The Effect of Caramel Coloring on the Multiple Degradation Pathways of Aspartame
Bibliographic record
Abstract
ABSTRACT: Multiple degradation pathways accounting for the breakdown of the dipeptide sweetener a‐L‐aspartyl‐L‐phenylalanine methyl ester (a‐APM) in 4 mM phosphate, pH 3.1 and a simulated cola beverage are described. At 20‐, 35‐, 45‐ and 55 °C caramel coloring concentrations greater than 700 ppm increased the rate of hydrolysis of the methyl ester forming a‐L‐aspartyl‐L‐phenylalanine. At 55 °C and pH 3.1 caramel coloring also enhanced the breakdown of a‐APM degradation products. The influence of caramel coloring on the rates of degradation varied considerably for a‐APM and each degradation product. A model is proposed based on the expected solution properties of caramel coloring which accounts for the enhanced degradation.

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.
