Abstract
To develop a quadruple fortified salt(QFS) formulation that provides100 + % of RDA for iodine and vitamin B12 and 30–50% of RDA for iron and folic acid in forms that are organoleptically stable, bioavailable and acceptable to consumers Iodine was sprayed onto salt as an aqueous solution of potassium iodate. Iron was admixed as a solid premix, which was colour masked with TiO2 and encapsulated in soy stearine to provide a water-impervious coating. The iron core was made of ferrous fumarate, which was agglomerated to an average size matching salt grain, i.e., 300–500 μm. Folic acid and vitamin B12 were added either in the iodate spray solution or in the solid iron premix. The premixes and salt were stored at 25, 35 and 45°C at 65% RH for up to a year. The loss of iodine, folic acid and vitamin B12 were monitored. An optimized formulation was tested on the pilot scale at JVS Foods Pvt, Jaipur, India. Folic acid can be stabilized in the iodine spray solution, and triple fortified salt containing iodine, folic acid and encapsulated ferrous fumarate retained >90% of both the added iodine and folic acid for 6 months. Stable QFS was made by incorporating vitamin B12 in the solid iron premix at a 1:200 ratio. The process was scaled up to produce some 25 kg of iron and B12premix, sufficient for 5 tons of salt, or 500,000 daily doses of salt. Organoleptic testing of Indian meals produced with quadruple fortified salt were found to be acceptable by a consumer panel at the University of Delhi. Stable quadruple fortified salt that can provide up to 50% of RDA of folic acid and iron and 100 + % of RDA of vitamin B12 and iodine has been developed. The product was pilot tested and had high consumer acceptability. The formulation could reduce the incidence of maternal and infant mortality at a cost of less than 20¢/annum.

Full frame distilled prediction
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
