Antioxidant profile of Canada lettuce (Lactuca canadensis) and madeira vine (Anredera cordifolia) minimally processed
Bibliographic record
Abstract
This study aimed to evaluate the stability of natural antioxidants in minimally processed Anredera cordifoliaand Lactuca canadensisand their physical-chemical and antioxidant characteristics at time zero of storage (T0) and after 3, 6, 9 and 12 days, at a temperature of 7 °C. For the attribute color, L. canadensisdid not show significant differences between the parameters, whereas A. cordifoliashowed variation in its lightness from the third day of storage. Both vegetables had significant increments of pH, which ranged from 5.77 to 6.16 in A. cordifoliaand from 6.23 to 6.43 in L. canadensis. The contents of soluble solids also increased significantly, from 2.28 to 4.17 °Brix and from 4.89 to 6.30 °Brix in A. cordifoliaand L. canadensis, respectively. No significant difference was observed in total titratable acidity at any of the times evaluated (p>0.05). Among the bioactive compounds of the minimally processed vegetables, the contents of carotenoids, tannins, and total phenolic compounds were affected by storage, demonstrating that this process has an influence on the concentrations of the natural antioxidants studied.

How this classification was reachedexpand
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.
