Microencapsulation of L-5-Methyltetrahydrofolic Acid with Ascorbate Improves Stability in Baked Bread Products
Bibliographic record
Abstract
Fortification of foods with L-5-methyltetrahydrofolic acid (L-5-MTHF) is challenging due to low stability to environmental conditions that include exposure to pH, moisture, and temperature. The objective of the present study was to stabilize L-5-MTHF using microencapsulation technology. L-5-MTHF microcapsules constructed with different core-to-wall ratios of L-5-MTHF, both alone or in combination with sodium ascorbate, yielded high (>89%) recovery of L-5-MTHF. Time-of-flight secondary ion mass spectrometry (ToF-SIMS) analysis confirmed successful encapsulation of L-5-MTHF with high core-to-wall ratios. Microencapsulation of L-5-MTHF alone with a high core-to-wall ratio significantly (p < 0.05) improved the stability of L-5-MTHF over the course of bread baking, performed both in pilot plant and in commercial baking conditions. Breads made with fortified flour containing sodium ascorbate coencapsulated with L-5-MTHF had recoveries of L-5-MTHF that were 97% and 77%, respectively, for pilot plant and bakery breads. Co-encapsulating L-5-MTHF with ascorbate also significantly (p < 0.05) improved stability during storage, as compared to breads that contained free L-5-MTHF.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
