Flour bleaching agent
Flour bleaching agent is the agent added to fresh milled grains to whiten the flour by removing the yellow colour pigment called xanthophyll. It whitens the flour, which is used in the baking industry.
Overview
Usual flour bleaching agents are:
- Organic peroxides (benzoyl peroxide)
- Calcium peroxide
- Chlorine
- Chlorine dioxide
- Azodicarbonamide
- Nitrogen dioxide
- Atmospheric oxygen, used during natural aging of flour
Use of chlorine, bromates, and peroxides is not allowed in the European Union.[1]

In countries where bleached flour is prohibited, microwaving plain flour produces similar chemical changes to the bleaching process. This improves the final texture of baked goods made to recipes intended for bleached flours.[2]
