Dear Laura, The nitrate content in flours is very variable and dependent on the soil and fertilization conditions. You may get some initial ideas about the variability in a (very old) Danish report from the laboratories of the National Food Agency of Denmark: Allan Andersen: Kornprodukter - Sporelementer, pesticider, næringsstoffer, tilsætningsstoffer, nitrat og nitrit, ochratoxin-A og meldrøjer [Cereals and Cereal-Products Trace Elements, Pesticides, Nutrients, Food Additives, Nitrate and Nitrite, Ochratoxin-A and Ergots] Publikation nr. 93. Statens Levnedsmiddelinstitut, Centrallaboratoriet, Mørkhøj; Denmark, August 1984.
