Abstract
Orange juice is popular with consumers because of its unique taste, flavor as well as nutritional value which accounts for a large proportion of the global juice market. Concentrated orange juice (COJ), undergoes browning during storage seriously affecting its quality and commercial. This study was the first to evaluate the effects of epigallocatechin gallate (EGCG) and l-cysteine (L-cys) on Maillard browning of COJ during storage. The results show that EGCG and L-cys reduce significantly the production of 5-hydroxymethylfurfural (5-HMF), the characteristic product of Maillard reaction (MR), and the combined use of EGCG and L-cys was even more effective. Furthermore, the color of the treated COJ displayed negligible change after storage, with higher L* and b* values and marginally lower a* values. The flavor, taste, main volatile substances as well as rheological properties of the treated COJ were also determined; none of these properties were affected adversely during storage. This treatment method ensures that the key sensory quality and material properties of COJ are preserved by the proposed treatment while inhibiting Maillard browning during storage.

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
