Folic acid stability in the presence of various formulation components including iron compounds in fortified extruded Ultra Rice<sup>®</sup> over prolonged storage at 40 °C and 60% relative humidity (RH)
Bibliographic record
Abstract
Summary Ultra Rice®, a reconstituted rice product made by extrusion, has been successfully formulated for the fortification of market rice with vitamin A, iron and vitamin B1. As folic acid deficiency is a major health problem in areas targeted by Ultra Rice® technology, including India, Colombia and Brazil, it seems logical to incorporate folic acid into the existing formulation. The effects of various iron compounds on the storage stability of folic acid were studied. Four commercial ferric pyrophosphate compounds were chosen as iron sources and were added at different concentrations. A food‐grade whitener (TiO2) was also tested for its effects on folic acid stability and product colour. Folic acid was generally stable in the prepared rice formulations under high temperature and humidity (40 °C, 60%RH) – with the best sample retaining 95% and >75% of folic acid after 3 and 9 months of storage, respectively. The work demonstrated that folic acid fortification of rice through Ultra Rice® technology is technically feasible.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
