Comparative analysis of lipid profiles and antioxidant potential of <i>Coriandrum sativum</i> fruit oils from Tunisia and Canada: influence of extraction methods
Bibliographic record
Abstract
This study investigated the lipid profiles and free radical scavenging potential of Coriandrum sativum fruit oils from Tunisia and Canada, utilizing three extraction methods: single screw, twin screw, and solvent extraction. Significant differences (p < 0.05) were found in the concentrations of essential fatty acids, including petroselinic, linoleic, oleic, and palmitic acids, between oils from the two regions. Notably, the twin screw extraction method applied to Tunisian coriander oils resulted in higher phytochemical content and superior free radical scavenging activity. The twin screw method demonstrated the highest efficacy, achieving an IC50 value of 1.4 mg/ml for the stable DPPH radical, while the solvent extraction method yielded an IC50 of 4 mg/ml for the same oil. These findings highlight the influence of geographic origin and extraction techniques on the nutritional and antioxidant properties of coriander oils.

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.
