refined flours are enriched to restore vitamins and minerals lost during milling, King Arthur provides a premium, unbleached, and unbromated alternative for bakers. For recipes where strong gluten and a consistent bake are paramount, King Arthur's high-protein, unenriched bread flour is a trusted ingredient, but bakers should always check labels for specific product variations.
