Antioxidants: Science, Technology, and Applications
Bibliographic record
Abstract
Abstract Antioxidants are compounds that are employed to enhance shelf life and preserve the quality of fats and oils and lipid‐containing foods by suppressing oxidation reactions of their unsaturated components. These compounds could be naturally present, deliberately added, or generated during processing. Antioxidants are needed in small quantities to participate or interfere in the lipid autoxidation reaction cascade via various mechanisms. They should not impart any undesirable characters to the food, they should be stable, and they should be nontoxic. Application of these antioxidation differs depending on the nature of the food, conditions of intended processing, and storage. However, antioxidants that are deliberately added to foods are thoroughly scrutinized for their safety and toxicology aspects. Their usage in food is regulated under different legislatures in various countries. This chapter examines the purpose of antioxidant use, chemistry of antioxidant activity, and natural synthetic compounds that exert antioxidative activity in foods, as well as the relevant technological, toxicological, and regulatory considerations.

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.
