“Cold caramelization” of glucosamine under UV-C radiation
Bibliographic record
Abstract
The non-enzymatic browning of glucosamine (GlcN) under UV-C radiation at 25°C, referred to as “cold caramelization”, was examined. Several UV-C exposure times of 0, 20, 60, 120 min at two GlcN concentrations of 15% and 30% were chosen. The physicochemical properties, quantitation of α-dicarbonyl compounds and polyhydroxyalkyl pyrazines, alkylimidazoles and 5-hydroxymethylfurfural were determined in UV-C exposed GlcN caramels. The results revealed the possibility of generating GlcN caramel containing desirable compounds by applying UV-C. Longer UV-C exposure time produced caramel with higher content of glucosone and 3-deoxyglucosone, as well as the GlcN self-condensation products, fructosazine and deoxyfructosazine. Importantly, none of the tested neo-formed contaminants were detected in resulted caramels. Thus, UV-C treatment may be a newly advantageous method for producing GlcN caramel.

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.
