Antioxidant activity of wheat extracts as affected by <i>in vitro</i> digestion
Bibliographic record
Abstract
Phenolic compounds from soft wheat and its milling fractions were extracted and their in vitro antioxidant activity evaluated. Non-hydrolyzed extracts were prepared by extracting phenolics into distilled deionized water. To make hydrolyzed extracts samples were first subjected to pH adjustments in order to simulate gastrointestinal pH conditions. Total phenolic content (TPC) was determined using Folin-Ciocalteu's procedure. Total antioxidant activity (TAA) was determined using Trolox equivalents antioxidant capacity (TEAC) assay and expressed as Trolox equivalents (TE). Antioxidant activity of wheat extracts was determined using the procedures of inhibition of beta-carotene bleaching, scavenging of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and inhibition of oxidation of human low density lipoprotein (LDL) cholesterol. The TPC and TAA of wheat extracts tested were significantly increased following hydrolysis. Similarly, the antioxidant activity, as determined by different procedures, was considerably increased when the samples were subjected to simulated digestion conditions.

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.
