Abstract
The fortification of salt with iron may greatly reduce the prevalence of iron deficiency globally, but fortification is complicated by iron-iodine interactions. To minimize this interaction, a spray dry microencapsulation system was developed. This study evaluates the creation and use of this system, producing engineered iron premixes for integration into coarse iodized salt. Bioavailable ferrous fumarate powders were encapsulated via spray-drying to produce particles which are too small to be detected visually (<20?m). Feed systems containing both suspended and dissolved ferrous fumarate were compared to find optimal feed conditions. The premixes were blended into iodized salt at 1000ppm-iron and stored at 40°C, ~60 percent RH. The salt was sampled periodically for 6 months to evaluate the effect on iodine stability. All encapsulated samples were more stable than the unencapsulated samples. The capsules ability to adhere to the salt as well as its colour and apparent bioavailability were evaluated. Stable double-fortified salt based on inexpensive, coarse, unrefined salt may be obtained economically by this approach.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
