First identification of 1-hydroxyoctan-3-one in apple purees: Use as a fruit quality segmentation marker and correlation with octane-1,3-diol concentration
Bibliographic record
Abstract
An organoleptic defect described as musty and/or fresh mushroom can occur in cooked apple products. GC-Olfactometry was used to characterize puree spoilage associated with sensory descriptors mushroom, cellar-like, musty, dusty or metallic. This approach, coupled with pure standards analysis allowed us to identify for the first time 1-hydroxyoctan-3-one in spoiled matrices. Using a targeted approach, 1-hydroxyoctan-3-one and octane-1,3-diol, were quantified by Stable Isotope Dilution Assay LC-MS/MS. Quantification results attested that these compounds exhibited a higher concentration in spoiled purees than in control ones and could thus be relevant markers of fruit spoilage. In a second time, the origin of 1-hydroxyoctan-3-one and octane-1,3-diol was investigated by contaminating several apple purees with specific fungal species. A Penicillium digitatum strain appeared to be the highest 1-hydroxyoctan-3-one producer, while a Botrytis cinerea strain led to a decrease of octane-1,3-diol concentration in spoiled products. It opens up avenues for the quality segmentation of fruits.

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.
