ANTIOXIDANT ACTIVITY OF COMMON BEANS (<i>PHASEOLUS VULGARIS</i> L.)
Bibliographic record
Abstract
ABSTRACT Four bean varieties with different hull colors (white, red, brown and black) were extracted with 80% acetone and evaluated for their total, hydrophobic and hydrophilic phenolics as well as tannin contents. The tannin content was measured using three different methods. Antioxidant capacity of the extracts was assessed using β‐carotene/linoleate and bulk corn oil model systems. The content of hydrophobic antioxidants was higher compared with the hydrophilic fraction in all tested bean types. Evaluation of antioxidant activity in a β‐carotene model system revealed that red, brown and black whole bean extracts were capable of inhibiting oxidation (33–52%) of β‐carotene as compared with the control when used at 100 p.p.m. level as catechin equivalents. In the corn oil model system, red, brown and black bean extracts inhibited the formation of conjugated dienes (CD; 20–28%), thiobarbituric acid reactive substances (TBARS; 44–52%) and hexanal (68–84%) when used at 100 p.p.m. level as catechin equivalents. The results of this study demonstrated that colored beans possess superior antioxidative activity compared with white beans.

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.
