Antibacterial activity and improvement of the oxidative stability of soybean oil by 4-hydroxybenzyl isothiocyanate from white mustard seeds
Bibliographic record
Abstract
4-Hydroxybenzyl isothiocyanate (4-HBITC) is one of the most important secondary metabolite product in white mustard seeds. The antibacterial activity of 4-HBITC and the extent of lipid antioxidant activity were explored in this study. 4-HBITC was shown to have significant antibacterial effect on Escherichia coli, Staphylococcus aureus and Salmonella typhimurium, and its effect on gram-positive bacteria was superior to that on gram-negative bacteria. The addition of citric acid and ascorbic acid significantly enhanced the antibacterial effect of 4-HBITC. The antibacterial mechanism of 4-HBITC was identified for the first time to affect the integrity of the biological oxidation system rather than the permeability of cell membranes. In addition, 4-HBITC was found for the first time to maintain the stability of soybean oil, and this effect was also enhanced by the addition of citric acid. These results indicated the potential of 4-HBITC as a natural preservative and antioxidant in the food industry.

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.
