Antioxidant Activity of the Aqueous Extracts of Spicy Food Additives—Evaluation and Comparison with Ascorbic Acid in<i>In Vitro</i>Systems
Bibliographic record
Abstract
AbstractThe antioxidant activity of the aqueous extracts of five umbelliferous fruits-caraway (Carum carvi), coriander (Coriandrum sativum), cumin (Cuminum cyminum), dill (Anethum graveolens) and fennel (Foeniculum vulgare)-were investigated in comparison with the known antioxidant ascorbic acid in in vitro studies. The amount of aqueous extract of these five umbelliferous fruits and ascorbic acid needed for 50% scavenging of superoxide radicals was found to be 105 μg (cara way), 370 μg (coriander), 220 μg (cumin), 190 μg (dill), 205 μg (fennel) and 260 μg (ascorbic acid). The amount needed for 50% inhibition of lipid peroxide was 2100 μg (caraway), 4500 μg (coriander), 4300 μg (cumin), 3100 μg (dill), 4600 μg (fennel) and 5000 μg (ascorbic acid). The quantity needed for 50% inhibition of hydroxyl radicals was 1150 μg (caraway), 1250 μg (coriander), 470 μg (cumin), 575 μg (dill), 700 μg (fennel) and 4500 μg (ascorbic acid). The daily use of the above fruits in various forms is very common in India and the present study revealed strong antioxidant activity of their extracts that was superior to known antioxidant ascorbic acid and indicate their intake may be beneficial as food additives.Key Words: Spicesumbelliferous fruit extractantioxidantfood additivesascorbic acidfree radicals Additional informationNotes on contributorsS.

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.
