Abstract
Objective To investigate antioxidantive action mode of egg white-derived peptides in vitro.Methods The egg white-derived peptides were separated by ultrafiltration from egg white protein hydrolysates(EWPHs) produced by papain into three fractions. The hydroxyl radical, superoxide anion scavenging activities and lipid peroxidation inhibition of three fractions were detected by the methods related to Fenton system, pyrogallol autoxidation, and linoleic acid emulsion system. The reducing power, DPPH radical scavenging activities and alleviation of H2O2-induced oxidative stress on porcine embryonic fibroblast(PEF) cell were also determined. Results EWPH-Ⅲ(MW3 kDa) accounted for 50.06% of the total amount of EWPHs. The values of hydroxyl radical, superoxide anion and DPPH radical scavenging activities were 52.86%, 35.05% and78.74% at the concentration of 5mg/mL, respectively. The percentage of inhibition of lipid peroxidation was74.57% at the same concentration. The cell survival rate reached 70.06% at the concentration of 2.5mg/mL.EWPH exhibited significant increase(P0.05) in antioxidant activity with a decrease in molecular weight of fraction values. Conclusion EWPH could act as a metal ion chelator, a hydrogen donor, as well as a radical stabilizer to inhibit lipid oxidation because of its antioxidant activity.

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.
