Identification and Quantification of Fructoborate Ester Complex Using Liquid Chromatography Coupled with Q Exactive Orbitrap Mass Spectrometry
Bibliographic record
Abstract
The identification of fructoborate complex in food matrices using liquid chromatography coupled with quadrupole Orbitrap mass spectrometry was investigated in this study. The LC/MS method was established by optimization of mobile phases and direct infusion of FruiteX-B® brand calcium fructoborate (CaFB) solution to Q Exactive Orbitrap mass spectrometer to obtain MS operation parameters. The precursor ion m/z 367.10522 was dissociated further for conformation analysis of fructoborate complex. The method was applied to identify and quantify fructoborate in freeze dried apricot fruit and raisins. It was found that fructose-11B-fructose di-ester complex was present in these fruits. The results were further verified by multinuclear solid and liquid states NMR spectroscopy analysis.

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.
